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 Shot’s Secret products. If our products do not deliver as promised, then we will give you your money back. End of story.

    Great oil

    Hyrum baumgartner (verified owner)

    This is by far the best oil for the price, truck is smoother ,quieter and will go longer between changes. Only oil I will use in my 16 f350 diesel

    Great diesel oil

    Used to use the Blue Diamond until it was out of stock. I switched to green diamond, and I’m really encouraged with my oil test results. Will definitely keep using this product in my diesel truck. I’ve been using HotShot products for years, really pleased with all of them!

    Great Lubricants

    I have been using HSS for fluids and additives for over 100K on my F250 6.7 Diesel and it has been great. HSS customer service has been spot on as well!

    5w-40 green diamond fleet oil

    Mitch Race (verified owner)

    Seems like great oil. I used this on the first oil change for my new 2022 f250. And so far it’s running great . I feel at ease knowing I have proven quality oil in my engine. It would however be nice if I could get another 10% off on my next oil order.
