Burning "scrap" oils and fluids

[RalphVa]

I had some leftover Type A auto transmission fluid that I put some both in my tractor and my old Benz diesel. Transmission fluid is in the boiling range next higher than most diesels and is often included (in the refinery) into the diesel pool, as long as they make final boiling point, smoke point, etc. specs. So, putting a little bit of auto transmission fluid (and presumably UDT) into your diesel should be no problem. The Mercedes Star, many years ago, used to have people writing in it recommending a quart of auto transmission fluid in the diesel tank every so often.

Ralph, anybody, does JD303 tractor fluid also meet those ATF specs? And does it accumulate harmful stuff, lead etc, while in use?

Metals it will entrail will be dependent on the bearing materials used.. It at least won't have combustion by-products in it.

If it has brass or bronze in it.. I'd look at the MSDS anyway..

New clean leftover atf is alot different vs waste oil.

I've heard of adding clean atf oil to diesl for a long time now... that wouldn't bother me compaired to dumping cruddy engine drainings intot he tank of my multi-thousand dollar tractor...

I don't know for sure what tractor tranny fluid is. I know the lo vis stuff I buy for my CUT 4010 is pretty thin, much like auto transmission fluid. I'd certainly run it through a filter before mixing with diesel. Wouldn't use more than a quart per tankful either.

Auto transmission fluid is technically a 5 grade that gets refined in lube oil processing to a 0 to 5 grade. It starts life as, what we call in the trade, as 100N distillate. By comparison, a 10w oil starts life as a 150N distillate off the pipe stills. When we didn't need 0 to 5 grade, that 100N distillate got dumped into the diesel pool. The 10w oil plus about 20% additive can be made into a 10w30 to 10w40 oil for sale as engine lube.

Auto transmission fluid is very highly refined and generally has little additives, even from a dino source. If the tractor transmission fluid is essentially the same (and it appears to be on pouring; I've never seen side-by-side specs), it won't have many additives to worry about that could contaminate the diesel.

Any idea what the extreme pressure addatives inthe utf are?

Even if the oil is new I don't recommend it. New ATF oil has a additive package made up of at least:
Dispersants
Antioxidants
Antiwear
Friction modifier
Copper deactivator
Corrosion inhibitor
Seal swell agent
Viscosity Improver
Pour Point Depressant
Foam inhibitor
Red dye in most ATF's

Which one of these do you want in your injection system? Me personally, none of them. Especially in modern diesel engines the tolerances in fuel injectors are measured in fractions of a micron. It takes very little to start to build up a deposit in them that starts to effect performance.

The best use for used oil is wood treatment to keep the bugs out and waterproofing. Works really well on trailer wood and corral fences although it is a little hard on clothes when rubbed against them. Other uses is like LB said, makes good accelerant for starting brush fires.
I will pay the price for diesel rather than take the chance on messing up my tractor engine. Even a clogged filter or injector is too much aggravation for me to take a chance on running used oil in my fuel tank. If someone wants to run that kind of gunk, get themselves an old military multi-fuel engine. Then if you can stuff it in the tank, it will likely run otherwise stick to the stuff the tractor was designed to burn IE. Super clean #2 fuel oil AKA diesel.

I think the older ones weren't so picky. My operation manual says

For maximum filter life, sediment and water should not exceed 0.10 percent.

That's a huge amount of crud, one part per thousand, more than a half ounce of crud in every 5 gallon refueling. I've never seen fuel that bad but whoever designed this fuel system anticipated that its out there somewhere.

Remember.. waste oil has lots of nice things in it.. like heavy metals.. those things can leach out into the environment. You still drink water? Your kids?

Just because you can do something.. doesn't mean you should.
