I will see if he will do more frequent oil changes and maybe go up to 5W-30. He was going to sell this one when it was fixed and buy a new one but he just got laid off indefinitely from the railroad so I think he has put any large purchases on hold for now.Yes thanks for the update. He should prob do 5k oil changes from now on with an older, high mile engine like this. Esp with cheaper timing chains in it. If it were mine I’d use MC 5w30.
