...but I had multiple injector failures when I filled up with only Chevron over the years...too often for my liking. I switched to Shell and 76 and haven't had a problem since. Am I crazy? Definitely...but I've heard the cleaning additives in Chevron are too abrasive on the injector coil insulation. This is all heresay, but I abide by it 'cause it seems to work for me.
