We prepared a 1:1 (50/50) mix of Oil Eater degreaser formula and water. It comes in a gallon jug, and we used nearly all of it. Tougher jobs could call for using straight degreaser to cut through the oil. Utilizing a spray bottle, we liberally soaked the entire engine bay. This included inner fenders, firewall, subframe, and steering components. Removing the front fenders and front suspension will net you even more admittance, especially to the outer framerails of the car. Degrease any areas that will be painted. Once it was sprayed, we let the formula do its job-waiting about 20 minutes-then resprayed.
