Maxtop uses highly refined high viscosity index mineral base oil or semi-synthetic base oil or fully synthetic base oil, adding excellent performance of anti-wear, anti-oxygen, anti-rust and other additives refined. Keep the interior clean: prevent the formation of sludge and carbon deposits, and keep the compressor clean. Improve operating efficiency: Reduce congestion and failures, improve operating efficiency. Protect internal parts: prevent moisture and corrosive gases from eroding the compressor. Extend part life: Maintain the surface quality of parts and reduce the frequency of replacement. Reduce friction and wear: The right viscosity creates an oil film between the piston and the cylinder, reducing wear.
