Add Hot Shot's Secret Black Diamond Outlaw 15W-40 Full Synthetic Engine Oil to your engine when doing your next oil change. Hot Shot’s Secret Black Diamond Outlaw Oil is the most complete diesel oil available. Not only is it 100% PAO synthetic, it also includes a robust Total Base Number (TBN) of 14, extreme-pressure additives (including zinc) and it is blended with our patented FR3 Nano Technology and additional CK-4 additive. This means Black Diamond Outlaw provides you with unmatched protection and performance compared to other oils on the market. The harder you run your diesel, the more protection you need, and Black Diamond Outlaw offers just that. With nearly 3X the amount of zinc mandated by API for the CK-4 specification, wear protection will never be an issue. Your oil will stay cleaner longer, protect against deposit formation and shearing and will provide an increase in horsepower and fuel economy up to 3% each.

Hot Shot’s Secret infuses the oil 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 the oil, they 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.
