Hot Shot's Secret Green Diamond 10W-30 Full Synthetic CK-4 is a 100% full synthetic heavy-duty diesel engine oil manufactured strictly from Group III and Group IV base oils, infused with Hot Shot's Secret patented FR3 Nano Technology and a fully formulated CK-4 additive package. It effectively cleans, lubricates, and maintains engines and turbos for long-lasting protection, improved performance and fuel economy, and longer oil drain intervals — with improved cold starting and reduced soot, noise, and vibration.

Exceptional oxidation and thermal stability prevent deposits and premature oil breakdown. The FR3 Nano Technology ensures increased film strength for reduced shearing and friction, allowing improved protection and longer drain intervals. In addition to exceeding the API CK-4 specification, Green Diamond 10W-30 meets Ford's WSS-M2C171-F1 requirement for added wear protection — not all CK-4 oils meet both.
