    What exactly does adding ATF to diesel fuel do?
    Lubricate?
    Reduce black smoke?
    Cetane boost?
    Cleans fuel system?
    Just want to know for future referance.
    Thanks.

    All it does it help to increase the lubricity of the fuel. Non-sulphur diesel dries out seals and o-rings throughout the fuel sytem, and a quality conditioner is needed to keep things lubed up.

    I can't say for certain that ATF does the job properly. I also wonder what side-effects it could cause(ie plugged injectors). A better solution would be to run a quality diesel fuel conditioner such as Stanadyne.

    I don't know about your area ? Here where I live there is no need for a added lubricant in the fuel . Here there is enough sulfer for the pump to be lubricated .Check with some diesel shops where you live about your areas sulfur rates .I personally don't run a additive .

    It also turns the fuel "red" and will cause you to get a ticket that is out of this world if caught. Fuel that is dyed red is labeled as farm fuel which has no road tax on it. They fine you by the gallon you have on board and it can be as high as 10 thousand buck$. Some states, such as New Mexico have a little device that detects it, kind of like a syringe they put in the tank and draw it out.

    One last item: ATF can be used to diagnoise a failing injection pump. As injection pumps get worn they (usually) have a problem making pressure. If the engine starts fine when cold, then has difficulty when hot, (and a hot day for you Death Valley boys) the fuel is just too thin for a tired pump. A quart or two added to the fuel increases the viscosity enough to bring fuel pressure up and "pop" open the injectors. Not really a fix, just helps to confirm your suspisions before you tear into the engine bay.

    Yea....watch them people who check yer fuel!! If you get cought with red fuel..even if you can prove its ATF fluid...you still get a nice fine. I suggest Stanadyne Fuel Treament. It helps alot!!
