I know ester based oils will provide the best heat stabilization, yet in my experience with Redline it seemed that it didn't suit my application as well as I would have liked. I got some unpleasant liter chatter on the cooler mornings. And it's obviously not readily available in my area. So in short I switch back to what my GM dealership provides. With our ACDelco bulk synthetic we have at work I don't have that issue, yet I'm not really sure how true this "bulk" oil is.
