Case of 12 containers
8 oz per container
Listed case code 22239CASE
This marine gasoline fuel treatment case contains 12 containers of 8 oz each. Calculated treatment capacity is up to 80 US gallons per container, or 960 US gallons across the case. Dose each fuel quantity separately. Marine gasoline fuel treatment is intended for the fuel-care needs of gasoline-powered boats and other suitable watersport equipment. The manufacturer positions this formula for use at every fill-up, supporting fuel-system cleaning and corrosion protection when used as directed. It is a different product from diesel stabilizer, fogging oil and a carburetor-cleaning aerosol.
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 the container quantity by how much fuel you plan to treat across your refueling schedule. The measured rate remains the same across the listed sizes. Calculate the dose for the fuel being added or treated rather than using package size as a single-tank instruction.
Before selecting a marine ethanol fuel treatment, check the gasoline and ethanol limits approved by the engine manufacturer. The additive’s compatibility statement does not authorize a fuel blend that your boat or engine does not permit. Review the product label and refueling procedure before application.
If the boat will be laid up, compare the storage instructions for this formula with the requirements of the engine and fuel system. Fuel treatment is one part of maintenance and does not replace inspection, water-separator servicing or other tasks required by the equipment manual. Keep the remaining additive closed and stored as its label directs.

What Customers Say
Excellent protection for my outboard – case is great value
I ordered the case of 12 for my fishing boat and it arrived quickly in perfect condition. STA-BIL 360 Marine keeps the ethanol fuel stable all season and through winter storage. Easy to measure and pour, no more water issues or rough running. Highly recommend for any marine engine.
Reliable fuel stabilizer – fast shipping and solid performance
Bought the case of STA-BIL 360 Marine and shipping was fast. I use it at every fill-up on my pontoon. It removes moisture, prevents corrosion, and the engine starts right up even after months of sitting. Great value buying by the case for multiple boats.
Works well, good bulk deal
The product performs as expected – stabilizes fuel and helps with ethanol problems on my outboard. Case of 12 is convenient and arrived on time. Only reason for 4 stars is I wish the measuring spout was a bit more precise, but overall solid value and effective protection.
Best marine fuel treatment I’ve used
Purchased the 12-pack case and service was excellent with quick delivery. STA-BIL 360 Marine cleans the system, keeps fuel fresh up to a year, and my boat runs smoother with better throttle response. Perfect for seasonal storage and regular use. Will keep buying this.
Great bulk buy – protects engines year-round
Ordered the case of STA-BIL 360 Marine 8oz bottles. Shipping was prompt and packaging secure. I treat every tank and notice less gum and varnish buildup. Excellent water removal and corrosion protection for my jet ski and small boat. Worth every penny for the case discount.
