And when gas at the pump varies in quality, the result is deposit buildup, inefficient ignition and combustion, and poor power output. To make matters worse, small, high output engines are extremely sensitive to deposits that build up on fuel injectors, intake ports, on intake valves and in combustion chambers. Even small amounts of deposits cause increased exhaust emissions, reduced fuel economy, drivability problems, and engine knock.BG Platinum® 44K® is 11 ounces of high-quality detergents that you pour right into the gas tank to restore performance and gas mileage.
