This gasoline storage stabilizer listing contains 4 containers of 1 gallon each. Calculated treatment capacity is up to 320 US gallons per container, or 1,280 US gallons across the case, at the published Storage rate. Seasonal equipment often remains unused with fuel still in the system. A gasoline storage fuel stabilizer is intended for that storage-planning task, helping limit fuel deterioration and gum or varnish formation when used as directed. Add it to fresh fuel rather than relying on it to restore fuel that is already badly degraded.

Case quantity is a purchasing choice, not an application instruction. Keep unopened units stored as their individual labels direct and plan consumption without assuming a guaranteed number of engines, jobs or seasons. Use the correct dose or approved aerosol method each time.

Choose a package by the amount of gasoline you intend to treat over time. The treatment rate is different from the Marine formula and from diesel treatment, so measure using this product’s own directions. A larger container provides more additive; it does not change the dose or extend the stated protection period.

Before lay-up, check the fuel type approved for the equipment and follow the engine manufacturer’s storage procedure. Fuel-system treatment and internal engine preservation are separate maintenance tasks. A stabilizer is not a reason to skip other required storage steps or to use an otherwise unapproved fuel blend.

Keep a record of the treatment date, amount of fuel and measured additive. Reclose the container according to its label after use. Compare package sizes using current prices and your planned fuel quantity rather than assuming the entire container belongs in one tank.

FUEL & ENGINE CARE GUIDE

Plan the Correct Gasoline Storage Fuel Stabilizer Task

Check the equipment, product identity and directions before starting. Use these six checkpoints to match the maintenance task to the correct formula and application method.

Compare the Formula, Package and Maintenance Task

Compare this case of 4 with the separately listed single container before choosing purchase quantity. The case provides multiple containers for planned work; it does not change the formula or the application instructions for each unit. Check current prices and order the package that fits your maintenance schedule. At the documented Storage rate, the calculated case capacity is 1,280 US gallons of fresh gasoline across individual treatment events. Compare STA-BIL Fuel Stabilizer - 1 Gallon

For a gasoline-powered boat used frequently, review the separate marine fuel treatment and its own directions. Storage treatment and every-fill marine care have different positioning and dosing. Select by fuel type, use pattern and the equipment manufacturer’s requirements. Compare STA-BIL 360® Marine™ - 1 Gallon *Case of 4*
