Excessive oil burning and exhaust smoking can appear in older worn engines. Oil burning and 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. Instructions: Add one bottle STP Smoke Treatment at or between oil changes. Mixes with regular and synthetic motor oils.
