Will fuel in oil burn off?

$5-10 extra for a premium tankful makes this a rather expensive way to dispose of old oil. To say nothing of engine parts such as the cat and O2 sensors. And fuel filters, cringe.

If this was literally my only way to do that, I would a) let it sit for a month to settle out metallics and soot, and b) filter it to 5 microns.

Then add it at less than a quart per tankful, reducing further as needed so the engine doesn't smoke. Smoke means incompelete combustion means you are torturing the catalytic converter to death (never mind the metallic junk in the oil if you don't filter it, which will poison the cat). And running the fuel injection systeem out-of-gamut: meaning the fuel injection system is designed to adjust for variations in fuel and still run clean and stochiometric, but this fuel is too different from normal fuel and is beyond the system's ability to adjust for it. Reduce the ratio.

Really, a better plan is to do the settling and filtration I mentioned, then blend it into an old diesel engine at 50:1 or so. I am unclear how you can be so far from civilization that it's a chore to take used motor oil to an auto parts, and yet, there are no farmers around?

I would not use it for 2-cycle oil as that is too critical an application.

Or even better, after settling, use it as makeup motor oil to replace oil burnt between oil changes. Then you don't need to do the filtration because filtration needs for oil are different than for fuel... Also the car has an oil filter. I hope you've change it from time to time.

My local mechanic changed my oil and added too much. When i started driving home, after about 3 mins, it started pouring out thick white smoke. I immediately pulled off the next exit ramp from the freeway (drove about 6 miles). I had a tow truck take my car to the dealership. They did a major tune up and replaced the spark plugs, cleaned the fuel injector, flushed my transmission fluid and obviously drained and replaced my oil and filter. The service manager said it was fine and that the smoke was decreased about 95% (which it has). He also said it would take a few days for the excess oil to burn off so that my car would stop blowing smoke from the exhaust completely. The smoke that still comes out is not very much, but is still noticeable. It has been 2 1/2 days since they repaired it.

My question is: How long average wise will it take for my engine to completely burn off the excess oil and stop this little bit of annoying smoke?

ps: My car is a 2000 Toyota Solara w/100k miles.
