THE WORLD’S ONLY SELF-CLEANING MOTOR OIL
Cerma Motor Oil
SiC Run Clean Technology forces carbon to attract to itself, clump, and filter out — so your engine gets cleaner the longer you drive, not dirtier. Available in CERMA 15K and CERMAX 30K blends.
CERMA vs CERMAX — Which is Right for You?
Both blends use the same SiC Run Clean Technology. The difference is drain interval and SiC concentration — choose based on how often you want to change your oil.
