Corporate Announcement
AMSOIL Signature Series 0W-30 Synthetic Motor Oil is the industry benchmark in lubrication technology. Engineered with the world’s finest synthetic base oils and high performance additives, AMSOIL Signature Series 0W-30 is designed for those who demand the absolute best in motor oil performance. The exclusive “extended drain” formulation delivers superior engine protection and maximum fuel economy. AMSOIL Signature Series 0W-30 is a premium grade synthetic motor oil that exceeds the requirements of modern, high-performance engines and older engines. It replaces other 0W-30, 5W-30 and 10W-30 motor oils and consistently outperforms competitive conventional and synthetic motor oils.

Do you run a flat tappet cam?

Protect your flat tappet camshaft lobes with products containing high levels of zinc/phosphorus (ZnDDP).
The below lubricants are recommended, they contain the proper level of zinc/phosphorus to protect against wear without the use of zinc additives.

Why should I protect my engine with AMSOIL?
Engine oils contain anti-wear additives and the most com-mon anti-wear chemistry is zinc dialkyldithiophosphate (ZnDDP), which contains a combination of zinc and phos-phorus. In 2005, in an effort to guarantee catalytic con-verter performance in new vehicles, the American Petro-leum 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 con-taining lower levels of zinc/phosphorus could provide insuf-ficient protection in high pressure areas of flat tappets and camshaft lobes found in many older cars and high-performance engines.

Proper assembly lubes and oil additives should be used dur-ing 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 prod-ucts 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 AM-SOIL 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 signifi-cantly where non-stock, high-pressure valve springs are em-ployed so the use of properly formulated engine lubricants is extremely important to reduce wear and extend flat tap-pet/camshaft life. In these applications, AMSOIL recom-mends motor oils containing high levels of zinc/phosphorus for superior protection.

AMSOIL AMO, ARO, HDD, TRO, and AHR all contain high levels of zinc/phosphorus maximizing flat tappet/camshaft life in stock and modified applications.

AMSOIL 10W-40 (AMO) and 20W-50 (ARO) are premium synthetic formulations which are recommended for API SL (gasoline)/CI-4 Plus (heavy-duty, on-road diesel) specified applications. They are an outstanding choice where high zinc containing protection is required in late model hot rods requiring extra camshaft protection.

AMSOIL (HDD) is a 5W-30 weight combination diesel/gasoline oil with a higher starting TBN to handle the signifi-cant stresses from high soot loading and acid generation in modern diesel engines. HDD contains the high phosphorus and zinc required for long life.

AMSOIL 20W-50 (TRO) is a premium synthetic racing oil with superior film strength and anti-wear protection for gasoline engines. It is an excellent choice for street or race cars, hot rods, trucks or boats. TRO is the preferred choice for highly modified, high horsepower engines requiring the extra protection required by flat tappet camshaft engines.

AMSOIL SAE 60 (AHR) is a super heavy weight racing oil de-signed for alcohol and nitro burning race engines where viscosity loss associated with fuel dilution is a concern. AHR includes a high dose of zinc containing anti-wear chemistry that race engines require.
AMSOIL with Championship Off Road Racing

AMSOIL INC, The First in Synthetics, will continue its rise in the off-road racing market after signing an exclusive, three-year marketing deal with Championship Off Road Racing. Starting in 2008, AMSOIL will become the Official Oil of CORR through 2010. CORR offers the top teams in short course off-road racing. The series will broadcast eight rounds of the Baldwin Cup on NBC Sports. Bill Weber and Wally Dallenback, both of NASCAR fame, will provide the play-by-play and analysis for the 13.5 hours of network coverage. CORR has also announced that both its NBC and SPEED coverage will include live, High-Definition broadcasts, and that the NBC coverage will increase from 60 minutes of airtime per race in 2007 to 90 minutes per race in 2008. “AMSOIL believes in the vision and ambition that CORR has demonstrated over the past few years,” says AMSOIL Race Program Manager Jeremy Meyer. “They have the top competition, the best television package and the resources to push off-road racing into an exceptional period of growth and excitement for years to come. Along with our off-road racers Scott Douglas and Mike Oberg, the addition of CORR is a major boost to an already successful racing program at AMSOIL.” The 2008 season begins April 26-27 at the Los Angeles County Fairlplex, just ten miles from downtown Los Angeles. The Pro 2 and Pro 4 points races from that event will air live on SPEED with the Cup races airing on NBC in May. CORR will also race in Chula Vista, Calif., and Primm, Nevada.
