Lucas Low Viscosity Stabilizer is a premium, synthetic engine oil treatment that improves performance in four key areas: Anti-Wear, for the life of your engine. Friction Reduction, for fuel economy and power. Dispersancy, to reduce sludge, varnish and carbon to keep your engine clean and oxidation Inhibition, to prolong the useful life of your oil. These are key performance characteristics that improve any oil; petroleum based or synthetic. They are especially important in today’s engines that are smaller, yet more powerful than the engines of yesterday, stressing vital engine components and the oil that protects them.
