Transmission Oil Mixed With Diesel Fuel?

So Ive Heard of people putting a bottle of trans oil into there diesel fuel tank. I think its not a good combonation! Let me know whatcha guys think

works fine for farm diesel but don't add any red color for road fuel. I add oil change oil to my diesel tanks all the time. been doing it since the mid 80's. i really don't recommend it for winter time unless the unit runs all the time. my loader tractor likes to jell up with it.

yea, I thought the whole thing was rediculouse. an over lubricated engine isnt the best thing, Unless you want to hydrolock it

And besides when you mix Trans oil to your diesel fuel, You'll have a marginal loss of power

Makes sense, I guess, you change the engine oil 'cause it's dirty and abrasive and you don't want it wearing out the engine bearings, so you then drain it and add it to the diesel fuel, which passes through the IP and injectors, with clearances a factor of hundred or a thousand CLOSER than the engine bearings, and CO$TLY to boot.

Yep, makes perfect sense, I guess!

been meaning to talk to you about your people skills....................

As a kid working in a gas station decades back, was a fella that pulled into the station every Sunday with his new car hauler after making a delivery to the Ford dealer across the street that dumped a quart into both of his 100 gallon tanks. Did it every Sunday for the two years that I worked there, swore by its ability to clean and lubricate his injectors. I've never done it with my diesels, but again, every Sunday for the two years that I worked there, like clock work, without one single failure. I use Howes and PS, but will not knock what I saw the guy do and swore by, again, without a single failure.

huhh, what you talkin bout!

Why add anything? Transmission oils contain seal swellers and a lot of other additives. Why would you want to add it to your combustion chamber.

I have a friend who was an Allis Chalmers dealer for over forty years and he swears by putting a quart of ATF in a tank of fuel.
ATF has an affinity for water and it will remove water from fuel. It also has lubricating characteristics and will lube the pump.
I believe that adding a quart of oil or ATF does not diminish the fuel's ability to produce power,it increases it.Adding oil is adding potential energy,if you ever threw used motor oil on a brush fire you will know the explosive potential energy it can generate,thus in the combustion chamber it is more potent. I would like to hear reasons why some don't believe this. The trucking industry uses large filtering systems to filter used motor oil which they add to their diesel fuel tanks,up to 10% oil in their diesel,a very economical way to get energy from waste.
I use ATF in my two diesel tractors,I also use a product called 3in1 Diesel Conditioner.This product contains a cleaning agent that cleans injectors and other components of the fuel system,kills bacteria,removes water and lubes the pump.I don't put ATF in every tankfull,maybe every third or fourth,the conditioner maybe every fifth or sixth tank..or when I think to.I don't have trouble with bacteria and water in my fuel and I've never had to rebuild a pump. Thats my story,others may vary!

How about adding 2 cycle oil to the fuel?

I sold oil and grease for 14 years. Anybody that has ever sold oil and grease professionally will tell you that ATF contains abrasive additives to help the clutches in the auto trannys grab and not slip. Why would you want to put an abrasive substance into your diesel fuel? Buy a PREMIUM diesel fuel from a reputable FARM supplier and forget about adding anything to it.

It won't hurt anything and might occasionally help something like a sticky IP. I've got a Mercedes diesel car with a slightly sticky IP (doesn't idle down like it should) that reacts well to a quart of motor oil in the tank. I've been running a little Power Service Diesel Kleen in that one and a quart of motor oil every couple weeks and its getting better. Probably ought to have the IP serviced but that'd cost more than the car is worth...

Other than that I'm not a fan of snake oil for the "cheap insurance" idea.

????-Heavier oil has more btu's per gal, right

Just so I know, what fluid did you sell? I want to make sure I never buy it. ATF should NOT have an abrasive additive.

It gets enough of that from the wear particles off the clutches and bands.

How about Marvel Mystery Oil?

I know a guy running mostly recycled engine oil in diesel heavy pickup, gets the oil from oil changes in his shop. Oil goes through 3 filters before it gets to the fuel tank, so relatively clean. Ryder Rental trucks get the old oil into fuel tank treatment except in winter, similar filtering from drain pan to holding tank with filters then into fuel tank. For farm tractor use? Roosa Master pumps need a litle lube in fuel- that's why Roosa Master lube additive in cans is sold for twice the price of plain oil- and the early GM car pumps really needed the extra oil lube. Current ultra low sulfur road diesel is clean burn but may not be best for some older pumps- the use of BioDiesel is a 'iffy' situation also, some extra slippery, some extra dry depending on what goes into the 'Bio': Tallow, fresh soybean, recycled peanut, Canola oils vary. For some winter use users the fuel is 25% unleaded gasoline mix- the addition of good 2 stroke oil in a rough 50 to 1 for gasoline is a recommendation for the snowcats. Here in wisconsin winters a truck coming from the south with heavy diesel in tank is advised to add 10% unleaded and a can of straight 10 weight for every 10/20 gallons of gas put in tank- beats paying for overnight heated garage to thaw out lines or tow to service garage for pump out, thaw out. Tranny fluid with friction additive pack? Maybe the early Type F for Ford had some 'grabby' additive pack but the Dextron mix's are slippery, relatively high detergent to help clean. RN

I've been running type F at the rate of 1qt/100gal for the past 30yrs and have about 400,000miles on a couple smokers. I've talked with several OTR drivers that's been using the same since the 1940's. I have 35ooo miles on my 02 F350 7.3 PSD without any problems.

There was a guy (passed away a few years back) that was maintaining a fleet of hot shot rigs in Houston. That was TexasTownCar. He kept accurate records and ran half of the diesels with type F and the other half without any type of additive. The paper work said he getting better than twice the life span from the injectors that was running the type F mixture. TTC died before the tests were concluded but they were over a million miles at that time of his death. These were all 7.3 PSD engines that were being tested.

And [b:cabd2a4cbb]NO[/b:cabd2a4cbb] at the rate of 100 times the rate of type F being added and that did [b:cabd2a4cbb]NOT[/b:cabd2a4cbb] change the color of #2 to anything close to a red color. That was just not a concern.

Both CAT and Cummins have a automatic oil change systems that uses used engine oil on the fly for 100000 mile oil changes for OTR engines. Neither have reported any related problems with such systems.

i have a friend who is a mechanic at a ford dealer.
he has his co-workers save all the used atf that is not burned looking. he has a 97' power stroke. he keeps straight #2 diesel in the front tank & puts straight used atf in the rear tank, he always starts the truck with diesel & switches to atf after it warms up. he runs 50/50 diesel/atf in the rear tank in the winter. he's been doing this for 3 years now without any problems. he's recommending that i do the same ( i also have a 97' powerstroke ) but i'm kinda' sorta' skeptical.

As well you should be. My 87 year old FIL figured he would save some money by putting around 5 gals water in his powerstroke. The truck ran pretty good for about 5 yards, then it shut down. After spending $200.00 for a fuel system cleaning, it is running pretty good once again. - At least he didn't pour gasolene in it.
