STA-BIL In-Season Fuel System Treatment & Injector Cleaner, 32 oz
The In-Season quart — a working summer's worth of fuel-system cleaning for the whole driveway.
STA-BIL — ready for the first pull of spring





Storage guards the engine that sleeps; In-Season guards the one that works. This is the bottle for the months when the mower runs weekly and the truck never cools down.
A dose with fill-ups keeps injectors spraying clean and ethanol moisture under control, so the machine ends the season running as well as it began it.
Prices and availability are read from each product’s live retail listing — the red button opens it in a new tab.
The treatment for engines that never sit still.
Cleaning and moisture control tuned for fuel that gets burned, not stored.
Keeps the spray pattern crisp instead of waiting for a stumble to fix.
Modern pump gas pulls water all summer; this bottle keeps it from mattering.
Eight ounces rides along and doses a small tank through the season.
