STP Smoke Treatment (14.5 fluid ounces)

Reduces exhaust smoking. E-Z flow bottle. Oil burning and exhaust smoking occurs 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 parts and created gaps between the cylinder walls, piston rings and valve guide seals. STP Smoke Treatment provides a thicker oil cushion to help: reduce oil consumption and smoking; decrease metal-to-metal contact; cushion noisy valves and lifters. Questions or comments?
