The leaves are falling, football has started, and the kids are back in school, this means for most of us that winter is just around the corner. Don’t wait until the last minute to winterize your vessel as it could cost you in the long run. Here are some tips for winterizing your marine fuel so that you can have peace of mind this winter.
Ethanol can be very corrosive which can cause it to separate from the gasoline and degrade rapidly; it is important to treat it with a multifunctional treatment like ValvTect Ethanol Gasoline Treatment especially in the winter months. You want to make sure the gasoline tank is 7/8 full to avoid condensation developing that can cause phase separation of the ethanol.
Important details to address:
- Make sure fogging oil is run through the carburetor and cylinders.
- Use a De-Carbonizer for high horsepower outboards to get rid of hard carbon deposits on the piston head
- Run the engine dry of fuel and disconnect the fuel line while the engine is running.
- Be sure to change all filters.
Diesel fuel is now ultra low sulfur which has less than 15ppm sulfur. Service stations usually contain 5%-10% biodiesel and marinas may have pure ultra low sulfur that is free of biodiesel. Both fuels are eco-friendly but can cause issues with marine engines; it is recommended to stay away from diesel fuel that has more than a very small percentage of biodiesel.
Biodiesel fuel can be prone to bacteria growth which can be treated with an additive called ValvTect BioGuard Plus 6 which also helps to avoid corrosion. Also be sure to lubricate injectors and fuel pumps, stabilize the fuel, change all filters, and fill the fuel tank 7/8 full similar to the gasoline engines.
Following these steps will ensure that come spring you won’t have any complications and will be on the water in no time!
