Hi DH,
Read all pages here as I am trying to figure the oil in my 2013 10k mi z06 stock heads. DD, cold starts, autox 1x mo. New to me unknown oil now, assume dealer serviced. Used RL 10 yrs in my ls6, excellent. But, this is ls7 with it's own "characteristics".
So read all 20 pgs, long/short going with M1 0w-40 & will get old oil Blackstoned and will pull a sample of new @ 3k mi. Wish me luck & THANKS for all this discussion/info!
