RE: [Chevelle-list] Royal Purple oil

[Bill Vander Werf]

I didn’t really notice any difference in idle speed. The car has gotten progressively quicker though. I think tuning and weather has more to do with that than the oil though.   Yes I am the one that was eating thrust bearings. Polishing the thrust face was the answer. So far the car has gone a best of 11.53 @ 115.41 on motor.   I did have to lower the idle about 100 RPM on my Harley after switching to Royal Purple.   Bill Vander Werf     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob n Cheri Sent: Friday, February 06, 2004 10:39 PM To: The Chevelle Mailing List Subject: Re: [Chevelle-list] Royal Purple oil   Bill, Thanks for the reply. Did you notice any changes with the Royal Purple oil with respect to idle speed? What about performance? E.T. or trap speed? Also weren't you the one with the 454 that ate thrust bearings? As I remember the solution was polishing the crank thrust surfaces and no more problems. Bob
