Hot Shot’s Secret has expanded its Green Diamond Fleet Full Synthetic Group III/Group IV engine oil line by rolling out a new 10W-30 blend.

Specially formulated for use in diesel powered vehicles that experience extreme temperatures, heavy loads, stop and go operations, or high airborne particulates, Green Diamond Fleet is ideal for all diesel-powered light-, medium-, and heavy-duty trucks, agriculture, construction and industrial equipment, RVs, drilling rigs, and stationary engines. As a severe-duty diesel oil it is a replacement for any CF-4, CJ-4, CI-4, and CI-4 Plus specification oil.

Manufactured strictly from Group III and Group IV base oils, it is infused with Hot Shot’s Secret FR3 Nano Technology and a fully formulated CK-4 additive package. This 100% synthetic diesel oil effectively cleans, lubricates and maintains engines and turbos for long-lasting protection, improved performance and fuel economy and longer oil drain intervals. Additional benefits include improved cold starting, reduced soot, noise and vibration.

Hot Shot’s Secret 10W-30 Green Diamond Fleet Oil provides enhanced oxidation and thermal stability to prevent deposits and premature oil breakdown, according to the manufacturer. The FR3 Nano Technology ensures increased film strength for reduced shearing and friction, allowing for improved protection and longer drain intervals.

Green Diamond Fleet also meets the requirements from Ford for added wear protection as stated in Ford Specification WSS-M2C171-F1 and exceeds API CK-4 specification. Not all CK-4 specification oils meet both the CK-4 and the Ford specification.   

Green Diamond Fleet 10W-30 is available in either a 1 gallon or 5 gallon container, as well as in bulk quantities. Other Green Diamond Fleet blends include a 5W-40 and 15W-40 full synthetic, and a 15W-40 semi-synthetic.
