A true PAO oil stands in a category of its own above all other synthetic formulas. Hot Shot’s Secret 15W40 CK4 specification is 100% pure synthetic using only Group IV and Group V base oils.

The 15W40 PAO CK4 are made of pure poly-alpha olefin (PAO) oils that require a very small amount of viscosity improvers to meet the weight specifications This allows the Hot Shot PAO 15W40 diesel synthetic oil to be loaded with more longevity and performance additives, keeping the oil cleaner longer and providing better mileage and horsepower.

The infusion of our proprietary FR3 Nano-Technology and CK-4 additive package provides unsurpassed levels of longevity and performance.

At Hot Shot’s Secret®, we infuse our oils with FR3 Friction Reducer® due to its exceptional performance-enhancing properties. FR3 Friction Reducer® is specifically designed to reduce friction and minimize wear within an engine’s moving parts. Oils with this advanced friction-reducing technology provide superior lubrication, creating a protective barrier between metal surfaces and reducing metal-to-metal contact. This results in reduced friction, lower operating temperatures, and improved fuel efficiency. The infusion of FR3® also helps prevent premature engine failure by minimizing wear and tear on vital components, such as pistons, bearings, and camshafts.

By incorporating FR3® into our oils, we offer a superior product that extends the lifespan of engines and other oil-lubricated components, minimizes maintenance requirements and ensures peak performance and reliability. Hot Shot’s Secret® oils maintain their performance for longer periods, extending oil change intervals and reducing overall maintenance costs.
