Inside view of our trailers...  The trailers are all equipped with a full line of oil filters for most cars and trucks, wiper blade, air filters and the oil vac system to allow for the use of oil extraction via the dipstick.  This extraction method is most widely used in the use of oil changes on boats to avoid any oil leaks into the water. The double walled tanks with 50 foot hoses and oil dispensing guns are used to accurately measure the exact amount of oil that is needed for each specific vehicle.
