Ac Delco Eos?
« on: February 05, 2007, 07:24:26 PM »
Hey Alan,

I see some of you guys are recommending GM EOS for break-in.  I have some AC Delco EOS which I'm assuming is similar...seems to have lots of Zinc, etc.

Yep, that's the stuff they sell now.  Same formulation as before.   Although the part number is different than that sold in the USA, I think the only difference is 1 US pint vs. 500ml.

Here's the latest analysis:

Note the zinc at about 6000 ppm.  Regular oil is about 800-1100ppm of zinc.
