Royal Purple 15w40 Motor Oil

Protect Your Investment. The most effective way of ensuring long engine life in either a heavily modded racecar or daily driven 'Stang is regular oil changes. And there is no better oil available for your Pony than Royal Purple. Royal Purple is a full synthetic oil that contains a patented additive to reduce engine wear and protect your rings, cylinders, and bearings more than any other. It also sticks to your engine's internals after shutdown to protect your engine upon startup.

Superior Performance. Unlike other oils, Royal Purple continues protecting your engine even at high temperatures, making it a great choice for every Mustang. It lubricates better regardless of temperature, ensuring your Mustang will run right whether you're stuck in a traffic jam or going for FTD (fastest time of the day). Many Mustang owners even report better throttle response or even horsepower gains with Royal Purple.

Resists Breakdown. Royal Purple is more resistant to breakdown than other oils, meaning you can go longer on an oil change without worrying about engine damage.

Application. This Royal Purple Oil is a 15w40 weight that is intended for Racing Applications. Check your Mustang's oil cap or owner's manual for the correct weight for your engine.
