Benefits of Marine Fuel Stabilizers for Storage and Performance
Ethanol-blended fuel may work fine on the road, but it’s tough on boats. A quality marine fuel stabilizer protects against phase separation, corrosion, and buildup that can leave you with clogged lines and rough starts come spring. Pairing your winterization routine with the best marine fuel stabilizer means fresher fuel, cleaner injectors, and a smoother-running engine when it’s time to get back on the water.
Pro Tips:
- Add your marine fuel additive before topping off your tank to ensure proper mixing.
- If your boat will sit for several months, choose a marine fuel treatment designed for long-term storage. It keeps your fuel fresh and your system protected.

Frequently Asked Questions About Marine Fuel Stabilizers
Confused about which marine fuel treatment or boat fuel additive is right for your setup? Here are some quick answers to help you make the right choice for your boat and storage needs.
How does a marine fuel stabilizer protect my boat?
A marine fuel stabilizer keeps gas from breaking down, prevents phase separation in ethanol blends, and adds corrosion inhibitors to protect your tank, lines, and injectors during storage.
