I am a pilot in the United States Air Force and I fly the F-117 Nighthawk. I was very skeptical about Lucas until I a fellow pilot in my squadron recommended Lucas UCL injector cleaner. I noticed a 2 Mile Per Gallon increase in economy and a smoother running BMW. I will stop using 'other' fuel injector cleaners that are all HYPE and stick with Lucas. Thanks for a great product.
