You start a thread looking for a good place to get an oil change and then you mention you have been happy getting oil jobs at Valvoline?! Full of fail. If you have been taking your car to a Valvoline, you should not have a problem with other valovline, jiffy lube, etc locations. If you have a nice car then you shouldn't be taking your car to these places to begin with. But since you have, whats the problem??!
Happened to my little sister and her 2011 ford escape with 6000 miles on it. Ford Dealership didn't put any oil back into the engine. She drove it home and it died on the highway. they ended up pulling out a brand new engine from an escape on the sales floor and putting it into her car.
