A common practice with many diesel heavy equipment owners is to add 1/4 cup of transmission fluid per 150L of diesel to keep their diesel semi's or equipments fuel pump lubricated and engine carbon free.

Myth or real benefit is what I am curious about, and is it ATF or type F fluid that works best ?

Since I have a tired old diesel fuel pump ($1800) I am going to start adding trans fluid to my fill ups to lube the pump , not sure if it will actually clean carbon but lubricating the fuel pump sounds probable to me..

for my fill ups of 55L i will add 1/10th a cup / 25ml of ATF
