Kortez Brown uses Upper Cylinder Lubricant and Injector Cleaner in 2004 Chevy Trailblazer.

I just wanted to let you know how much of a difference your Upper Cylinder Lubricant and Injector Cleaner has made in my 2004 Chevy Trailblazer. I was down to about a 1/4 tank of gas when my SUV started to run rough. Almost like one of the cylinders was not firing correctly. I ran the tank down to almost empty and ran to the Checker's Auto Store to grab a bottle of fuel injector cleaner. I've used fuel injector cleaners before, but I decided to ask one of the sales reps which one he recommended. He pointed out the Lucas Injector Cleaner. I drove to the gas station down the street, poured the cleaner into the gas tank, and filled my tank full of 91 octane gas. I noticed an instant difference in acceleration and response time when passing cars on the highway when I decided to pass someone. I am extremely pleased with this product and I will recommend it to my friends and family. I will also explore the uses of other your products in my Trailblazer.

thanks, Kortez Brown
