HEAVY DUTY DIESEL ENGINE OIL

  • 5W-40 Green Diamond Fleet Oil is a 100% pure synthetic using only Group III base oils.
  • 15W-40 Green Diamond Fleet SEMI Synthetic Oil is a synthetic blend of Group II and Group III base oils.
  • 15W-40 Green Diamond Fleet FULL Synthetic Oil is a 100% pure synthetic using only Group III base oils.

Infused with FR3 Nano Lubricant Technology

The infusion of our patented FR3 Nano-Technology and CK-4 additive package provides unsurpassed levels of longevity and performance, all while keeping the oil cleaner longer and providing better mileage and horsepower. Green Diamond Fleet Oil was formulated to meet severe operating conditions such as hauling heavy loads, stop and go and operation in areas of high airborne particulates.

All Green Diamond Fleet Oil is fully formulated CK-4 motor oil with high detergency plus exceptional oxidation and thermal stability, preventing deposits and oil breakdown and making longer drain intervals possible. In addition to exceeding the API CK-4 specification, the HSS 5W-40 Green Diamond Fleet meets the requirements from Ford for added wear protection as stated in Ford Specification WSS-M2C171-F1 (Not all CK-4 specification oils meet both the CK-4 and the Ford specification).

Green Diamond Fleet Oil is recommended for most diesel engines. The CK-4 specification is backwards compatibles with the CJ-4 and the CI4 Plus.

    This is my second oil change with this oil. It makes my old 7.3 run smooth and quiet. It also has everything in it. No needed additives. Stiction eliminator and FR3 already in it!

    Switched from Shell Rotella T-6

    I am pleased with Green Diamond 5/40 W, increased power and fuel economy with my diesel. I like the fact that it meets Ford’s spec’s and that FR-3 is an additive. The oil appears to be holding up very well and I am beyond my normal oil change mileage. Do I still have to add HSS SE every 20K? I would switch my gas engine oil to HSS if you introduced 5-30W for gas engines. Please package you gas injector cleaner for larger ( 35 gallons ) tanks.

      Thank you for all the detailed feedback!
      We still recommend a half dose of Stiction Eliminator every 4th oil change (gasoline oil in the works, but may be awhile; same with larger size Gasoline Extreme bottles…thanks again!)

    Just placed a order Thursday of the 5w40 for my 96 f350 7.3l with 173,000 that’s had nothing but 15w40 Rotella or mobile delvac, switching to full synthetic for longer change intervals, don’t know anything about yalls oil but figured I’d take a shot at it to see how it is, Hope it’s worth it

      in mixture with green diamond 5w40 full synthetic engine oil engine runs smoother so far and cold starts are times better, also bought blue diamond severe duty automatic transmission fluid to go in my ZF5 I can tell a slight difference in smoother shifting when shifting, about to change the rear diff fluid and add FR3 in the gear oil and change out power steering fluid and add in FR3 with it also, only time will tell with all 4 together
