AMSOIL 5W-40 Synthetic Premium Diesel Oil Provides Valuable Cost Savings

Although lubricants are often overlooked as a way to improve efficiency and minimize costs, use of AMSOIL 5W-40 Synthetic Premium Diesel Oil (DEO) over conventional 15W-40 oils presents fleets with an effective way to reign in costs without sacrificing protection. In fact, industry tests demonstrate a 1 percent fuel economy improvement by switching to 5W-40 diesel oil, while the Environmental Protection Agency’s (EPA) Federal Test Procedure confirms that AMSOIL 5W-40 Synthetic Diesel Oil provides up to 3 percent better fuel economy than conventional 15W-40 diesel oils (1.6 percent improvement at a mix of 55/45 city/highway driving).

For example, a single truck traveling an average of 120,000 miles per year and receiving an average of six miles per gallon consumes 20,000 gallons of fuel a year. At a price of $3 a gallon, annual fuel costs for this single truck are $60,000. By switching from a conventional 15W-40 diesel oil to AMSOIL 5W-40 Synthetic Premium Diesel Oil and achieving a 1.6 percent fuel economy improvement, the truck reduces its annual fuel usage by 320 gallons, saving $960. The savings mount when extended to larger vehicle fleets. A 50-vehicle fleet saves $48,000 in fuel costs, while a 100-vehicle fleet saves $96,000. (read more)


AMSOIL 5W-40 Synthetic Diesel Oil Offers Maximum Viscosity Protection

Hard working diesel engines present a serious challenge to the lubricants that protect them. Tight clearances and intense pressures can generate enough force to tear apart the molecular structure of the oil, causing permanent viscosity loss. Permanent viscosity loss is termed “shear” and leads to accelerated equipment wear and oil consumption.

Shear stability measures a lubricant’s ability to withstand shear forces without degrading to a lower viscosity. To meet CJ-4 requirements for shear stability, the American Petroleum Institute (API) requires diesel oils to pass the Kurt Orbahn 90-Cycle Shear Stability Test.

Resisting shear and maintaining protective viscosity in the harsh operating conditions of diesel engines is challenge enough for many diesel oils, but maintaining viscosity in the face of fuel dilution is another challenge altogether. Factors such as frequent starts, excessive engine idling, short trips and cold weather have contributed to moderate levels of fuel dilution in diesel applications for years, while recent issues with emission systems have brought the fuel dilution problem to a whole new level.

AMSOIL Synthetic 15W-40 Diesel Oil Field Study - Nordic Waste Refuse Hauler

Fleet owner switches from Shell Rotella T 15W-40 Diesel Oil to AMSOIL Synthetic 15W-40 Diesel Oil after seeing increased performance, protection and cost savings

In order to test the performance capabilities of AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil (AME), AMSOIL sought a partner with a fleet that operated in truly severe conditions. The perfect match was found in Duluth, Minnesota based Nordic Waste. Nordic Waste operates a fleet of 10 International refuse haulers, providing trash and recycling pickup to residential and commercial customers in the greater Duluth/Superior, Wisconsin region. Nordic’s trucks operate in the bitter cold of sub-zero winters as well as on humid summer days that can top out at over 90 degrees F. In addition, Lake Superior’s influence on the areas weather patterns can create extreme temperature swings just miles from the lake, something Nordic’s trucks encounter regularly. The company’s fleet runs 12 hours a day with frequent stops and redlined starts, all while hauling up to 22,000 lbs. of refuse and navigating the seriously steep hills of Duluth. Nordic Waste was initially installing Shell Rotella T 15W-40 before switching to AMSOIL. (read more)


Dodge Dually Surpasses 633,000 Miles With AMSOIL Lubes

Brad Walthour of Sunbury, Ohio speaks from experience when he talks about the qualities and benefits of AMSOIL lubes and filters.

“I rely solely on AMSOIL products to protect my investment in a wide range of outside temperatures on various and challenging terrain,” Walthour said. He uses AMSOIL Cold Flow Improver during the cold months. “The fuel has never gelled,” he said. “The engine and transmission have never been dismantled, rebuilt or replaced.” He averages 26 mpg an 55 miles per hour when he’s not towing anything and 11.5 to 14 mpg when towing. He calculates his oil change savings with AMSOIL products to be $300 a year, which doesn’t include the added protection against wear and extreme temperatures. (read more)


Truck Driver Takes Big Savings to the Bank Using AMSOIL Products

Terry Anderson Jr. of Chesapeake, Virginia saves money, time and fuel using AMSOIL products.

In fact, he saved $5,679 the first year he switched to AMSOIL lubes, filters and additives.

TAKING SAVINGS TO THE BANK - Terry Anderson with his 2005 Peterbilt dump truck. Anderson reports savings of $5,679 in one year using AMSOIL lubes and filters.

Anderson, owner of Terry Anderson Jr. Hauling Inc., owns and operates a 2005 Peterbilt dump truck with a Cat C-7 engine. He first installed AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil and an AMSOIL Ea Oil Filter in the truck. About a month later, he installed an AMSOIL By-Pass Filtration System.

“initially, I was concerned about the upfront cost of about $400, but soon found out it was money well spent,” he said.

Used oil analysis at 10,000 and 25,000 miles deemed the oil suitable for continued use, and he continued to run on the same oil.

“I changed my full flow filter after the second sample was sent in,” Anderson said. “The money I saved on oil alone in the first 25,000 miles paid for the by-pass filter system.” At one year, and more than 50,000 miles on the same oil, a third oil analysis reported the oil good for continued use. “The savings in the oil changes alone is enough to justify using AMSOIL and the by-pass filter system,” Anderson said. “More surprising was the increased fuel efficiency I saw on a daily basis.”

He typically changes the oil in the Peterbilt four or five times a year at $159 each change. “That is $759 a year.” He said. “I didn’t have to get my hands dirty changing the oil at all for a year thanks to AMSOIL and the by-pass filter system.”

Anderson also realized increased fuel efficiency. “After changing my Peterbilt over to AMSOIL lubricants and filters, I saw an increase in my fuel efficiency of one mile per gallon,” he said. His fuel efficiency increased again when he used AMSOIL Diesel Concentrate and Cetane Boost. “MPG is huge in my world,” Anderson said. “The more miles I can go on one gallon, the more money I put in the bank.”

With diesel fuel prices being so high, AMSOIL lubricants, filters and additives have saves Anderson’s company about $30 a day in improved fuel efficiency.

Savings he realized in the first 15 days with AMSOIL products paid for his initial investment, Anderson said. “The remainder of the year that $30 a day went straight to the bank along with the savings from the extended drain intervals.” (see savings chart)


Trucker Saves Thousands with AMSOIL

Blake Thompson is one happy trucker - in front of his first tractor trailer that he switched over to AMSOIL products.

Blake Thompson is one happy trucker.

Using AMSOIL products in his diesel engines saved him $5,000 in fuel costs in one year.

In 2006, Thompson was a diesel mechanic in Fortville, Indiana when he fist became familiar with AMSOIL products. Thompson had a dream of owning his own trucking company.

In November 2007, Thompson bought his first diesel tractor – a 1999 International with an M11 Cummins engine, an Eaton 4-9 transmission, five low-range gears, four high-range gears and a twin screw (two differentials) rear-end. “It was in beautiful shape with 580,000 original miles,” Thompson said.

Thompson is now a local hauler with two trailers. He uses one for hauling wood products – sawdust and wood chips, and the other for agricultural products, including corn and soy beans. The truck and tractor have a maximum gross weight of 80,000 pounds.

Thompson had his truck for only a short time before he switched to AMSOIL. With 590,000 miles on his tractor, he signed on the dotted line to become a commercial account. He purchased AMSOIL Engine Flush (AEF) and twin packs of AMSOIL 15W-40 Heavy Duty Diesel and Marine Oil (AME).

Thompson said he is more than happy he switched to AMSOIL products. He reports that while towing his hopper trailer his fuel mileage increased from 5.5 to 6.0 miles per gallon. While towing his walking floor trailer the fuel mileage increased from 6.0 to 6.5 miles per gallon.

Oil analysis at 10,000 and 20,000 miles showed the oil was “good for continued use.” Typical oil drain intervals for the big diesel engine is 20,000 miles.

Thompson was spending $75,000 a year on fuel. After investing $500 in AMSOIL products, he is spending $69,500 a year on fuel. That’s a savings of $5,000 per year!

Thompson is considering using oil analysis to extend his oil drain intervals even further, but Thompson said he is so happy about the fuel savings that he is satisfied changing the oil at his current drain intervals.

Thompson also uses AMSOIL Synthetic 5th Wheel Grease (GFW) “because it goes on easy and stays where you put it.” He can also see the difference in the spring shackles and king pins with AMSOIL Synthetic Heavy Duty Grease (GHD). Thompson says he used to have to pump several pumps, with brand X grease, before the grease started squeezing out. Now when he starts to pump the grease gun, the grease immediately starts to squeeze out of the joints. “That shows that the AMSOIL Heavy Duty Grease stays where you put it.”

Thompson’s business is growing. He recently bought another used tractor that has more than 470,000 miles on the engine. He says he will use AMSOIL 15W-40 Heavy-Duty Diesel and Marine Motor Oil in that one too, and he is eager to try the gear lube in his bearings, transmission and differentials.

Thompson has continued to buy AMSOIL 15W-40 Heavy Duty Diesel and Marine Motor Oil, Oil Sample Kits, Heavy Duty Grease and 5th Wheel Grease.


AMSOIL 409,000-Mile Oil Drain Interval Mack Engine Teardown

Haywood Grey went 409,000-miles without an oil change in his Mack E7-400After 409,000 miles without an oil change, the AMSOIL-protected Mack E7-400 engine in this truck was as wear-free as an engine in comparable service treated to TWENTY TIMES the oil changes.

COLONIAL HEIGHTS, VIRGINIA – “I didn’t see any surprises in there at all. Based on my experience with AMSOIL Motor Oil, it came out the way we expected,” said owner/ operator Haywood Gray (left) of his 1990 Mack E7-400 engine. It came out in good shape, exactly what you’d expect for a well-maintained engine with 630,000 miles. Yet the engine’s oil had not been changed for 409,000 miles!

Gray began using AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil (AME) in the E9-400 V-8 engine of his first truck, a 1984 Mack, after the engine accumulated 45,000 miles. For 280,000 miles, Gray changed his oil at 40,000-to 60,000-mile intervals though his oil analysis reports showed, without exception, that the oil was good for continued use. At 325,000 miles, Gray increased his oil drain interval to 100,000 miles. The engine was torn down at 600,000 miles when Gray decided to sell the truck. (read more)

AMSOIL Products Improve Efficiency and Reduce Operating Costs for Gerlach Trucking

AMSOIL INC., in conjunction with Gerlach Trucking of Erskine, Minnesota, conducted a field demonstration of its Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, Super Duty Oil Filters and Dual-Gard filtration system equipped with BE-110 by-pass filtration elements.

The test vehicle was a 1995 Freightliner FLD-120 powered by a Detroit 60 Series diesel engine and utilized mainly in long-haul transports. The testing covered a two-year period and the vehicle accumulated 212,326 total miles.

The goals for this demonstration included showing that the use of AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil, in conjunction with the AMSOIL Dual-Gard filtration setup and SDF Oil Filters, would result in improved efficiency, reduced operating costs and environmental benefits when compared to conventional petroleum lubricants and filtration methods. As mentioned, the evaluation was conducted using a 1995 Freightliner FD-120 equipped with a Detroit 60 Series diesel engine. The AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil was sampled at the manufacturer’s suggested oil drain intervals and monitored through the use of oil analysis to ensure its continued serviceability. The full-flow filtration units were also monitored and replaced at 12,000- to 15,000-mile intervals, while the By-Pass units were monitored and replaced at 24,000- to 30,000-mile intervals.

AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil is Correct Choice For Jeff Foster Trucking

With the help of Jeff Foster Trucking Inc. of Superior, WI, AMSOIL put its Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD), as well as its Dual-Gard filtration system, to the test.

Ten 1996 Kenworth Class 8 tractors used as interstate freight hauling vehicles and equipped with Cummins N-14 ESP3 diesel engines participated in the demonstration. Five trucks equipped with AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, AMSOIL BMK-12 Filter mounts and BE-110 By-Pass filtration elements utilized 120,000-mile oil drain intervals,20,000-mile full- flow oil filter change intervals and 40,000-mile By-Pass filter change intervals, while the other five trucks continued using petroleum motor oil, utilizing 20,000-mile oil and filter drain intervals.

The objective of the field demonstration was to prove that using AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, together with the AMSOIL Dual-Gard filtration system, would result in a reduction in operating expenses when compared to the use of conventional petroleum lubricants and filtration methods. Verification will be demonstrated through increased fuel economy, extended drain intervals, reduced oil consumption and reduced maintenance. (read more)


AMSOIL Proves Superior in Clark County Field Test

School BusIn order to demonstrate the effectiveness of AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil and the AMSOIL Dual-Gard filtration system in reducing operating expenses, AMSOIL and Direct Dealer Bill Andes began an ongoing field test in October 1998 with the bus fleet of the Clark County Board of Mental Retardation & Developmental Disabilities (MR/DD) in Springfield, Ohio.

Participating in the field test are three 1997 International 3800 school buses, two equipped with International 466 diesel engines and one with an International 466E diesel engine. Each had previously been running a conventional petroleum-based oil.

Engine wear rates have decreased significantly since changing to AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil. High temperature operating conditions have also been reduced. This leads to enhanced engine protection, and ultimately, to longer engine life. Because the engines have been operating more efficiently, three to five percent gains in fuel economy have also been realized. The chart below compares the levels of wear particles present in the previous conventional oil with the levels present in the AMSOIL as of May 2001. The condition of the AMSOIL at various testing intervals is documented below. (read more)


AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil 8.2% More MPG with AMSOIL Synthetic Lubricants
Replacing popular conventional engine and driveline lubricants with AMSOIL synthetic lubricants in Class 8 diesel-fueled vehicles increases fuel mileage up to 8.2% according to the findings of an independent test facility.

Fuel accounts for roughly 37 percent of Class 8 truck operating expenses, and reducing fuel expenses is a top priority for truck operators.

AMSOIL is the leader in the race to develop fuel efficient low-viscosity lubricants for trucking and other heavy-duty diesel applications. Independent laboratory testing shows AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil in the engine and AMSOIL synthetics in the drivetrain provide up to 8.2 percent more miles-per-gallon than other popular lubricants provide.

Diesel Oils Evolve With Diesel Engine Designs

The latest round of emission standards went into effect in 2007, requiring even more stringent NOx and particulate emissions reductions. While low levels of EGR technology (10-15 percent) were successfully applied in diesel engines to meet 2002 NOx emissions standards, most manufacturers incorporated increased EGR rates of 25-35 percent in order to meet 2007 standards. Increased EGR rates mean 2007 and newer diesel engines run hotter than their predecessors, requiring diesel oils meeting the latest API CJ-4 specification to be formulated with improved oxidation resistance properties to prevent thermal runaway and maintain engine protection.

Decreasing the level of sulfur in diesel fuel has been determined to be the most cost effective way to decrease particulate emissions. The introduction of ultra low sulfur diesel (ULSD) fuel in June 2006 dropped diesel sulfur levels from 500 ppm to 15 ppm in order to meet 2007 particulate limits, provide compatibility with NOx after treatment systems and enable high EGR rates.

In addition, in order to further reduce particulate emissions, diesel particulate filters (DPF’s) were incorporated into all 2007 and newer American diesel engines, and CJ-4 diesel oils are faced with the challenge of balancing engine protection with DPF life. Increased EGR. although effectively decreasing NOx emissions, results in less efficient combustion and increased levels of soot, and some of it finds its way into the engine oil. (read more)


AMSOIL Boosts CJ-4 Diesel Oil Offering

Upgraded formulation, new viscosity and longer drain intervals provide excellent value

AMSOIL has reformulated its Premium API CJ-4 Synthetic 5W-40 Diesel Oil (DEO). In addition, AMSOIL now offers a new 15W-40 Premium API CJ-4 Synthetic Diesel Oil (DME). These exceptional diesel oils provide a level of protection afforded only by a truly high quality synthetic oil – and do so over drain intervals of 3X (3 times) OEM recommended drain intervals. They are the premium choice for API CJ-4 emission-compliant diesel oil required by model-year 2007 and newer diesel engines. Formulated for vehicles fitted with exhaust treatment devices, DEO and DME are also backwards compatible, offering maximum protection to all diesel applications. (read more)


Superior Filtration Plays Important Role in Engine Protection

A great deal of emphasis is placed on the importance of using the most advanced high-quality lubricants, but superior filtration is often taken for granted. The general attitude displayed by many consumers is to use whatever is cheapest, even when they've invested is superior lubrication. While AMSOIL synthetic motor oils provide unbeatable protection, performance and economy, they require the assistance of filtration. Without filtration, by-products from the combustion process and abrasive materials ingested from the air will ultimately destroy an engine. (read more)


AMSOIL Synthetic Gear Lube Outperforms Valvoline Gear Lube

AMSOIL 75W-90 Synthetic Gear LubeHigh quality gear oils must lubricate, cool and protect geared systems. They must also carry damaging wear debris away from contact zones and muffle the sound of gear operation. Commonly used in differential gears and standard transmission applications in commercial and passenger vehicles, as well as a variety of industrial machinery, gear oils must offer extreme temperature and pressure protection in order to prevent wear, pitting, spalling, scoring, scuffing and other types of damage that result in equipment failure and downtime. Protection against oxidation, thermal degradation, rust, copper corrosion and foaming is also important.

AMSOIL submitted its 75W-90 Synthetic Gear Lube (AGR) and Valvoline 75W-90 Gear Lube to an independent laboratory for quality comparison tests. The gear lubes were tested according to ASTM testing procedures in several critical performance areas, including oxidation resistance, viscosity retention and cold temperature fluidity. Oxidation resistance was measured using the L-60-1 Thermal Oxidation Stability Test, viscosity retention was measured using the KRL Shear Stability Test and cold temperature fluidity was measured using the Brookfield Viscosity Test. Additional load carrying, wear, extreme pressure and scoring protection tests were performed exclusively on AMSOIL 75W-90 Synthetic Gear Lube using the L-37 High Torque Axle Test and the L-42 High Speed Axle Test.

Why Motor Oil Deteriorates

It is common knowledge that, at some point, engine oil must be changed. It's something that is preached relentlessly to vehicle owners by vehicle manufacturers, quick lubes and oil companies. But consumers are widely unaware of what exactly makes oil changes necessary.

Many factors contribute to a motor oil's demise, but it is essentially the accumulation of contaminants in the oil and chemical changes in the oil itself that make a motor unfit for further service. With time, it is inevitable that the oil will be contaminated by dirt or sludge, or succumb to the extreme pressures or temperatures found inside an engine. AMSOIL Motor Oils are formulated with the industry's most advanced synthetic base stocks and additive packages to combat the forces that deteriorate conventional oils. (read more)


What is the NOACK Volatility Test?
Volatization is a term used to describe what happens to a fluid as it is heated to the point it begins to "boil off." Upon reaching a certain temperature, oil will begin to lose some of its lighter weight molecules as they "boil off" and leave heavier weight molecules behind. Not only does this cause higher oil consumption, this process can also cause increased viscosity making the oil more difficult to circulate through the lubrication system. (read more)

Fuel Dilution Surfaces as Issue in Some Modern Diesel Engines

AMSOIL has documented two separate fuel dilution issues in modern diesel applications, one of which has forced the company to reduce its drain interval recommendations in a few applications using AMSOIL Premium CJ-4 Synthetic Diesel Oils (DEO, DME). AMSOIL recently released a technical service bulletin detailing that fuel dilution issue and providing updated recommendations for AMSOIL Premium Diesel Oils. (read more)


Diesel Oil Drain Interval Recommendations Adjusted

AMSOIL has documented increasing levels of fuel contamination (fuel dilution) in the engine oil of 2007-2008 light-duty Ford, GM and Dodge diesel pickups, and indications are that 2009-2010 models are also affected. Research indicates fuel dilution is intensifying due to the use of in-cylinder post-fuel injection during the engine’s exhaust stroke to regenerate the diesel particulate filter (DPF). Fuel in the oil reduces the oil’s life expectancy and effectiveness. Because diesel fuel is a natural solvent, fuel dilution in motor oil causes a decrease in viscosity which may lead to an increase in engine wear rates.

Although AMSOIL Premium Diesel Oils have shown the ability to maintain integrity under fuel dilution conditions, the abnormally high rate and unknown long-term effects have forced AMSOIL to adjust its drain interval recommendations as a precautionary measure in 2007-2010 Dodge 6.7L, Ford 6.4L and GM 6.6L LMM light-duty turbo-diesel pickups. In these applications, AMSOIL recommends changing AMSOIL Premium API CJ-4 Synthetic Diesel Oils (DEO, DME) at the manufacturer-recommended drain interval. Drain intervals may be extended further with oil analysis.

AMSOIL previously announced a fuel dilution issue in 2007-2009 on-highway Caterpillar C13 and C15 engines that forced the company to adjust its drain interval recommendation in those applications to the manufacturer-recommended drain interval.

In all other applications, AMSOIL full synthetic diesel oils are recommended for three times (3X) the OEM recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first, while Synthetic Blend 15W-40 Heavy Duty Diesel and Gasoline Motor Oil (PCO) is recommended for the longest OEM recommended drain interval. Drain intervals may be extended further with oil analysis.

AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
