Do you throw ATF in your Diesel Fuel?

My ex-father-in-law used to do this with his old 6.9 & 7.3 IDI engines. Told me it would clean the injectors. He did it like every other tank. I'm not doing it on mine. Don't know if it'd help or hurt. /ubbthreads/images/graemlins/shrug.gif

I have thrown a quart of regulat ATF in my diesel fuel when I go on long trips. It seems to help my fuel mileage. What is the common opionon on this?

it does add lubricity. But it also adds ash that don't burn properly which can assist in loading your rings over time. It also is dyed with the same red that the IRS uses to mark untaxed fuel and I have heard of people getting screwed over by the taxman after having their tanks dipped and traces of red dye from the ATf has been found.
A better choice, believe it or not, would be clear generic power steering fluid. It's basically the same as ATF oil wise, except it's clear in color and contains significantly less EP & AW additives which significantly lowers ash content.
An even better choice would be to add a quart of B100 biodiesel instead.

Hi nmhs,
I have 24k miles on type F used at 1qt/100gal. Makes the injectors quiten right down. It does nothing for fuel mileage according my test road. You have to add 100 times the above quanity to get a slight color change in #2 and #2 has a ash content according to API.
With my old 4cyl IDI I have about 350k miles using ATF type F and never replaced any injectors. A very cheap effective injector lube.

It is 100% straight Biodiesel. Biodiesel is another form of fuel made from vegetable oil. Don't confuse this with those that run straight vegie oil as those require engine mods. Running BD requires no engine mods and those that have tried it like it. You can run from 5% to 100% as it can be mixed with dino diesel. For more info there is a section on Biodiesel on this forum. I don't have a source around here but I am considering making a batch of a couple hundred gallons and giving it a shot!!
I have this stuff called Moly Black Gold transmission additive, its pink in color of course, but has QX in it, I use half a bottle and add 2 ounces of Acetone to it, and add that to the full tank of fuel. I havent tried it on the diesel yet, but it did make a difference in my Crown Vic, I saw a 1.5 - 3 MPG increase over three tanks of gas, and the engine ran a bit smoother. I havent tried it in the truck yet, mainly because of the red dye.

I have used a product called "SeaFoam." It says it is for gas or diesel. Found it at NAPA.
I spoke with a Ford Technician this afternoon, he stated that it is probably not good because of the detergents found in the ATF. But then he was standing around some other ford employees. I once had a retired dodge mechanic and other mechanics tell me it is good for the engine. Hmmmmmmm???? Just to stay on the safe side I might quit using this.
I have used Bio Diesel in my tank and it is great. Better MPG (1-4), quiets the engine, all my temps (except tranny) were cooler, no loss of power. My engine loves it. Run a batch of B100 and change your fuel filter. The biodiesel cleans so well it can actually clog your filter. It cleans everything it touches. Your pump, injectors, tank, etc. will love you for it.

I learned along time ago that you have to be real careful about what additives you use. Cost me an engine overhaul. Ever since I use only the oil and fuel that is recommended with no problems. I don't believe in additives at all.

[/ QUOTE ] Not sure if it is the same product but on our job (FF) we use it in our two stroke and four stroke rescue equipment. It has been known to gunk things up but that is on equipment with pin hole type injectors

I have a Buddy that buy's a new GMC diesel pickup every year. Same dealer, model, reg cab, 4x4, long box, white. Same old beat up treated 4x8 plywood in the bed. He most likely puts on 8,000 miles max. I am sure the trucks never see 70mph. One oil change before he trades it in. He's been doing this for maybe 20 years.
He pours half a quart of ATF in his tank every other fill up. He claims it keeps the injectors clean.
Personally, I think this is a really really old OTR truck drivers trick that is not required with the new engines, todays diesel fuel, and with the commercial additives that are out there today. I never use additives unless my motor seems to lose power after a fill up of bad fuel. Then I'll put in a quart of whatever Cetane/injector aditive I can find. All the brands seem the same to me.
But, my Buddy swears by the ATF.

It is an old OTR trick to keep the engine running smooth, not needed in todays electronically controlled injection systems though. It was mainly for the injection pump itself, not the injectors.
