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:

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

    Been using using green diamond oil on my f250 since I bought my first diesel on a recommendation from a performance shop and I love it! It starts great when cold is quiet and has all the additives I need

  2. Question

    Lonnie Forrest

    When running the Green Diamond 5W-40 within my 2017 6.7L CTD – will there be any additional benefits from adding the proper dose of Stiction Eliminator?

      Yes, but ideally every 4 oil changes or so at the maintenance-dosage for the best value, thanks!

    I have been using Green Diamond Fleet Oil in my 2003 Dodge RAM pickup with the 5.9L Cummins Turbo Diesel. This oil meets all the requirements and is a good value. I will continue to use this product that comes from a company with good customer service.

  4. Question

    Wyn

    Is this suitable for use in small diesel engines? I have a 2.2 inline 4 that has never had anything but conventional oil and I’d like to give it some better protection.
