Oil burning and exhaust smoking occur when motor oil enters the combustion chamber and is burned along with fuel. This condition, known as oil blow-by, often results when friction and metal-to-metal contact have worn down parts and created gaps between the cylinder walls, piston rings, and valve guide seals. STP® Smoke Treatment is specifically designed to reduce these problems.
