Green Diamond Fleet 15W-40 synthetic oil can be run over 60,000 miles, as long as the oil is kept clean and monitored every 6,000 miles for TBN number.

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 and 10W-30 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.

Hot Shot’s Secret Green Diamond Fleet Oil is great for:

  • Fleets
  • Construction
  • Drilling Rigs
  • Heavy Duty Trucks
  • New Passenger Car Requirements
  • Gasoline and Diesel Engines
  • Turbo/Racing Engines
  • Arctic Service
  • Agriculture
  • Industrial
  • Stationary Engines

No other diesel oil or fuel additive has a better guarantee than Hot Shot’s Secret products. If our products do not deliver as promised, then we will give you your money back. End of story.

    4 out of 5 Oil for the long haul

    Andy Wood (verified owner)

    Green Diamond provides the protection my engine needs to perform daily. With over 500K miles it needs more than just conventional oil.

    5 out of 5 Good stuff

    Bill Helmick (verified owner)

    First time using it I am running it in my stock Titan xd 5.0 cummins and I swear the engine seems to run much quieter and it looks like I picked up 1-2 mpg.

  4. Question

    Kenny M Wilson

    My 01 Frtlnr has a 600hp cummins isx engine . I’m considering changing from Delo 400 to your green diamond full synthetic. What would be my benefits if any ?

      Hi Kenny, they are both similar/great oils. However, the biggest advantage of our Green Diamond is our FR3 Friction Reducer already blended in. For extra mpg and horsepower up to 5%, reduced engine wear up to 43% and more!

      Thanks for your answer and my plans for my next oil change is to switch to your product. Before I do , which blend do you recommend , The blue or green . I’m asking because I value your opinion , and you’re supposed to be the expert.

      Hi Kenny, for the best results and value we recommend using the Green Diamond first, followed by an oil analysis. This will provide more clarity on the specific needs for your engine and driving habits long-term. Hope that helps!
