Blackhawk Lubricants Raptor Series 4T 4 stroke high performance Moto/ATV/UTV is built to keep your engine going the extra mile. This 10W40 oil is a synthetic blend that's fortified with ester to increase protection and lower wear on components. It was designed to hold up under the most demanding conditions. Why? Because the last place you want your oil to fail you is when the stakes are high. It uses boron ester nanoparticles that bonds on metal surfaces that create a microfilm and enables it to enter extremely tight tolerances. In simple terms, the high tech features of this oil allow it to create a film on metal and reach every little nook and cranny for ultimate lubrication. All of this helps reduce wear, engine friction, adds enhancements in extreme pressure, operating ranges, and boosts the overall life of the engine. It meets or exceeds API SL/JASO MA2 standards. And the best part? It's made in the USA!
