For everyday life, fuel stabilizers aren't necessary. When a vehicle is driven or used, the gasoline burns up before it begins to evaporate and degrade. For people who own seasonal equipment, classic cars, or boats that tend to sit for more than three weeks at a time, however, fuel stabilizer is a fantastic idea.

Well, does ethanol-free gas make a difference?
While not as popular as the ethanol blends, pure gas may be preferable for older car engines, as well as boats, lawn mowers or other tools. Ethanol-free gas also gets better fuel economy. However, most drivers use the E10 or E15 blends, with 10-15% ethanol. That ethanol content only reduces gas mileage by around 5%.
Though, does fuel stabilizer work with ethanol? Fuel stabilizer keeps gasoline, especially gas with ethanol (E10, E15), from going bad in a vehicle being stored for a half-year or more.
So, when should I use gas stabilizer?
When your engine is in long-term storage, it is important to use a fuel stabilizer. STA-BIL® Storage is formulated to protect the fuel from deteriorating for up to 24 months, meaning that the fuel will remain at full strength and not varnish or gum up the internals of your engine.
Can you put too much fuel stabilizer in gas?
Q: Can you use too much fuel stabilizer? It is possible to use too much fuel stabilizer. Make sure you're reading the instructions for use before adding any stabilizer into your gas tank — you can find the recommended amount and learn how often you can use the stabilizer right on the bottle.

Does ethanol-free gas go bad? Yes, ethanol-free gas can go bad. Ethanol-free gas is suitable for use for around six months if correctly stored and sealed. It lasts longer than gas with ethanol in it can still degrade, especially if it's been exposed to atmospheric conditions.
If stored properly, ethanol-free gas can last up to six months. It is not as likely to succumb to oxidation or evaporation. E10 gas has a three-month shelf life maximum. This makes ethanol-free gas ideal for storage compared to E10.
Depending on the product, the stabilizer can increase gasoline shelf life to between one and three years. Stabilizers work best when you mix them with new gasoline; they're ineffective at slowing the degradation of old gas, and they can't return contaminated gas to working order.
STA-BIL Storage Fuel Stabilizer It eliminates the need to drain the fuel tank before storage and keeps fuel fresh for up to 24 months. ... STA-BIL Storage protects against all the dangers of ethanol and E10 petrol (it in fact protects against ethanol blends up to E85).
Sea Foam Motor Treatment works to stabilize stored fuel up to 2 years. Adding Sea Foam to stored tanks helps fuel resist evaporation, preserves ignition vapors, adds protective lubricity, and prevents the formation of gum and varnish in fuel systems.
If you have an unopened bottle of STA-BIL, it will be good for up to five years. Then once you open the bottle we recommend using within two years for best results. However, after the two years you may still use the product as a fuel system cleaner as long as there is no sediment or flakes.
No problem mixing fuels. The problem exists when you use non-ethanol fuel for extended period of time and then fill up with ethanol fuel. It dissolves the sludge in the tank and causes problems. You will be fine, regular fuel is already a mix of ethanol and gasoline (10% ethanol and 90% gasoline).
Ethanol doesn't produce as much energy when burned vs gasoline without ethanol. Non-ethanol fuel does provide more power and generally better gas mileage in most cases, the exceptions being engines designed specifically for ethanol use. Ethanol does produce a higher octane rating.
The two can be mixed together with no problem. Your atv doesn't care, and won't run any different at all with ethanol or without. Neither one will do any damage to your engine.
Non-oxygenated gasoline is a form of gasoline that has no additives, which increase the oxygen content of the fuel. This fuel has no ethanol or any other oxygenate. Therefore, it reduces the corrosion problems of the engine.
According to Dan McTeague, a noted petroleum analyst, Shell and Esso 91 are both ethanol free. All other grades from the companies have some ethanol content, but the mid-grade blend is pure gas, which means it not only corrodes less than ethanol blends, but is less likely to deteriorate when stored.
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. ... Ethanol will start to absorb water over time, leading to poor engine performance. E10 gas absorbs up to 50 times more water than standard gasoline.
No need to add Stabil if you are using Seafoam. It will stabilize fuel for storage. My bost dealer recommends Seafoam instead of Stabil. Contact your engine manufacturer.
Long story short: yes, gasoline really can go bad. However, there is no hard and fast rule as to when it will expire. ... Generally, properly stored gas can last between 3 to 6 months; if you add fuel stabilizers, you can extend its shelf life by a year or so (under optimal conditions, of course).
