Will old gasoline harm a snow blower? No more than it will harm any other gasoline engine. Gasoline has a number of different vaporizations fluids. Some higher than others. If the gasoline is very old, all the higher vaporization point fluids may have evaporated. Then you may have trouble starting. Another question for you to consider is: How old is old? If the gasoline is only a month old or even several months old probably no problem. But, if it is six months or over????? How much do you have? Even at $3.00/ gallon why take a chance. If you really want to use it, start the blower and after it is running well, add some that has been mixed with new gasoline. That way you can use it and not have any troubles.
The best gas mileage from unleaded gasoline or premium gasoline depends on the car. Old cars get better mileage from unleaded.
Nothing. 4 month old gasoline is still good enough to use. Gasoline starts to go bad after 1 month but can be used up to 6 months after it was refined.
8 and up
newer gasoline from the past 3-4 months in most places has 10% ethanol in it they sell an additive if you have anything with a small gasoline motor (lawnmower, 4-wheeler,etc) so it doesnt mess up your engine or fuel system when you mix the old gas and new gas
Fresh gasoline may help soften or break down varnish formed by old gasoline, but it may not completely dissolve it. It's best to use a dedicated fuel system cleaner or consult a professional for more effective removal of varnish buildup.
Yes, gasoline starts to go bad when it is about 1 month old. After 6 months you should not burn it in an engine unless you have put a fuel stabilizer in it. In that case it will be usable for about 8 months. This is also important with small gasoline engines on lawnmowers for example. Bad or old gasoline can damage a small engine very easily.

Old gasoline can be disposed of at a hazardous waste facility or a designated collection site. It is not safe to pour it down the drain, on the ground, or into the regular trash as it can be harmful to the environment. It's important to handle and dispose of old gasoline properly to prevent any negative impacts on human health and the environment.
Depends how old. A few months, no problem. A few years, there can be a problem.
It is possible.
