burning transmission fluid, 12v Cummins?

need to know if anyone has successfully done this without damage to motor. AT is sometimes recommended to clear out injectors.

these guys have ran their Ford powerstroke 25k+ miles with no problems. that's running either 50/50% and/or 100% tranny fluids.

got a reliable source of AT fluids. 30-40 gallons every two weeks. sure would be nice to reduce my fuel costs....

soooo... has anyone ran AT successfully with 12v cummins?

 

Ive heard a lot about running ATF with good results but when you think about all of the added friction modifiers that are in ATF it seems unwise to add it as a fuel additive, let alone pure fuel.
Ive read claims of all kinds hailing ATF but I dont know anyone personally who has used it so I dont even think about it.
Can you also get used oil from this source? If you could get used oil, petroleum not synthetic, at 30gal a week that would be a safer bet. Just filter it and get ready for some thick clouds of coal. A mixed blessing.

 

Not in my truck!

Run some bio and get your system cleaner. ATF will eat out the pump and injectors. Not worth it. This comes from the 50's when injectors were like garden hoses and we pumped bunker sea oil for fuel.

 

Never.......old school thinking. Newer ATF has too many additives which don't burn well. I know a guy who has forgotten more about diesels and trannys than we will ever know. Even with his access to all the free ATF he could burn, he wont.

 

no trans fluid, friction modifiers= more friction on metal parts= not good, if anything motor oil filtered really well ( like 5 coffee filters stacked) should be o.k. maybe like a every 9 gallons of diesel with 1 gallon of motor oil. feel it out but i would run any more than that.

 

Don't know if i would do it in my cummins ... But years back I had a VW rabbit pickup truck and it had a 9 gallon tank . Plus a buddy who ran a quick lube place ...I had a unlimited supply of ATF ...I was was buring 4 gallons of strained used ATF and 4 of diesel , that thing ran great ...the BTU factor is much higher than diesel or even Karo .
I did notice some extra smoke but besides that it worked fine ...I did that for 2 years and 30k miles .
I am older and know a little more ... But it will work .

thank YOU! this is the type of info I'm looking for.

every one keeps on saying friction modifiers, but what does that mean? not sure if I buy that reasoning...

considering buying an old beater first gen for $2,500 to try this out on.

this would be sooo much easier than collecting grease. all I have to do is put an aux tank on my truck. to collect ATF (with two inline filters), pull up to storage ATF container then transfer 50gallons or so.

then pump into main tank what ever amount I want into my main tank to mix with std diesel.

 

Friction modifiers REDUCE friction, not increase it.

Fact, when I had my 95 Cummins EVERYTIME I added 1/2 a quart of ATF to a fill up, it got better mileage. About %10!! Blast away, but that is what that motor liked. I never tried a higher ratio.
My 02 doesn't do that, not sure why.

 

Everything I've read on this site indicates that using ATF with our pumps will destroy the pump. You'll have to burn a lot of fluid to account for having to buy a new pump prematurely. I'm not about to chance it!!

 

Modern ATF is 60% additives, most designed not to burn, that will leave damaging ash deposits in your engine.
ATF's use as an additive comes from the old days when it was nothing more than light oil similar to hydraulic fluid.

 

if friction additives reduce friction. this would be better for our fuel pumps.

no clue about extra ashe generated, but our 12v have a reputation for burning just about anything. good grief some folks run straight used veggie oil.

wouldn't even consider doing this with a electronic fuel pump setup.

really surprised no one with a 12v has stepped forward with first hand feedback about running ATF.

 

wooo hooo... finally found a butt load of info!

went to 4btswaps.com http://4btswaps.com/forum/showthread.php?t=1200&page=3

I would be a little leary of this. But it is amazing what a diesel engine can do.

 

no way I'd do this with any late model CTD's, only 12v
seems newer the model, more sensitive fuel system becomes.

point was driven home in recent thread about taking a new CTD down to south america. his system jammed up in short order.

 

When I run ATF as an additive in my 96 12 valve, I notice throttle response is better and it idles smoother.

Friction modifiers reduce friction.
