Filling her back up is quick and easy through the Fitzstick...8 quarts went down with a 12v pump in under 30 seconds...look closely at the bucket level and you'll see it drop before your eyes...
I've always torqued my own lug nuts down to 95ftlbs...retighten 3 times after initial torque down and never have to worry about them till I take them off at the next rotation...never used any lube...
I'd gone back, tell them they over torqued the lugs and have them take the wheels off...if they can't and/or break the studs, then it's on their dime to repair...
