I do 90 percent of all my mechanical work on all my vehicles... only a few times to my mechanic since I don’t always have access to a lift. On my families Diesel engines I do some work; but kinda hard if the cab needs lifted for major repair, which I’ve done, just time consuming...On all oil changes, I’ve always done by myself, regardless of vehicle. My neighbor had her oil done at a quick lube place and they completely overfilled the oil... there are several stories of these places messing up customers vehicles, hence I don’t trust them...
