a used Ford Sport Trac. While driving home with my wife and 2 year old daughter my wife was sifting through the receipts in the glove box. I asked her to find one with the last oil change on it. She did and when she told me it was done at Jiffy Lube. At the next rest stop I slid under the truck and found the drain plug finger tight. The only reason it didn't unscrew was the rubber washer on the plug. It was barely keeping contact with the pan.
