Buy Royal Purple 31530 HPS Street Synthetic Motor Oil 5W30 Pack of 6

Customer Ratings:

This is hands down the best oil I have ever used. The price is steep, but the benefits are worth the money. Extended oil change intervals and a bump in MPG.

I've tried various oils in my car and this is by far the best oil I've yet to run. I gained 6mpg on the freeway changing to this oil and my car feels smooth and strong like it should. I will never put any other oil in my car.
