Are you doing engine oil analysis? Have you done actual back to back testing on an engine dyno between the cheap oil you use and a quality synthetic oil (it is very expensive to correctly test engine oils…so much so that most people won’t do it)?
When you do some comprehensive testing you quickly learn quality oil is cheap and cheap oil is just cheap.
Why does he need to? If the oil he runs....or anyone runs "does the job" what difference does it make? Do I need to call your wife? Imma send her a baseball bat. You best straighten up.
