Frequently Asked Questions (FAQs)
1. Should I use fuel stabilizer in my lawn mower?
One of the easiest ways to maintain your snow blower or lawn mower engine for seasons to come is by using fuel stabilizer. Whether putting your lawn mower or snow blower away at the end of the season or letting some time pass between uses, curbing your fuel's degradation is crucial.
2. Does fuel stabilizer really work?
Fuel stabilizers keep fuel fresh and effective for at least two years of storage time. Chemical reactions within stored fuel, plus the evaporation of some volatile components, can leave liquid fuels less likely to ignite properly in an engine after more than three months of storage.
