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).

At Hot Shot’s Secret®, we infuse our oils with FR3 Friction Reducer® due to its exceptional performance-enhancing properties. FR3 Friction Reducer® is specifically designed to reduce friction and minimize wear within an engine’s moving parts. Oils with this advanced friction-reducing technology provide superior lubrication, creating a protective barrier between metal surfaces and reducing metal-to-metal contact. This results in reduced friction, lower operating temperatures, and improved fuel efficiency. The infusion of FR3® also helps prevent premature engine failure by minimizing wear and tear on vital components, such as pistons, bearings, and camshafts.

By incorporating FR3® into our oils, we offer a superior product that extends the lifespan of engines and other oil-lubricated components, minimizes maintenance requirements and ensures peak performance and reliability. Hot Shot’s Secret® oils maintain their performance for longer periods, extending oil change intervals and reducing overall maintenance costs.

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.

    Best of the Best

    I’ve been using HSS products for years. I’ve yet to try their oil until recently. All I can say is wow. Made my 2017 6.7 Scorpion run a lot quieter than T6 with FR3. This oil is their fleet edition and I’m sure their blue and black diamond is better but I don’t plan on running my oil for extended periods. To be honest, nobody should even be looking at any other oil. There is no other oil that can touch this stuff for the price.

    This is my first time using green diamond oil. I chose this product after visiting with the staff about which oil I should use in conjunction with the stiction eliminator to help with the initial clean-up of my engine.

    I have used Stiction Eliminator and EDT for several years in my 6.7 Cummins with great success. I couldn’t get Rotella at my local oil change facility so I ordered the Green Diamond to try.
    I only have about 1000 miles on the oil but engine seems a little quieter.
    Price wise about the same as Rotella.
