NOTE: With the current state of affairs affecting the entire world with fear of illness and the massive effect it’s had on the economy, we have diminished all importing of US goods unless absolutely necessary. Not out of any kind of fear, but in an effort to wait until the Canadian dollar improves so I can continue to offer the best possible pricing for top quality imported goods. You may experience prolonged delays for non stock items, but upon request, I will gladly expedite required parts. Thank you for your understanding and ongoing support

  • 5W-40 Green Diamond Fleet Oil is a 100% pure synthetic using only Group III base oils.
  • 15W-40 Green Diamond Fleet Oil is a synthetic blend of Group II and Group III base oils.

 Infused with FR3 Nano Lubricant Technology

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 15W-40 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.
