Premium gas, such as 93 octane, helps high-powered cars run smoothly and efficiently. There's no need to run a small lawnmower engine on high-octane gas, but it won't hurt your lawnmower, either. The only harm might be the dent left in your wallet from using the more expensive fuel..
Regarding this, what fuel should I use in my lawn mower?
Most four-stroke engines require fresh unleaded gasoline with an octane rating of 87 or higher. You can use gas with ethanol, but more than 10 percent ethanol is typically not recommended. Mowers with two-stroke engines use that same type of gas, but with the addition of a high-quality two-cycle engine oil.
Additionally, is octane booster bad for your engine? A lower octane fuel than what is recommended can damage the engine as it causes 'knocks' or irregular ignition. High octane fuel and boosters have negligible or absolutely no effect on low performance road-going cars. A manufacturer recommends a minimum octane fuel rating and these products will not make a difference.
can you put car gas in a lawn mower?
No, the lawnmower wasn't a 2-cycle. I bought a battery electric mower to replace the gas mower. Even if the gas is two cycle, gone stale or both, just make sure you dump it in an almost full auto tank.
When should I use my gas stabilizer on my lawn mower?
Use fuel stabilizer in your mower's gas tank when storing it for 30 days or more. Or, if you have a small lawn that only requires infrequent mowing, you can extend the life of gasoline stored in a container by adding fuel stabilizer to it.

E10 fuels are approved for usage in lawn mowers and outdoor power handhelds like chainsaws, trimmers, and leaf blowers. Gas with higher concentrations of ethanol is not.

While E10 fuels are approved for use in lawnmowers and other outdoor power equipment, gasoline blends that contain higher levels of ethanol are not. In fact, the use of a fuel with more than 10 percent ethanol can actually void your equipment's warranty.Can I mix old gas with new?
On its own, old gas has lost some of the potency that would have enabled it to fire an engine, but it's often safe to use up by diluting with newer gas in the tank of an outdoor power tool or vehicle. For larger quantities of gas, you can dilute it in your car or truck's gas tank.What octane is best for lawn mowers?

Octane boosters claim to increase the performance of a vehicle. The only time these additives work is when you are not using the right octane rating fuel as your vehicle requires, and you increase it with what is supposed to be an additive.

Wusz said, “An engine does not know what the octane rating of the fuel is, unless it is too low”; note that we made less power by adding booster to 91-octane fuel. Race fuel tends to have a more powerful formulation than pump gas, regardless of octane rating, because it is denser and can release more power and heat.
