SECOND: Oil must act as a cooling fluid to assist in dissipating the intense heat generated by combustion which can quickly reduce an engine to scrap. THIRD: It must flush moving parts to clean them of abrasive particles which cause excessive wear and premature engine failure. FOURTH: It must seal the rings for increased power and lower combustion products contamination.The physical properties of AMSOIL operate over a wide range of temperature from -60?F to +600?F. Because of the thermal stability of AMSOIL it maintains its proper viscosity, does not break down chemically, and retains its effectiveness. AMSOIL contains an additive package which is specifically designed for synthetic oils and today's severe automotive conditions.Drain Intervals: Drain intervals may be extended, but oil should be changed once per year under normal driving conditions. Severe operations such as excessive idling, abnormally high temperatures, or dusty climates may dictate shorter drain periods.Most Asked ?sWhen Should You Put Amsoil Into New Automobile Engines? Most now say that it's OK from the first start; others say to use regular oil & ZDDP for several thousand miles.Summary of Benefits= Increases Gas Mileage= Reduces Oil Consumption= Superior Lubrication at All Temperatures= Faster Sub-Zero Starting= Longer Engine Life= Rating: SL, SJWILL IT WORK IN AIR-COOLED ENGINES? Yes, extremely well. Air-cooled engines normally run hot and AMSOIL reduces the engine tempera ture, therefore prolonging engine life.WILL AMSOIL QUIET NOISY LIF TERS? Yes, provided they are simply dirty and not damaged by wear.WILL AMSOIL DECREASE OIL CONSUMPTION?Yes, under normal conditions.WHAT ABOUT OXIDATION? Having a film strength of 8 to 10 times more than a petroleum being less susceptible to extreme temperatures than a petroleum and having been properly for mulated with the correct additives into a syn thetic base...AMSOIL therefore resists oxida tion.AMSOIL UPDATE - More Zinc!Amsoil now has an oil with more zinc. They now have enough so you do not need any additional zinc additives. This oil will give superior protection to all classic cars with flat tappets. It also gives extended protection against rust & corrosion during extended storage. These oils are compatible with the old Amsoil oils, so you can just switch right over. This new oil is called "Z-Rod." 10W30 Z-Rod oil C7961 2 lbs. 20W50 Z-Rod oil C12576 2 lbs.Important News About Oil !!!!! ZDDP !!!For 70 years, engine oils have used Zinc Dialkyldithiophosphate (ZnDDP) as the most common anti-wear component.In 2005, in an effort to guarantee longer catalytic converter life, the American Petroleum Institute had reduced the amount ofZnDPP to the point that it was of little use in engines with hydraulic lifters. The point between the lifter and the cam lobe has the highest stress/wearload in the Corvair engine. Sure the new oils are "better" for newer engines, but what can you do for your older engine? 1) Check your oils. There are still a few high performance & some synthetic oils with enough ZnDDP, but you must check carefully. Some "racing oils" do not have the necessary additives for street use. See above for NEW ZINC RICH oils from Amsoil. 2) ZnDDP Additive - ZDD Plus. 4 oz. bottle to treat 4-5 quarts of oil. Contains 2.2 oz. of ZnDDP & 1.8 oz. of regular oil as a transfer agent. This adds enough ZnDDP to the newer oils to protect the lifters & cam shaft for a normal oiI change period. Is it absolutely necessary? Most authorities say that it is; the cost is minimal for the protection it offers. 4 oz. Bottle of ZDD Plus C379X 6 oz. ea.
