Hi all, sorry to make some of you revisit this...:read2: after reading this entire thread I was just as confused as some of the others here. To make things simple, can one just use the "oil of choice" off the shelf at any Autozone, Napa, Advance, etc. and just add some GM EOS to help with the zinc issue?
If so, how much EOS is added per oil change?
The above seems like a simple solution to everyone's problem, get any ole' oil you want (any oil) and then swing by your local Chevrolet dealer for a bottle of EOS. No Shipping, No waiting, No worries.....
This is under the assumption the new EOS has the Zinc content we need??..Is this a good choice?
Ok, good info, thats for sure! But now I am back to looking for an off the shelf oil that will not damage my engine. I have always used Valvoline Racing 20w50 in all my cars. This is the stuff off the shelf at Autozone. The bottle does not say Off Road or anything like that. From reading this thread it used to be a good oil but now the zinc content is a lot lower. Has anyone come up with a decent off the shelf oil they can post here that is readily found at an auto parts store that is ok to use?
Okay, this is what I've used for a few years now. Valvoline VR1 10w30 with 1/2 bottle of EOS to be on the safe side going into a BB with a lumpy cam. I ain't going to get into it any further than that, Sorry.

got rotella in my 340 right now to break in, but also added the comp cams zinc additive
have a case of Joe Gibbs oil to change once broke in
but will probably run something different once that is gone and just use the additive. one bottle per oil change at $12 a bottle seems like the way to go
No kidding.
There isn't a ''one size fits all'' answer to this question.
mullinax95,
Do I mind? Ask a gear-head to talk about his engine? What is better than this.....
I have used two blocks - both are 340 resto blocks... one is siamese but if you didn't have the sonic test sheets I don't think you can tell the difference. At least I can not tell from the pictures.....
