What is the purpose of an oil ring assembly?

The oil ring assembly's primary job is to scrape excess oil from the cylinder walls as the piston moves down. This prevents oil from entering the combustion chamber, which helps reduce oil consumption and exhaust smoke.

What does 'standard tension' mean for an oil ring?

Standard tension refers to the spring tension of the oil ring. It's designed to provide a good balance between effectively scraping oil and not putting excessive pressure on the cylinder walls, which is important for engine longevity and performance.

Can these rings be used in California?

No, these rings are not CARB approved and cannot be shipped to California due to emissions regulations.
