Default GM EOS Reinstated

And, btw, GM reinstated their EOS. I have not seen a VOA on the new stuff as I still have a case of the old stuff -- so I can't tell you that I'm 100% sure that it's the same. But I'm sure a VOA will turn up on BITOG soon. Here's a link to the new stuff: http://www.gmpartsdirect.com/results...partnumber=EOS

I didn't know that GM brought back the EOS. Some more good info. Here is the ZDDP Plus info http://www.zddplus.com/

To ensure the oil has a sufficient percentage of ZDDP, one good way you can do it is purchase Joe Gibb's oil . . . very pricey . . . or Brad Penn, which is refinned from Pennsylvania crude. Both have sufficiently high concentrations of ZDDP to protect your flat tappet cam. Gibb's oil is expensive, but considering the cost of rebuilding your engine . . . Brad Penn can be had for a "reasonable" price. Either way, good oil costs less that a wiped cam lobe. I follow the "Pay me now or pay me later" rule.

Brad Penn web site: http://www.bradpennracing.com/News/june192007.html

Joe Gibb's oil is another they mention by name in the article.

Redline is about to market a synthetic with ZDDP and other anti-wear additives soon.

Who has used this additive? Probably difficult to know whether is works until many miles. Is the Zddplus available only from the website?
