API SN, Meets and Exceeds Chrysler MS-12633.

Supreme 9000™ Full Synthetic 0W-40 engine oil provides extra protection during short haul driving conditions and is recommended for gasoline fueled automobile and light duty truck engines specifying Chrysler MS-12633.

Our fully synthetic 0W-40 is a multi-grade gasoline oil engineered with the finest quality of synthetic base oils, an advanced performance additive package and a viscosity index improver. This unique blend creates a premium, longer lasting oil that withstands a higher heat range than conventional oil. Using proprietary friction modifiers, Micron Moly® and Penetro®, Supreme 9000™ Full Synthetic 0W-40 quickly plates to metal surfaces, creating a slippery, tenacious shield that prevents metal-to-metal contact. By reducing friction and wear, Supreme 9000™ Full Synthetic 0W-40 protects critical engine parts and increases engine efficiency, engine life and fuel economy.

Supreme 9000™ Full Synthetic 0W-40 keeps engines exceptionally clean and free from oil residue and sludge, allowing the oil to flow freely and lubricate properly. For extra protection in cold weather, our 0W-40 full synthetic oil offers superior cold cranking and oil pumpability at low temperatures.

Supreme 9000™ Full Synthetic SAE 0W-40 meets the needs of Chrysler SRT engines, where Chrysler MS-12633 is specified. This specialty 0W-40 engine oil may be used in SRT engines originally recommending Chrysler MS-10725 and MS-10850.

    Schaeffer's 0w40

    Posted by Allen Walker on Jun 18th 2023

    Absolutely the best synthetic oil I've ever used. 2005 Infiniti FX45 with 4.5 liter V8; I started with Amsoil, went to Redline, then Royal Purple and now Schaeffers. For the last four years mpg has been 14.7 combined driving. Switched to Schaeffers 0W40 and now my mpg, after three weeks driving including two road trips, my mpg is steady at 18.3. I do not understand this, but I am very happy about it. I think I've found my brand and formula. Try it yourself. Pricey but amazing.

    So far I really like this oil in my 2005 Infiniti FX45. Redline 5W30 was good, Royal Purple 0W40 was better, but this Schaeffer's 0W40 formula blows them all away. My engine with 212k miles runs stronger, smoother and quieter than ever before. It's like a whole different vehicle now. Very happy.
