After changing the tranny fluid in my truck thois weekend I got to wondering about mixing it in with the fuel. I kept it nice and clean, it wasn't burnt up or anything. Just one of those things a guy thinks about while sitting relaxing with a cold one after completing the job. By the way I used 20 qts of ATF+3 to make sure I got all fresh in it. Using Dens method. It worked great.

 

AFAIK it's not a problem. Cummins allows up to 5% used oil mixed in with the fuel. Just make DARN sure there is no abrasive particles in it or you could be looking at a new inj. pump.

Mixing tranny fluid with the fuel is not a good thing to do.

 

I dont see why not? It lubricates your injectors moreso. For example... if you have an injector sticking, which we had happen on a semi of ours, you'd dump in some DEXTRON 3(which was on sale) and she'd get rid of that skip. So, it doesn't hurt a thing.

 

Well I didn't pour it in this time. I do think I will get rid of the old engine oil like that next time though.

 

Might be a good idea to filter the tranny fluid first My .02

 

I've always mixed tranny fluid with diesel and gas. Not used, but new, it helps lubricate internal parts and mainly breaks carbon loose from the combustion camber. Doesn't help much with newer motors, but tune up in a can in old motors.

Pour a small stream into the carb of a gasser while its idling at operating temperature and it really cleans the internals out and gives more power.

 

I'd like to do that too, add a quart or two at each fill up but filtering it is a major problem. You would need some kind of pump to recirculate it through a low micron filter. Seems like it would not be cost effective.

 

You guys are nuts! The fuel pumps in these things are cooled by circulating raw fuel in and around the whole electric motor. ANY metal paticals in the used fluids are going to attach to the permenant magnets and shorten the life of the LP, not to mention the IP. The filtration most of you are talking about is a shop towel over a funnel. This is simply not enough. You'll need to filter the used fluids lower than anything you can get at Walmart. This is not a good idea. What are you trying to save?.... at the cost of your LP, IP, or motor? Just plane DUMB!

 

1st gens have no electric fuel pumps.

All mechanical.

Still I wouldn't mess with it myself. Take it to the recycler and get rid of it.

All that clutch lining material cant be too good for lubrication.

 

Just my opinion mind you... but..... I would not recommend it...
No matter how many truckers swear by it, trans fluid was NOT meant to be burned, either as a fuel or fuel additive.
The byproducts (which I can't name all of them) are not something you want in the system.
The VE is cooled by fuel and lubed by fuel...that's been noted many times, but it is not meant to have tranny fluid in it for any reason, as far as I'm personally concerned.
Often times we're so worried ( and rightly so) about our pumps that we look for "cost effective" ways to help longevity..but has the impact of deposits in the cylinder, or, on the injector tips, or, the rings been assessed....?? probably not...

The additive market is pretty big...if you really want to use something go with Howes .... it's not big on helping cetane rating but it is good for lubricity....
I know that anything you gotta pay for is more expensive than something you're gonna throw out, like ATF but honestly, I would really kick that option to the curb guy......

pb....

 

Figure I have 4 gallons of it after the change and flush yes 20 qts. Not really worth the risk or the worry for $8.40. I was just kind of curious if anyone did it. I believe I will just keep on going with the B20 or more when I can find it. No sence in getting crazy for less than $10.

 

here's a fun way to get rid of it.... Gasser with a cat conv needed. small resevoir with washer fluid pump. brakeline tubing. momentary switch. braze the brake line tube just in front of the cat converter run the line to the resevoirand connect to the pump ( flex tubing can be used at this end ) mount momentary switch where ya can reach it while driving. fill res with used tranny fluid. Now when some **** decides to tailgate you flip the switch for an instant smoke show. works best with a nice hot cat.
