Mike Jones street rep is low. keep going

I have royal purple in my car, I have the engine oil and the rear end fluid. I didn't feel any seat of the pants difference and I highly doubt there is any real gain.
I believe you should buy oil that is the best at luricating your car, not what you think will provide a hp increase.

I use it too, and according to some article (apparently it was gm hightech) it was 9hp from changing to RP engine oil, tranny fluid, and rear end fluid, in an ls1 car.

I've had it in my car for about 500 miles now and I really

couldn't tell a performance difference but the engine sounds alot better than it did. I only changed the engine oil though. Next time I'll do all the rest.
