And 500,000 miles, have you been under the valve cover? If this motor has been subjected to synthetic and extended oil changes, the oil brand may just be the least of your worries. And while you are in there, run an overhead.
Thanks, you stated what’s my biggest worry. I miss stated my actual question is it OK to switch oil I’ve always heard you need to stay with one oil. Didn’t want to start a new thread over something so trivial. But I was worried about the overhead and cam issues. Thanks
