It takes a lot of effort to keep the vehicle running at full throttle. However, you can make this task accessible with a good quality fuel stabilizer. Seafoam has a unique advantage in storing gas-driven equipment or vehicles compared to Stabil. When it comes to cleaning, Seafoam is more expensive, but it does a great job. Stabil and Seafoam contain alcohol and naphtha, two essential ingredients for fuel stabilization. Both remove moisture, the leading cause of corrosion in tanks that have sat for an extended period. Removing moisture helps keep the fuel as pure as possible.
