Tim has a 120K Miles on his Honda and after adding Lucas Oil Upper Cylinder Lubricant the engine runs smoother and quiter with less vibration

I have a 2000 Honda civic with 120k miles, I've done regular maintenance on the engine and it still runs good for a 12 year old car.  Lately I've noticed some more vibration at idle and slower acceleration, so I added a bottle of Lucas Oil Upper Cylinder Lubricant and Injecter Cleaner.  WOW, what a difference!  The engine runs smoother, quieter, and with less vibration.  Along with the Lucas Oil Stabilizer my engine has never run better.  Your products are the best on the market by far and cost no more than other brands. 

Keep up the great work!
