Innovation and Leadership Gear Lube

AMSOIL has a documented history of innovation and leadership in racing. In 1972, AMSOIL introduced the first American Petroleum Institute rated 100% synthetic motor oil for automotive applications. AMSOIL was the first to introduce a concept of extended drain intervals with a recommended 25,000-mile 12-month drain interval for normal driving conditions. AMSOIL lubricant technology has been field tested over the last 35 years in the most severe driving conditions. Including family fleets, over the road big rigs, towing, hauling and of course racing.

AMSOIL Lubricants ...
AMSOIL DOMINATOR - The Best Synthetic Racing Oil dramatically outperform conventional petroleum racing oils. Synthetic lubricants are engineered, synthesized lubricants consisting of 100% PAO Formulated Basestock Technology, and maybe made to fulfill virtually every lubricating need. The molecular uniformity of synthetic lubricants promote superior lubrication and friction reduction, which in turn promotes superior heat control, wear control and energy efficiency. Molecular uniformity also helps synthetics maintain their protective viscosity in high-temperature operations, which also promotes superior wear control. Because they are derived from pure chemicals, synthetic lubricants contain no contaminants or molecules that “don’t pull their own weight”. Synthetic racing Lubricants contain no paraffin or wax molecules like conventional lubricants.

They reduce friction, heat and wear for maximum power, performance and fuel efficiency. Resistant to high temperature burn off, chemical breakdown and "sludging" keeping engines cleaner. Provides low temperature fluidity for fast, dependable winter starts and cold start protection. Exceed the most demanding world-wide performance standards and meet warranty requirements for all domestic and imported passenger car engines, both turbo-charged and non-turbo-charged. AMSOIL Signature Series 0w-30 provide up to 35,000-mile or 1-year drain intervals. AMSOIL DOMINATOR The Best Synthetic Pro Racing Oil !

Q: Do i need high zinc in my oil ?

High zinc is only needed for flat tappet cams, engine break-in and High Horsepower racing applications. If your not in need of high zinc for those reasons, it doesn't matter which oil you use although Amsoil 10w40 and 20w50 and AHR 60 all have zinc added as well as Amsoils Dominator line of racing oils. I use Amsoil SSO, 0w30 in all my vehicles. This use to be the racing oil, but now is marketed for passenger and high horsepower street engines as well. It has a guarantee of 1 yr / 35k mile drain intervals, whichever comes first in passanger car applications. Amsoil stands behind their product 100 percent and uses only the finest quality additives and base stocks, not looking to make a more profit by cutting corners or by selling a product with less than perfect materials.

Q: Synthetic motor oil is not good with flat tappet cams!!!

This is by far one of the biggest myths out there.

Sulfur in motor oil actually acts as a contaminant that promotes the formation of sludge and other by-products of lubricant break-down. It is true that PAO based synthetics contain no sulfur because they are formulated from pure chemicals rather than refined from crude oil. Conventional motor oils do contain trace amounts of sulfur; the portions that cannot be refined out. I'm sure what you are referring to is Zinc and Phosphorous which is an important component when running flat tappet camshafts.

It could also depend on what type of synthetic oil you are referring to. If it is an API (SM) rated synthetic motor oil, then you would have reduced levels of Zinc and Phosphorous, and this would indeed be a bad choice with a flat tappet camshaft.

Below is a direct quote from an Amsoil Technical Service Bulletin.

FLAT TAPPET CAMSHAFTS

Issues:
Engine oils contain anti-wear additives and the most common anti-wear chemistry is zinc dialkyldithiophosphate (ZnDDP), which contains a combination of zinc and phosphorus. In 2005, in an effort to guarantee catalytic converter performance in new vehicles, the American Petroleum Institute (API) and International Lubricants Standards Approval Committee (ILSAC) instituted API SM and IL-SAC GF-4 quality standards which reduced the maximum limit for phosphorus to 0.085% and 0.080% respectively. Both API SM and ILSAC GF-4 specifications also contain a minimum phosphorus content of .065% and .060%.

Previously, API SL/ILSAC GF-3 oils were restricted to 0.10% phosphorus level, so a concern arose that oils containing lower levels of zinc/phosphorus could provide insufficient protection in high pressure areas of flat tappets and camshaft lobes found in many older cars and high-performance engines.

Technical Discussion
Proper assembly lubes and oil additives should be used during the break-in phase for all new or rebuilt engines with flat tappets. These additives provide the extra protection required at the point of contact during break-in to help the flat tappet face to properly mate with the cam lobe. Once the break-in phase is completed, these additives should not be used because of other engine life issues created by long term use of these materials. AMSOIL does not provide break-in assembly lubricants, but one of the common products is GM E.O.S., which is an assembly lubricant and is not, as stated by GM, an engine oil additive. AMSOIL does not recommend using any engine oil additives with AMSOIL engine lubricants.

High-performance modified engines benefit from oils with superior film strength and anti-wear properties. The flat tappet/camshaft lobe interface is the one area in an engine that has extreme contact load. This load increases significantly where non-stock, high-pressure valve springs are employed so the use of properly formulated engine lubricants is extremely important to reduce wear and extend flat tappet/camshaft life. In these applications,

AMSOIL recommends motor oils containing high levels of zinc/phosphorus for superior protection.
