With today’s high gas prices, our gasoline additives will help reduce gas consumption while keeping your engine clean and in optimal performance condition. Our 4-Power® G and 4-Power® D cleans your engine’s entire fuel system from the tank to the injectors. The manufacturer recommends using Fuel Mate Plus® and Diesel Plus® every time you fill your tank to keep the system in top-notch condition. Diesel Plus® also greatly reduces cold start issues during winter months.

Our engine oils, oil additives, and transmission fluids are engineered to withstand tremendous heat and pressure to maintain viscosity and improved lubricity. It reduces friction tremendously which adds thousands of miles to our vehicles and equipment.
