It keeps the internal parts lubricated
If your lawnmower is a 2 stroke mixing oil in the gas is what it needs to run right. If your lawnmower is a 4 stroke mixing oil in the gas fouls the plug and makes it not run.
50 parts gas to 1 part oil. So the amount of oil would be 1/50th the amount of gas.
it is the ratio of gas to oil 32 parts gas 1 part oil. it is easier to mix it if you have a mixing container.
gas and oil should not be mixing in any vehicle approved for road-use.
Typically this is caused by a dirty carburetor causing gas to leak through and into the crankcase.
This is going to depend on the manufacturer's recommendations and also the type of 2-stroke oil being used. What are you mixing the gas for? What type of oil do you have?
An Oil Injected motor will have a separate Oil Resevoir, so mixing Oil and Gas is not required, and in fact inadvisable.
If you mix the oil and gas together in the proper mix and do not add oil to the oil resivoir you will be fine.
if it won't crank and gas is mixing into the oil you probably have a messed up pistonor gap in the cylinder wall
no
If its an oil injected motor there is a tank that holds the mixing oil if its just a straight carburated motor the oil mixes with the gas in a can then put it in the gas tank.
it either wont run or the explosion will be so poor it will barely will
