If I wasn't a believer before, I am now! After running this new truck for 2 weeks, we were disappointed with the 5.7 mpg that we were getting ,so following the directions for extreme cases, I added 1 gal US Lube upper cylinder lube/injector cleaner to 200 gallons..two tanks later I followed the directions for normal and added 1/2 gal to 200...and after burning that fuel, my truck was getting 6.7 mpg...a full mile per gallon increase!!! I AM IMPRESSED! THANKS K. S. Gibson
