It is recommended that you add the Oil Stabilizer with every oil change (20% Stabilizer, 80% Oil). You may also use the stabilizer to top off between oil changes in order to help reduce oil consumption in an older engine, or maintain peak performance in a new engine. In addition to being great for your engine, you can also mix it 25%/75% in the transmission and 50%/50% in the differential. Lucas Oil Stabilizer blends with any petroleum-based or synthetic oil, and is formulated for gasoline or diesel engines.
