Purpose and Specifications
LIQUI MOLY 25008 Marine Fuel Stabiliser keeps your boat's gasoline fresh and reliable, protecting it from aging and oxidation that can gum up your engine during storage or infrequent use. This 500 ml bottle treats up to 100 liters of fuel, with the built-in dosage chamber making it easy - just one fill (25 ml) handles 5 liters perfectly.
Designed for all 2-stroke and 4-stroke marine gasoline engines, it prevents corrosion across the entire fuel system, stops storage damage, and stabilizes fuel even with organic ethanol content. Flash point at +40°C means it stays safe in typical marine conditions. Long-lasting protection ensures your engine starts right up after months of sitting - ideal for seasonal boaters.
When to Use / Replace?
Add before storing your boat for the off-season, or use regularly in engines run less than once a month. One treatment protects fuel for up to 12 months of storage. Mix at a 1:200 ratio, add to the tank, and idle the engine for 10 minutes to distribute. Refresh every 3-6 months for long-term seldom-used motors, or when fuel smells off/varnishes form.
- Perfect for winter layup or summer dockside storage
- No need to drain fuel - saves time and hassle
- Works in temps down to freezing, keeps fuel flowing smoothly
