The only time I have seen someone put ATF in a diesel is when the guy accidentally filled it with gasoline. Basically a new knuckle head driver took one of the trucks to the gas station and literally gassed it up. Luckily he was smart enough to call the dispatch and they got one of the old hand mechanics on and he said add two quarts of ATF to the fuel tank and bring it strait back to the shop to be siphoned out.

Back in the 1980's I worked for a trucking company and we always filled new fuel filters with ATF, but that was the most we ever add. Whether this was a good idea or not I'm not sure, but the +300 trucks the company had and we service got it everytime.
That said I would not do it on a newer computerised diesel like the Chevy/GMC Duramax or the newer Powerstrokes.

I've got a couple of gallons of used brake fluid (DOT 4 mostly), some old power steering fluid, some used carb clearner solvents, and some used battery acid, but I don't have any used ATF.
Which of these chemicals, if I filter them through a cheesecloth to remove the big chunks, are good to recycle through my RV's Mercedes diesel engine, or should I just dump them all into my tractors fuel tanks?

Save them to start the fire to burn all those old tires. You might not want to filter the acid since it might destroy the cheesecloth.
What?---- I thought if I toss the cheesecloth reminants into the tank it would function as an extra fuel filter.....

Why dont the OP just give it away? Or save it for a LEAKY transmission? He could give it to me i use a quart out of my leaky sealed ranger every few thousand miles or so.
Never put "Type F" in anything but a ford transmission!!!
Type F has " grit" in it. Will wipe out a diesel pump.

Don't forget that the cheese cloth can still be wrung out and used to make cheese...:confused2:
(yeah, I know you're joking...me too)
Ray66V -- I read your link. Thanks, lots of good stuff there. It looks like 2 cycle is good for the diesel fuel system. The ULSD caution seems to be only for engines that have a DPF. Interesting how simple 2 cycle beats the addition of other chemicals that are rated for improvements in lubricity ! I mean, ?? Didn't they check if FPPF Lubricity Plus Fuel Power makes it less lubricious? Guess I'll continue to use 2 cycle oil in the diesel with more confidence.

in the late 90's i was a motor pool mechanic with 25 hummers running 6.2 diesel engines, and oh what poor things they were. We added half of a coffee cup of ATF every fill up. It worked great, and helped. Later they told us that they changed the chemistry and it did seem to quit working
An old timer said of coarse they would change it, why sell 99 cent ATF when you can sell 4 dollar additive
old diesels seem to like it, newer one don't.
I sure would hate to have problems in a new hot **** tractor due to ATF in the fuel, but would dump a snort in my 85 Kubota any day

A friend sent me an email saying that a 50-50 mix of ATF & acetone makes for a great penetrating oil.
