My 2003 Cobra has been running great after this oil change. It's expensive stuff but good insurance on a high performance motor.

Royal Purple HPS 5w30 has been a fantastic motor oil in my application. I drive my car sparingly, but when I do drive, it is "spirited" and aggressive. Prior to running the HPS 5w30, I was a long time user of Amsoil and Castrol 0w30 synthetic.

6 quarts of HPS 5w30 later, my Saleen S281 is running quieter than it did on the previous fill of Castrol EDGE SPT. The car feels less sluggish and has a more immediate responsive feeling to throttle input.

Used oil anaylsis have shown this oil to give extremely low wear and even after 10K it shows a high TBN (better to resist acids) I would rate this oil excellent for high performance engines and extended OCI's.

I purchased Royal Purple HPS 5W-30 for my initial oil change for my 2013 BMW 335is over the performance BMW oil. It has been doing wonderfully on my daily drives to and from work along with pushing 100 to 130 mph. I will be purchasing more and continue to use this product.
