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.

    15w40 full synthetic in 2015 f350 6.7

    Andrew (verified owner) –

    I noticed a difference right away as I have in all the vehicles I have put this in. The engine spins freer and I’m up between 1 and 1.5 mpg average on my work commute. My truck is a CC/LB 4×4 with 35 in tires. I just completed a 100 miles round trip freeway run and averaged 18.7 mpg. I was at 19.5 mpg before the exhaust filter went threw it’s cleaning cycle. The best I’ve seen before using this oil was 17.5. The only down fall is needing a better way to put the oil in the truck from the jug.
