The Blastolene Special, also known as the ā€œTank Carā€ is a Randy Grubb custom. Its 29.3L V12 (from a M47 Patton) needed an oil change, so instead of draining its almost 70-quart oil capacity in the garage, he took it to Jiffy Lube. Thatā€™s right: Jiffy Lube. He got a pretty good deal on the service, too.
