Guys, we just got word from an inside guy at GM about this!! GM cut-off their supplier of the EOS because the supplier would not make it to GM's spec any more. GM is "frantically" searching for someone who will make it to their spec again however! It will be back as soon as they can manage this!!!

And FYI, Redline is NOT one of the oils we recommend that have the high levels of zinc/phosphates. We've seen engines broke in with similar oils to theirs that after less than 1000 miles, look like they have 100K!!

Street Legal Oil Boost, a.k.a., SLOB, is cheap ($1.99 a bottle) at Big Lots and is loaded with Zinc. 4898 ppm according to this analysis:

And it isn't thick like STP. I add it to 5w-30 syth in my 71's engine to protect the flat tappet cam.

I am headed out right now to buy all the EOS I can find...

Seems the new CJ-4 version still has a healthy shot of zinc:

... and they also have it in a 10w-30 for those that want a thinner oil:

For those who need ZDDP, it seems that the OES from GM is back.

And FYI, it is still a "future" part with GM and cancels upon ordering. I'll do some checking today to see if we can get any realistic ETA.

I went out and bought a case of the GM EOS while I could find it.

BUT for those who cannot find it (GM EOS) now, try this... I hope the mods do not get mad about me linking this... I do not think there is a competing vendor here...
