I have a couple of gallons of left over gas/oil mix (50:1) (with fuel stabilizer added) from my 2 cycle outboard. It is getting to be about 2 years old and I am afraid to keep it for another year. Any suggestions on how best to get rid of it? A friend suggested adding it to my car a gallon per tank full. Would this hurt my cars engine or will it be so diluted that it won't matter? I don't want to dump it and I don't want to use it next year.
