Fuel Mixture 2-stroke oil vs Automatic Transmission Fluid

yeah pepper in the raditor is an old trick but will it last? probably not.
just like putting a raw egg into a hot radiator...the egg will cook and seal up leaks.
sometimes i don't fully understand why some people beleive that "tune up in a can" actually exists. (motor honey, stop leak, and stuff like that) the only true way to fix something is to fix it the correct way or to replace it.
but i can see how on a tight budget, sometimes you just do a quick fix or put a bandaid on something until you have the funds to fix it correctly. but sometimes the band aid or quick fix can cause other problems down the road.
 
1st hand experience with ATF in gasoline engine

I used to work full time in Lawn Maintenance and had a hobby of hot-rodding lawn mower engines. I used to get some motors for free and do minor repairs to them, and then run them all out.

Transmission fluid is a base oil similar to cheap single-weight motor oil, with LOTS of detergents in it. Thats why its red and can slick a whole garage floor with 1/2 quart.

I used to use a spoonful of ATF sucked into the carburetor to clear up sticking lifters or to burn off the carbon deposits in a cylinder.

One spoonful of the stuff did the trick, but now there is SEAFOAM made for this purpose. http://shop.advanceautoparts.com/we...E4&srccode=cii_16776730&cpncode=20-48617371-2

I tried putting a little into the gas tank of a 3.5 briggs that was pretty old but still running fairly strong after cleaning out the carb bowl and jets. (It was in the trash.) It smoked a white smoke for a little bit (expected) then made a loud screeching noise (the rings running dry and sheering on the cylinder wall) and then siezed completely.

2 stroke oil is meant to burn to reduce pollution, and elongate the life of your motor.

If you run common motor oil in your two stroke engine, it will run, and perhaps quite well, but you will see black sludge build up in your muffler, and maybe on your frame or other areas where exhaust floats by (clothing, wheels etc). You will probably have to do more carb cleaning/maintenance, and you may foul more plugs. You may see or smell more smoke from running this.

If you use Synthetic Motor oil (not specialised synthetic 2 stroke oil like ECHO), you will get a lot of white foul smelling smoke and residues coming from the exhaust, and it may suffer in performance.

I used synthetic motor oil in an air cooled 5hp lawn mower engine once because I was out of the regular stuff and cutting a lawn. The mower (a good condition Snapper!) burned up before I finished the small residential lawn.

Just buy ashless 2 cycle oil for dirtbikes or outboard motors and mix as directed.

That's pretty much 100% wrong. Where did you learn that?
 
From a mechanic, and from cleaning up a garage floor. Yes, they put red dye in it also, so people don't put it in their engines.
 
idk if i would do it, funny enough i actualy just acquierd 2 one quart ATF bottles to use as extra or (reserve) tanks because the 66cc engine loves to drink gass, i cleaned them out but you know you cant get every thing, after reading stuff here i am not too worried about it eny more. but yeah, i would not try it unless you have an expendable engine to test it on. (just incase)
 
ATF does have red dye, that part is true. ATF has very little "detergent" (even looking at a simple VOA will show that). ATF is typically the same viscosity as a low XW-20, and most all contain VII's depending on the base oil (most good synthetic ATF's don't use much, if any VII's,) therefore ATF isn't "similar to cheap single-weight motor oil".
 
Ok smarty pants. Would you run it in your 2s engine? I wouldn't. :)

I think it has some kind of solvents then, if you don't like the word detergents. It will eat paint off a car or your bike.

It does have some uses though! I make my own gun oil from it, mixed with Jigaloo in a sprayer.

I tried it for chain lube. It penetrates well but slings too much.
 
NO way would I use ATF rather than a good 2 stroke oil. Makes zero sense.
 
ATF is more of a hydraulic fluid than a lubricant. In a pinch it can also be used in power steering systems but pressures are different in those two systems and can blow seals. Hydraulic fluid has very little lubricating properties as that is not what it was designed for. It's meant to build specific pressure when passed through certain passages causing a desired reaction such as a cylinder being pushed out. I've seen Hydraulic 23 fluid also have a red dye in it, but that was for telling it apart from regular hydraulic fluid that is more of golden color. Besides burning it in a two stroke or four stroke stinks to high heaven.
