Proper maintenance of your vehicle goes a long way toward prolonging its life, and cleaning the oil tank is an important part of that maintenance. Of course, changing your oil regularly is important, but cleaning your oil tank also needs to happen on a regular basis, before sludge is allowed to build up and keep your car from running properly. Once you have learnt the process, it is relatively easy to do.

  1. 1

    Drain your oil tank by opening the valve and catching the oil in a bucket. Spray the inside of the tank with water until it runs clear. Dispose of the oil with your local mechanic.

  2. 2

    Put the drainage cap back on and open the main filler. Pour a solution of 1 cup trisodium phosphate (TSP) to 5 gallons water into the tank. Leave an air hose turned on inside the tank for approximately 12 hours. The air hose will shake up the solution inside the tank, which helps break up any residue inside the tank. Drain the tank again and dispose of the solution in your toilet or drain.

  3. 3

    Pour 1 to 3 gallons denatured alcohol into the tank. The alcohol will help to dry out the tank completely. When pouring alcohol into tank, rotate the alcohol so that it coats more area inside the tank. Leave to air dry or use the air hose once more to dry out the inside of your tank.
