If that is who did the oil change last, tale your vehicle in as if nothing has happened. When they say they can't remove it, pull the receipt from the globe box. Watch them though, to make sure they drain it. I never trusted cheap labor ... Or even the expensive one, for that matter, but 17 year olds messing with my car ... How much training they received, i wonder sometimes...The bolt looks to be fine I had the oil changed 3 months ago at jiffy lube for convenience (I drive a lot) the head is fine ratchet has no problems grabbing the bolt and there is very little rust on it. is it possible that jiffy lube simply over torqued it?
Would spraying something like wd40 on it help?
