No Smoke Engine Oil Treatment w/ Stop Leak


Packaging: 350mL


Stops Leaks
Stops Exhaust Smoke
Quiets Noise
Improves Combustion

Excessive exhaust smoke is caused by worn piston rings or leaking seals causing oil to burn in the combustion chamber.  The burned oil is then released through the exhaust and commonly seen as blue smoke.  These problems do not just occur overnight.  It’s a progressive effect of normal wear on your vehicle.  In many circumstances, the cause of smoke will be both the gaskets and rings.

Bar’s No Smoke Engine Oil Treatment with Stop Leak is a powerful, dual-action formulation containing a special blend of chemicals that will both improve the performance of your engine oil and protect the engine by stopping leaks, noise, and smoking.  All this while preventing future and present leaks by conditioning the aged seals.
