Environmental issues have resulted in lower-performance diesel fuels in on-road and off-road uses. Engines are subjected to more wear and lower fuel economies. Assurance of a clean engine and complete fuel combustion will result in maximum fuel economy, longer equipment life, reduced emissions and lower cost per mile or hour of operation. LE's BTU+ is designed to provide this protection for year round use. Total Treat will clean fuel pumps, injectors and combustion chambers; lowers pour point and cold filter point; improves fuel lubricity; retards microbial growth; lubricates injectors and pumps.
