How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

Description

Hot Shot's Secret Green Diamond Semi-Synthetic 15W40 diesel oil delivers optimized performance to ensure your vehicle stays efficient and is trouble-free for long-term use. Green Diamond Fleet 15W-40 is a synthetic blend of Group II and Group III base oils. This blend incorporates our patented FR3 Nano-Technology and CK-4 additive package to provide unsurpassed levels of cleanliness, longevity, fuel mileage and horsepower. Green Diamond Fleet 15W-40 was formulated to meet severe operating conditions such as hauling heavy loads, stop and go and operation in areas of high airborne particulates. This oil is a fully formulated CK-4 motor oil with high detergency, exceptional oxidation and thermal stability that prevents deposit formation and oil breakdown making longer drain intervals possible. In addition to exceeding the API CK-4 specification, Green Diamond Fleet Semi-Synthetic 15W-40 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 specifications.

When you need trusted supplies to keep your engine running strong, Hot Shot's Secret diesel engine oil offers high performance to meet your essential requirements. This solution focuses on meeting critical vehicle needs, such as reduced maintenance, so auto owners can get more value from their investments. FR3 works by filling any microscopic irregularities in your machine components, helping to minimize metal-to-metal wear and tear in the vehicle's moving parts. The reduced friction decreases maintenance and repair requirements and enables you to get more prolonged use from your engine and individual mechanisms inside it. Meanwhile, the reduced friction also lowers the oil operating temperature, which can cut down on corrosion, overheating and otherwise overtaxing your vehicle and engine. The CK-4 specification is backward compatible with CJ-4, CI-4 and CI-4 Plus specification oils.
