sorry to hear about your luck with = the jiffy lube type place. I work at an Auto dealer and I can't tell you how I = cringe when I see a jiffylube type oil change sticker in the window. I have had to = use my 1/2 in. air gun to get drain plugs out, cut all but the base of filters = off and then use an air chisle to get the resty off not to mention lots of = stripped threads and some even held in with bluegoo.Make lots of noise and you = will probably get what you want out of them. good luck!
