Hot Shot’s Secret Green Diamond 15W-40 Full Synthetic CK-4 Engine Oil

Hot Shot’s Secret Green Diamond 15W-40 is a premium full synthetic heavy-duty diesel engine oil designed for hard-working diesel trucks. This oil is CK-4 rated and formulated to help reduce wear, improve engine protection, and support longer engine life in towing, hauling, daily driving, and performance diesel applications.

We recommend quality oil like this because diesel engines run hot, carry heavy loads, and depend on proper lubrication to protect the turbo, bearings, camshaft, lifters, and other internal engine parts. Cheap oil can break down faster, especially under heavy towing or high-heat conditions. Green Diamond 15W-40 gives your engine better protection and is a great option for routine maintenance or engine service jobs.

• Full synthetic 15W-40 diesel engine oil
• CK-4 rated for modern diesel engines
