NEW Long Life Synthetic Gear Lubes from AMSOIL

AMSOIL INC. of Superior, WI has two new gear lube formulations specifically for extended service life up to 500,000 miles in over-the-road trucks with large drive axle sumps. Available in 75W-90 and 80W-140 viscosities, AMSOIL Long Life Synthetic Gear Lubes are engineered to protect gears better than conventional gear oils, resisting acid, carbon and varnish formation and oxidative breakdown. Features and benefits of AMSOIL Long Life Synthetic Gear Lubes include: · Protects against wear for improved equipment life · Shear stability for consistent viscosity throughout its service life · Greater range in operating temps for excellent "All Season" performance Formulated specifically for Class 8 heavy-duty trucking, these oils meet Arvin/Meritor (O-76E, O-76N for 75W-90) and (O-76A, O-80 for 80W-140) for petroleum and synthetic oil viscosities, GO-J, GO-J+ specifications set by Mack, and Dana SHAES 256 for 500,000-mile oil drains. Both oils are still very good recommendations for the automotive market as well. AMSOIL Long Life Synthetic Gear Lubes also meets API GL-5 & MT-1, MIL-PRF-2105E, Navistar TMS 6816, plus hypoid gear oil specifications from all foreign and domestic manufactures such as GM, Ford and Daimler Chrysler.

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
