AMSOIL 5W-30 Outperforms Mobil 1

"I just put AMSOIL in my new Toyota at 6,000 miles and the mileage jumped three miles per gallon - a 10 percent increase. I can't understand why everyone doesn't use this fantastic product."

Product Description
AMSOIL 100% Synthetic 5W-30 Motor Oil exceeds the lubrication requirements of all modern automobile engines, providing tough lubricating protection in the most demanding operating conditions. It resists high temperature degradation and flows freely in cold conditions for substantial reduction in engine wear. AMSOIL 5W-30 provides excellent engine protection, maximum power, improved fuel efficiency and extended oil drain intervals.

Resists High Temperature Vaporization
AMSOIL Synthetic 5W-30 Motor Oil resists vaporizing in the high temperatures that vaporize petroleum motor oils. High vaporization loss leaves a thicker, higher viscosity oil than is recommended. The NOACK Volatility Test, which measures the weight loss of an oil due to evaporation, shows that most 5W-30 petroleum motor oils fail to pass the 13 percent ACEA pass/fail limit. In fact some oils lose as much as 25 percent of their weight to volatility. AMSOIL 5W-30 Motor Oil loses only 6.9 percent of its weight. AMSOIL 5W-30 remains a 5W-30. It provides consistent high temperature protection and reduces oil consumption and harmful emissions.

Resists Oxidation and Thermal Breakdown
AMSOIL Synthetic 5W-30 Motor Oil resists the damaging effects of heat, blowby chemicals and oxidation up to 10 times longer than petroleum motor oils. AMSOIL 5W-30 resists forming varnish deposits and sludge. It doesn't thicken like petroleum oils, but continues to cool and lubricate, providing peak engine performance and extended drain intervals. In addition, the advanced heat transfer capabilities and high lubricity of AMSOIL 5W-30 reduce excessive operating temperatures of engines, transmissions and gear boxes, so they run cooler, cleaner and longer.

Provides High Shear Stability
AMSOIL 5W-30 surpasses the North American SAE and European ACEA oil specifications for high temperature/high shear (HTHS) viscosity. It doesn't shear back to a lower viscosity oil in the high temperature/high shear conditions of today's smaller, high RPM automobile engines. AMSOIL 5W-30 maintains an extremely protective viscosity of 3.5 cP at 302°F (150°C) in the ASTM D-4683 High Temperature/High Shear Test, far exceeding test limits of 2.9 cP.

Provides Low Temperature Protection
AMSOIL 5W-30 remains fluid at temperatures as frigid as -60°F (-51°C). It permits easy engine cranking for fast starts and in sub-zero temperatures flows to all engine parts much faster than petroleum motor oils. The exceptional cold temperature properties of AMSOIL 5W-30 provide immediate cold start lubrication, greatly reducing engine wear and prolonging engine life.

Resists Deposit Formation
Because AMSOIL 5W-30's synthetic formulation resists oxidation so well, it runs naturally cleaner than petroleum motor oils. AMSOIL 5W-30 also contains special detergent/dispersant additives that, when tested after tens of thousands of miles of use in the crankcase, still exhibit outstanding deposit control. This combination of natural detergency and advanced additive package keeps AMSOIL 5W-30 effective for up to 25,000 miles or one year in non-turbocharged gasoline-fueled cars.

Prevents Rust and Corrosion
AMSOIL Synthetic 5W-30 contains special rust and corrosion inhibitors to protect iron parts, as well as copper, lead and aluminum bearing materials.

Mixing AMSOIL
AMSOIL 100% Synthetic 5W-30 Motor Oil is compatible with conventional petroleum oils; however, mixing AMSOIL 5W-30 with a conventional oil will shorten the drain period of AMSOIL 5W-30. Engine oil additives or after-market products are not recommended for use with AMSOIL 5W-30.

The 25,000 mile oil and filter was a life saver. We saved more time and effort not changing the oil every 3,000. We normally put 35,000 miles per year (3,000/month) on our transporter. We normally had to change the oil once a month, which to a do-it-yourselfer can be a Saturday morning every month spent crawling under the transporter getting greasy. With the 25,000 mile oil and filter combination we only have to spend two Saturday mornings per year slaving away under the transporter. How's that for saving time and money? Ten Saturday mornings I can find something better to do.
