ATF is mostly low viscosity lubricating oil. While it can be a good, mild parts
cleaner, it is not as strong a solvent as diesel
fuel. It doesn't smell as much as diesel, which is a reason to use it to scrub machinery parts
. It will burn with a lot of energy, so your engine
won't run bad if you put a low percentage in your fuel tank
. Clean your injectors? Only if you buy it from ME! Just kidding, it has no volatile solvents that will clean your injectors. Buy injector cleaner.
If the oil sump if overfilled to,the point the crankshaft touches the oil, the resulting foam can be sucked from the crankcase into,the breather, and some may burn. The engine
can also runaway, run at high speed and cause lots of problems. Run fast, blow oil out the exhaust
, and NOT shut down even if you shut off the diesel! I've seen it, and it can be pretty exciting. Just check the oil level. If it is higher than the full line, drain some before starting the engine. Severe damage can result from overfilling
In theory, you could get enough oil in the cylinder to lock up the engine.
