CRC’s first brand of diesel additives was SILOO® Heavy Duty, added with the SILOO acquisition in 1983. The Aviex® brand followed through the acquisition of K&W in 1991. The merger of these two strong brands under the CRC umbrella became today’s CRC DIESEL line.
CRC DIESEL heavy duty products are comprised of the best formulas from the original SILOO and AVIEX brands as well as some new formulas unique to CRC DIESEL.
