Havoline was good oil even before the Chevron merger, now it just seems to be better--at least according to the numbers. I use it in my car 300,000 miles, my daughter's 90 Buick 3.3 250,000 miles, my mother's 2001 Buick 45,000 miles, my girlfriends 98 Jimmy 165,000 miles, my generators and lawn mowers. My Duramax gets only Delo 15W40. For our applications it's the only oil we need. Like us, it's a blue-collar lunch-pail worker, steady and dependable.
And for the record, I use the orange filer with no problems. Guess that destroys all my credibility.
