STA-BIL In-Season Protection

STA-BIL Storage is for when the bike sits. In-Season Protection is for when you’re riding it. Add it at every fill-up and it cleans the fuel system and fights the corrosion that moisture and ethanol-blended gas cause.

That matters on a motorcycle that gets ridden on weekends and sits in between. Ethanol gas pulls in moisture while it waits in the tank. In-Season Protection is made to handle ethanol blends, non-ethanol fuel and condensation, and it keeps fuel fresh for up to 12 months.

Which size?

• 4 oz small engine: for machines with a gallon or two of gas in them: scooters, small dirt bikes, generators and 2-cycle equipment.
• 10 oz: the size to keep on the garage shelf next to a full-size motorcycle. A good fit for one rider treating fill-ups through the season.
• 32 oz: for treating every tank in the household: the bikes, the truck, the trike and the small engines, or a long riding season.

• Add it at every fill-up. Use the dose printed on the bottle.
• For all gasoline engines, including 2-cycle: motorcycles, cars, outdoor power equipment and other small-engine vehicles.
• Made in the USA.

Tip: treat the gas can rather than each machine. Every tank you fill from that can is covered.

One thing it isn’t: a long-term storage stabilizer. When the bike goes away for winter, switch to STA-BIL Storage, which keeps gas fresh for up to 24 months. Our motorcycle storage guide covers the rest of that prep.
