I can't understand why everyone doesn't use this fantastic product." G.D., Chicago, Illinois 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. SERVICE LIFE AMSOIL Synthetic 5W-30 Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline fueled vehicles as follows: • Normal Service(3) – Up to 25,000 miles or one year, whichever comes first. • Replace AMSOIL Ea oil filter at 25,000 miles or one year, whichever comes first (Change other brands at standard OEM* intervals). • Severe Service(4) – Up to 15,000 miles or one year, whichever comes first. • Replace AMSOIL oil filter at 15,000 miles or six months, whichever comes first (other brands at standard OEM* intervals). • In all other applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval. *OEM – Original Equipment Manufacturer (1) Where the engine or operating conditions have been modified from the original manufacturers’ design, drain oil at the owner’s discretion or extend based on oil analysis. Examples include the use of performance computer chips; modified exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturers. (2) Engines are in good working condition and within the factory design settings.

AMSOIL Synthetic 10W-30 Motor Oil is highly resistant to vaporization, losing only 6.6 percent of its weight in high temperature service. In fact, AMSOIL Synthetic 10W-30 Motor Oil resists vaporization so well, it surpasses rigorous European standards, set at 13 percent weight loss in high temperature testing. In the engine, AMSOIL Synthetic 10W-30 Motor Oil's superior vaporization resistance keeps fuel economy high; oil circulation efficient; and oil consumption, emissions, and most importantly, engine wear, to a minimum. Provides High Shear Stability The shearing forces generated inside today's smaller, high RPM automobile engines can literally tear apart the molecules of conventional oils. AMSOIL 10W-30, because of its unique synthetic construction, withstands shearing forces. AMSOIL 10W-30 doesn't thin out and lose viscosity like conventional oils do. AMSOIL Synthetic 10W-30 Motor Oil surpasses the North American AAMA, Japanese JASO and European ACEA oil specifications for high temperature/high shear viscosity. AMSOIL 10W-30 delivers long-lasting 10W-30 protection to prevent wear under the hottest and heaviest-loaded conditions. Resists Oxidation and Thermal Breakdown AMSOIL 10W-30 resists oil breakdown from heat, blowby chemicals and oxygen longer than do conventional oils. AMSOIL 10W-30 resists forming varnish deposits and sludge. It doesn't thicken like petroleum oils, but continues to cool and lubricate, providing peak engine performance, power and protection. In addition, the advanced heat transfer capabilities and high lubricity of AMSOIL 10W-30 keeps engines, transmissions and gear boxes running in their optimal temperature range, for top performance and long life. Provides Low Temperature Protection AMSOIL 10W-30 remains fluid at temperatures as low as -54°F (-48°C) so it permits easy engine cranking for fast starts. During sub-zero temperatures, it flows to all parts of the engine in much less time than conventional petroleum oils take, which greatly reduces the rate of wear and increases engine life. Resists Deposit Formation Because AMSOIL 10W-30's synthetic formulation resists oxidation so well, it runs naturally cleaner than conventional oils. AMSOIL 10W-30 has a superior detergent/dispersant additive package that, when tested after tens of thousands of miles of use in the crankcase, still exhibits outstanding deposit control. Inhibits Rust and Corrosion AMSOIL 10W-30 contains powerful rust and corrosion inhibitors to protect iron parts and bearing materials. Provides Extended Drain Intervals Due to its superior synthetic composition and advanced performance additives, AMSOIL 10W-30 performs much longer than do conventional petroleum and other synthetic motor oils. No other major oil manufacturer matches AMSOIL's 25,000-mile or one-year drain interval recommendations. MIXING AMSOIL AMSOIL 100% Synthetic 10W-30 Motor Oil is compatible with conventional petroleum oils; however, mixing AMSOIL 10W-30 with a conventional oil will shorten the drain period of AMSOIL 10W-30.
