STP® Smoke Treatment

Car exhaust smoke. STP Smoke Treatment bottle

Reduces exhaust smoking and decreases metal-to-metal contact by providing a thicker oil cushion

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 is specifically designed to reduce these problems.


  • Reduce oil consumption and smoking
  • Decrease metal-to-metal contact
  • Cushion noisy valves and lifters
