How much to add and how often? Purpose of this EOS ? Must I purchase from dealership? Or parts Store or on-line vendor? THANKS.

Full info here . In a nutshell: From GM only, 1 cup (8 oz, ¼-qt) per oil change.

I checked online at the link given and it says that it was discontinued. I then called the local Chevy dealer and he sold me 4 quarts that he had on the shelf for $6.99/ each. What do we do when this is gone?

Oh, grand. Donno. Gimme some time. I'm having throat surgery tomorrow so it'll be awhile before I'm in shape to do any digging.

I don't want viscosity additives, so no STP.

I stopped by at my local Chevy dealer to inquire about the EOS. He had 7 bottles on the shelf so I ended up buying all of them. I asked whether it had been discontinued and the parts guy wasn't aware of that. Said he sells a couple of cases a year.

Valvoline Premium Blue 15-40 lots of ZDDP and can be used on break in without EOS.

If it isn't on back order, and if we do get it will it fit?

Get some STP and be done with it.
