Some people on the other forum are supposedly running ATF. Do you think that it is safe. Here are a couple of discussions on this topic

Anyone running atf as diesel fuel?

--------------------------------------------------------------------------------

I've heard alot of people talking about running used, filtered atf as fuel. Some are running 8 gallons per 30, some 15 gallons per 30 and one guy I talked to said himself and his buddy run 100 percent. Anybody have any long term experience with this? One person I talked to said he has run it for 5 months now and only has noticed more smoking out the exhuast as the only down side. All but one are Cummins and one a 7.3. Thanks.

Well I have found out that 5.9 Cummins and 7.3's run great on 3-1 mix and ok at 50-50 after talking to about 10 people. Just don't know about possible long term problems with running stronger mix's than 3 or 4-1. I also was informed that at 3-1 mix with a tune installed, you lose some smoking at WOT which is a bonus. It seems the atf might burn a little hotter helping combustion. The only failure I've been informed about was an in-tank pump failure on a 5.9 but the guy told me he was running no less than 2-1 and sometimes 100 percent atf and it also had 150k on it so it may just be a normal failure?



hmmmmmm makes me think

 

If you are insterested here is the link for the discussion

Link removed due to profanity

 

One think to consider, it's red. Red fuel in your tank can get you a hefty fine. Untaxed off road fuel is dyed red. Most likely more than what you'd save on fuel costs. Plus I don't think running it through a $1800 injector pump is a good idea. ATF can be very abrasive.

 

Don't even need to read the link to be comfortable saying........ That's dumb!

ATF is not made to be burned. It does not burn like the ATF of many years ago. It is very abrasive and will do more damage than good.

 

I know a couple of guys with 1st gen trucks who have been running several gallons of ATF per tank for over 5 years with no problems. I dunno how well the 2nd and 3rd gens would deal with it though.

 

I used to run it in my GMC truck, but I would not dare run it through a vp-44

 

It'll run but you won't be doing any good for the truck. From what I hear it's actually bad for it. The way I see it, 2-stroke oil is meant to burn so it combusts well. Motor oil not so much but is still forgiving at lower concentrations. ATF was not designed to burn and actually the opposite.

 

Years ago (more than 30) we used to use ATF in the big rig diesels. It worked very well back then. Gave more power and fuel mileage. Things have changed dramatically since then in both the ATF and fuel systems. I wouldn't even consider it now.

 

It might now be made to burn, but just put a quart in your wood stove and light it. It burns great, I use it to start the fire all the time.

 

And here I thought we were talking about diesel engines burning ATF and not about burning ATF in someones wood stove!

 

Easy way to tell how well something burns if to heat a tablespoon of the fluid, whatever it may be, with a propane torch till it starts on fire. When it all burns away look at what you have left. My bet with ATF there will be a bunch of ash. With gas or diesel there with almost nothing left in the spoon.

 

Oh, I so wanta be there when you take a propane torch to a tablespoon of gas! I'll be standing over there..... wayyyyy over there!

 

The gas isn't the problem, it is the fumes. Stand back, I can see hurt written all over this.

 

Just speculation.....but I imagine after a long period of use the engine is going to coke up. Viscosity is another issue. These engines are made to run on fuel of a certain viscosity and specific gravity. I like the idea of this topic but these engines are too expensive to replace and at some point the 12 valve is going to become a rare bird. Now a Volkswagon or old Mercedes IMO would be worth using for that purpose.
