Royal Purple. Engine Damage In The Long Term?

TXSpeedDemon · 08-15-2011, 05:13 PM

I've used RP before in my turbo Mazda, didn't like it. Noticed harshness and engine vibration at high RPMs. Made me nervous. Also seemed to lose power although I have no dyno #s to prove that. Switched back to Mobile 1 and have had no problems.

In my Nissan I use Redline. I change it ever 5K miles (about every 9 months). Twice so far and now due for it's third. The previous two times the oil came out looking brand new.

I should also mention my car seemed to burn a lot of oil before using Redline. At the first oil change I gave her (around 1K miles) she was almost 2 quarts low. I didn't check her when I picked her up so it's possible she was just short from the dealer, but haven't noticed any significant loss after switching to Redline.
