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.
  • I4 needs 6 quarts for a complete oil change.
  • V6 needs 5-6 quarts for a complete oil change.
  • V8 needs 5-8 quarts for a complete oil change.

Please Note. If you are unsure how many quarts of oil you will need for a complete oil change, please refer to your vehicles owner manual or contact your local Ford dealer.

          Bang bang

          I could really feel a little increase in power when I used this. Royal Purple is the best motor oil out there. Hands down!
