So yesterday i was going back and forth with a really reputable engine builder on Facebook, the guy is a very experienced engine builder who specialises in building very high horsepower Turbo Ford Cologne V6 engines, he's been building them since the 90s and he said to me that he noticed the engines that had been run on full synthetic oils had more cylinder wear, despite being cleaner and having less Turbo issues.
I was really surprised with what he said, what do you think?
