It is difficult to start and emits a smelly white smoke once running.
it floats
You get engine damage from lack of lubrication
If you accidentally put kerosene in your gas tank, you should siphon the tank to remove as much of it as possible. Add about half a tank of gasoline, then run the car as normal. The car may act up some, and if it has too much trouble, take it to a mechanic right away, but otherwise the kerosene should burn up and not cause any real problems.
The engine floods and you have to wait for the lawnmower to drain before you start it up again or it might start smoking.
Drain the oil and catch it in a clean container if you intend on reusing the same oil . Then replace the plug and place the correct amount of oil in the motor.
It depends on where you put the kerosene, but generally, if you just put it in the fuel tank, just drain it, put in new fuel, use some starting fluid to get it running and after fighting the pull cord forever and having it die multiple times and after putting up with the smoke while you clear out the kerosene... it will run pretty much the way it did before. The hardest part will be getting the left-over kerosene out of the engine. Understand that there is some inside the cylinder and it will take a little time to burn it out. Just get as much out as you can then start it. Kerosene is an oil and it will not harm the engine unless you try to use it in the crankcase.
I am out of oil with a delivery scheduled for tomorrow. I went out to the shed to get a 5 gallon can and found a 5 gallon kerosene can filled. I have no smell therefore can not tell if the clear liquid is kerosene or gasoline. I hate to throw it away if it is kerosene, I could burn it in the heater
Nothing happens, except your wallet will be lighter.
to put the oil in the lawnmower's crankcase would be fine, so long as it is an appropriate viscosity.
What is the easiest method of removal of Aromatic compounds in Kerosene Oil?
Then you need to "accidentally" remove it ... pronto, which may mean flushing out the entire coolant system if the engine has been run.
The only time you should place kerosene in a heating system is if it is designed for kerosene.
