I needed this GM EOS for two new motors im putting together but couldnt find it anywhere but a GM Dealer who doesnt keep it in stock so i had to buy a whole case. Im willing to part with atleast a half a case if anyone with new motor who are getting ready to break them in or any engine builders out there. it cost me almost $120. for the case, so i guess for $60. a half a case or about $10. per bottle i will sell it to whoever needs it. thanks--PS> this helps break in new motors and new cams without alot of problems- never had a cam or motor failure when using this stuff-highly recommended.
