A true PAO oil stands in a category of its own above all other synthetic formulas. Hot Shot’s Secret 5W40 and 15W40 CK4 specification are 100% pure synthetic using only Group IV and Group V base oils.

The 5W40 and 15W40 PAO CK4 are made of pure poly-alpha olefin (PAO) oils that require a very small amount of viscosity improvers to meet the weight specifications This allows the Hot Shot PAO 15W40/5W40 diesel synthetic oil to be loaded with more longevity and performance additives, keeping the oil cleaner longer and providing better mileage and horsepower.

The infusion of our patented FR3 Nano-Technology and CK-4 additive package provides unsurpassed levels of longevity and performance.

Blue Diamond oil is recommended for most diesel engines. The CK-4 specification is backwards compatibles with the CJ-4 and the CI4 Plus. In addition to the CK-4 specification, Blue Diamond PAO Oil meets the requirements from Ford for added wear protection as stated in Ford Specification WSS-M2C171-F1 (not all CK4 specifications meet both the CK4 and the Ford spec).

    5 out of 5 Best In Class

    Bought my first brand new diesel truck (F350) and after doing extensive research decided on Blue Diamond. Been using it after dropping the factory oil out of truck. I have a by-pass filter system (amsoil) on the truck and although I know I could run the oil for far longer, I still change oil out at 10K miles. The peace of mind far outweighs the cost. Keep up the fine line of products that you offer.

    5 out of 5 A true full synthetic

    I want a fully synthetic oil. Blue Diamond offers that. Not really sure what’s in other brands. They are not even claiming to be a true synthetic.

    5 out of 5 Extended drain intervals during warranty period.


    Should I take advantage of the extended drain intervals with this oil while my truck (2019 Ram Cummins diesel) is still under warranty? I do oil analysis every 5k miles. Also, if do eventually do extended drain intervals, how often should I replace the filter? I do not know of a filter that claims to last as long as 20 to 30k miles. I was planning on doing 20k intervals since my truck already advises 15k. 20k seems easier to keep track of and is better for the environment and wallet.
