The Diesel Fuel we buy is always changing in both chemical content and quality. One constant is the propensity for Diesel Fuel to pick up water. Water in Diesel Fuel remains the number one fuel problem year 'round. Now that ultra low sulfur fuels account for the vast majority of diesel fuel used today, water is now a bigger problem than ever before. Water damages injectors, scores pintles, creates gum and varnish, interferes with fuel combustion and harbors microbes and fungi. Fuel Power contains the most effective combination of ingredients to absorb water from fuel. Fuel Power prevents damage, wear, and premature fuel pump failure. Fuel Power also helps improve combustion and mileage, stabilizes fuel, and prevents sludge. All of these benefits in a unique formulation which contains no harmful alcohols to attack your gaskets and seals. Our concentrated formula treats 240 gallons with only 8 ounces.
