Emissions Control Systems Place Unique Demands On Diesel Oils

AMSOIL diesel oils have adapted to overcome new challenges.

TECH TALK
Dan Peterson, Vice President, AMSOIL Technical Development

Mark Nyholm
Technical Product Manager,
Heavy Duty

I read an article on diesel engines and exhaust emissions in a recent issue of Diesel Power magazine that really hit home. Many diesel enthusiasts are on a quest for more horsepower and torque through a laundry list of modifications that takes the word "stock" and tosses it right out the window. These modifications involve removing many of the systems engine manufacturers have implemented to comply with Environmental Protection Agency (EPA) regulations governing exhaust emissions.

If you've ever read a diesel magazine or talked to anyone in the industry, 2007 was the year that light-duty turbo diesels took a turn for the worse in customers' eyes. It was the introduction of the diesel particulate filter (DPF), which is designed to manage the particulates and soot released by the vehicle's exhaust. David Kennedy from Diesel Power wrote in that article, "How many times have you gotten up in the morning, gone outside, taken a deep breath and said, ‘you know, the air here is just too clean'?" Although you may believe this DPF thing is the worst invention ever, it's in your exhaust system for a reason. So instead of despising it and being confused about what it does and how it does it, let's discuss this device to improve your understanding.

The diesel combustion process is imperfect. For example, diesel fuel does not burn completely, leaving soot as a byproduct. The DPF is a honeycomb-like filter positioned downstream from the exhaust manifold that catches soot. As soot accumulates over time through normal driving, the DPF begins to plug. A diesel engine requires huge amounts of air for combustion and needs to exhale that air through the exhaust very quickly. A DPF that can't pass enough air creates restriction, which leads to reduced power and fuel economy, and eventually could choke off the engine entirely. Original equipment manufacturers (OEMs) designed a process to clean the filter called regeneration. Your truck monitors DPF restriction and automatically begins a regeneration cycle when the pressure exceeds a specific limit. You'll notice when the system activates because a DPF regeneration light will illuminate on the instrument cluster.

So, what is the regeneration cycle? When the DPF is near capacity, soot trapped in the filter is burned, freeing the plugged media and enabling the filter to remain serviceable. Most emissions-compliant turbo-diesel pickups clear the DPF by spraying raw diesel fuel into the cylinder on the exhaust stroke after combustion occurs. Diesel fuel injected on the exhaust stroke does not combust; instead, it travels down the exhaust stream until it reaches the DPF, where it combines with soot and burns. This generates the high temperatures necessary to burn soot trapped in the DPF.

This process is designed to regenerate the DPF and works fairly well; however, since fuel injected on the exhaust stroke does not combust, it tends to wash directly past the piston rings and into the crankcase, diluting the engine oil. That's a pretty big issue considering diesel fuel and engine oil readily mix, resulting in reduced oil viscosity. I've seen oil analyses from trucks with fuel dilution of up to 10 percent. That might seem relatively low, but 10 percent fuel dilution can cause your 15W-40 engine oil to thin to the equivalent of an SAE 20. That's a big reduction in engine protection for engines designed to operate with a 15W-40.

Because this issue reduces the lubricant's ability to protect the engine and extend drain intervals in turbo-diesel pickups, AMSOIL formulated OE 15W-40 Synthetic Diesel Oil (OED) as a cost-effective alternative to more expensive long-drain-interval products. We cannot control the thinning effects the DPF regeneration system has on the oil, so we formulated an oil to accommodate these effects. OE Diesel Oil is highly shear-stable to provide maximum protection against shear-induced viscosity loss, helping to minimize the loss associated with fuel dilution. It provides security in protecting the engine at the OEM drain interval, especially in applications where fuel dilution is an issue. Published, AMSOIL Magazine 08/12.

AMSOIL Synthetic Diesel Oil Articles and Testimonials


"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


FULL WARRANTY


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.

AMSOIL Now An ISO Certified Manufacturer
AMSOIL recently received ISO 9001:2000 certification of our Quality Management System (QMS). NSF International Strategic Registrations is the registrar that has verified our QMS meets the requirements of the ISO 9001:2000 standard, the most widely utilized quality standard throughout the world for quality management systems.
