I've never had a single problem when I take my cars to a Jiffy Lube for just an oil change. $95 bucks for the same oil change is just rediculous. And wanting to save money on maintaning our MB does not mean we are cheap. Being able to afford these cars does not mean you have to spend like crazy. Some people like myself are able to afford 2 MB because we are smart with our money.
Consider yourself very lucky so far.
I have seen numerous cars come in the shop after something being damaged or left loose, or not put on right, or not put on at all! from Jiffy Lube and other quick lube joints.
Matter of fact, my brother in law came over to my house the other day after having his astro van at Jiffy lube for an oil change.
As soon as he hit my street, he heard a loud POP! then as soon as he hit my driveway his oil light came on.
Sure enough, he lost all of his oil coming up the street into my driveway.
I looked underneath and found his oil filter totally missing.
We walked down the street and found it on the ground with no gasket on it.
The only thing I can think of is that it may have been double gasketed and the tech did not peel off the old filter gasket.
Luckily, I have an astro myself and had an extra filter and oil in my garage.
I am a little embarassed because now I have a huge oil slick in the middle of the street leading right into my driveway where my Dodge Dart is parked, and everyone probably thinks my Dart is a big piece of crap and caused it all...LOL!
