I agree,do what the poster says.I have heard of an oil change place in my area doing this and they paid for a new engine.Plus most oil change places do not check fluid levels resulting in burned up rear ends and transmissions.Replaced a ring and pinion in a Durango,the oil change place at the dealership did not check the fluid level in the rear end.Same thing with a Ford F150 4x4 with the 5 speed,oil change place did not check the fluid level in the transmission which was burned up and the transmission ended up being replaced.
