There is not an additive specifically designed to remove water from diesel fuel. However, a number of additives can be used to improve the performance and emissions of diesel engines.

Red diesel is made from a higher quality oil than regular diesel. It has a higher octane number and is used in engines that require a higher compression ratio.

If your engine is an inline six-cylinder engine, you will need to remove the oil pan. On engines with a V8, the oil pan is located on the front of the engine. Use a large screwdriver to pry off the cover. Wipe down the inside of the pan with a clean cloth or a paper towel. Pour enough fresh, cold oil into the pan to cover the bottom.
