This is an old diesel mechanics trick born about a thousand years ago when
the injection pumps were all mechanical and we were moving away from sulfer
in diesel fuel as a lubricant. The older pumps were having a problem with
lubrication with the lower sulfer fuels. However, with the newer pumps
designed for lower sulfer levels, and with computer controls monitoring
emissions, adding ATF to your fuel is an idea whose time has passed. If you
really think you need something, just buy a quart of good quality diesel
fuel treatment (something that prevents gelling, kills bacteria, helps get
rid of water, and boosts the cetane level) and add 4-8oz. to every full
