Question about oil
I am well aware that General Motors requires Mobil 1 on my vette. However, all of my mechanic buddies give their own opinion about Mobil 1. And some of them seem to think that Royal Purple is a much better oil to use nowa days. I guess they feel that Mobil 1 is an outdated oil and that Royal Purple is a much better alternative.
My question is. Should I just stick with Mobil 1 on my LT1 motor. Or is the hype about Royal Purple pretty acurate. All I ever plan on doing with my Corvette is cruise around town and occasionally do a donut in a parking lot

I'm all for sticking with OEM for important stuff like oil, although I've seen a post (maybe in the c4 faq's thread) claiming that any name-brand synthetic works.
What's the potential benefit of using RP oil? cost-savings? free HP?
I'm not familiar with Royal Purple, although I have heard the name. I figure that mobil1 is what they designed the motor to run with, and Lord knows I've wailed the snot outta my motor w/o any oil-related failures.
The smart-aleck in me wants to ask how many of your mechanic-friends are diploma'd chemical engineers? Ooops, was that out loud?

That doesn't make 'em bad people, ha. My dad's a tool & diemaker and he had a cartoon on his bench that said something like "Let's play 'engineer', you design something cool, and I'LL make it work!"

I have read several documents on oil analysis. I stand behind Royal Purple. That is all the Vette will get in it now that I own it.
And I DO have friends with Chem Eng degrees who say it is better than AMSoil or Mobil 1.

If all you do is cruise with the occasional flogging, it really doesn't matter. So long as you use a quality synthetic like Mobil 1 or Royal Purple, you're fine. The differences aren't big enough to matter, with your usage.
