I’m in a discussion with a guy about octane and towing. Up until last week, I had a 2015 Silverado with 5.3 Direct Injection. When I would tow my Chevelle in my 24’ enclosed trailer, I would run high octane because the engine is working harder.
I realize the timing will adjust to prevent engine knock but my thought, and the way it was explained to me, is that the higher octane will prevent detonation. If that’s the true, the timing won’t back off which in turn will help prevent power loss.
Am I way off........too old school???
