Do you need to drain the gas before winter storage? Not if you treat it. STA-BIL Storage keeps fuel fresh for up to 24 months and stops the gum and varnish that clog a motorcycle’s carb or injectors while it sits.
How to use it on a bike
Add it to fresh gas. 1 oz treats 2.5 gallons, so this 16 oz bottle treats 40 gallons. That’s a lot of winters for a 5-gallon tank.
Fill the tank to about 95%. Less air space means less condensation.
Run the engine for 5 minutes so treated fuel reaches the whole fuel system.
It works in all gasoline, including ethanol blends up to E-85 and non-ethanol, and in 2-cycle and 4-cycle engines. It has no alcohol in it. STA-BIL says it also removes water to prevent corrosion and cleans carburetors and fuel injectors. Made in the USA.
Use it any time a bike will sit 30 days or more, not just over winter. Fuel is one part of the job; our motorcycle storage guide covers the battery, tires and cover. It’s also in our Winter Storage Kit with a UV protectant and moisture absorber.
