Forté Seal Conditioner is a synthetic seal treatment which restores the elastomer properties to seals.

A major cause of oil burning and exhaust smoking in automotive engines is due to the valve stem seals hardening and shrinking, which results in oil leaking past these seals into the combustion chambers. This condition can be treated by adding Forté Seal Conditioner to the crankcase oil.

Forté Seal Conditioner is compatible with all conventional crankcase and gear oils, including fully synthetic and semi-synthetic engine and gear oils. Forté Seal Conditioner is not compatible with aqueous and non-petroleum oil-based fluids.
