If your R134a automotive A/C system has lost oil due to leaks, component replacement, or system service, OilCharge3 restores the lubrication your compressor needs to operate properly.
Oil loss is one of the leading causes of premature compressor failure. OilCharge3 delivers a precisely formulated blend of selected oils designed to replenish lost oil and protect internal A/C components.
This aerosol oil charge installs just like refrigerant — through the low-pressure service port — making it simple and effective for technicians and DIY users.
