Thx all.. The oil change was a few weeks ago now. Each time he leaves for work there's a new spot on the driveway, probably about the size of a 28t cog. He had the oil change done at Mavis (mistake 1) because his buddy was also going there to get a tire leak fixed.
He says he stopped in yesterday and they gave him a verbal $1,500 estimate, but can't remember exactly what they said (mistake 2). I told him under no circumstances to go there for anything other than a tire repair, and then, only if Madison Tire was closed. My neighbor has a good mechanic, we're gonna bring it there for a look see.
