My 2004 Mercury Grand Marquis is one of the most trouble-free cars I've ever owned, but the 4.6 V-8 is a notoriously loud running engine and at 30,000 miles, it developed a minor high speed miss. I tried a few bottles of Lucas Fuel Treatment with great results. Not only did I lose the high speed miss, the engine runs much quieter and gas mileage improved noticeably. I use a bottle with every fill-up. I buy it by the gallon and refill the 5.5 oz. bottles so the cost per treatment works out to be about $1.00 each.

I recently purchased my 2007 Ford F-150 XLT Super Crew and I am happy to report that the Lucas Fuel Treatment and the Synthetic Oil Stabilizer are the best products I have found and used. My truck is very quite while idling I have to look at the RPM gauge to see if my truck is still running. Also my truck runs smooth in cold and hot weather. When I put the pedal to the metal the response that I feel, hear and see is purely awesome. This is one dedicated Lucas customer/product user, I want to see what my engine looks like at 100,000 I can almost say it will be as good as when I first bought my truck. By the way I see a 4 miles to the gallon increase I am at 22 miles HWY versus my 18 miles HWY. Lucas makes good products that deliver awesome results that work!

I have just used Lucas Fuel Treatment again after a few months of trying other bands and I noticed a difference the same night. I get better mileage with a smoother and more accelerated throttle response. Used it on my 02 Lancer and I had good results too. I am now buying Lucas by the Gallon, saving money and gaining performance benefits all in one.

Your fuel treatment ROCKS, I have used it for about a year now in my 1999 Chevy Silverado 4*4 with 91000 miles. Before I started to use this "wonder drug for gas eaters" I would get about 12 to 13 mpg town and highway it didnt matter what I pulled or how I drove..So I tried some of my fathers Lucas Fuel treatment he uses in his semi. I didnt check the miles when I did it, so I filled up my pickup and added it. "WOW" NO MATTER HOW I DRIVE 16 M.P.G I was thinking that was great..I drove it for 6 months that way. Last week I bought a K&N filter for my 99 chevy filled the tank and drove, I filled after a half of tank was gone...AND I THOUGHT THE 16 M.P.G WAS GOOD...OH NO NOW IM GETTING 18 M.P.G Yes it went from 12-13 to 18 AWESOME, I have a 07 chevy colbolt that I am now going to do the same treatment to it. It gets avrg.30 now..Who knows what this will bring 35..40?

I have a GMC truck with a Vortec engine that is known for having clogged injectors. I had used several different cleaners before I tried your product. When I added your fuel treatment, the results were almost immediate. I began adding it at every fill-up to keep from having injector problems, and it was very effective. I recently pulled the engine to replace a leaking intake manifold gasket and other leaking seals. To my total amazement, when I pulled the intake manifold and took a look at the intake passages and valves, there was NOTHING! Not a speck of varnish or carbon on the valves or passages. Just gray metal intake valves and shiny aluminum on the manifold! The valves looked like NEW! I'd never seen clean intake valves on any engine with 170000 miles before. I'm sold. I'll keep using this product in all my vehicles.

Check engine light was on and needed to get emissions test done. Was told by a technitian to add a bottle of lucas fuel system cleaner. After two weeks while driving on the highway noticed the check engine light was off. Went for an emissions test and passed with flying colors. Thank you Lucas Oil for a great product that works.

I own a 1994 GMC Suburban with 183K miles on it. It recently started running real rough and would not stay would not idle. I would have to hold the brake and gas pedal at the same time in traffic. I was averaging 12-13 MPG. After adding Lucas Fuel Treatment, my truck now idles and drives better than it ever did. And I also Average around 18-19 MPG!!!! Now thats amazing coming from a Suburban. I am a customer for life now. Thanks Lucas for saving me money and helping me get my truck running better than ever.

I have used it in my 1996 Honda xl600r and have had great results for many years. Keeps my 2002 Ford Explorer running just great. You really can see the results in MPG and both my bike and truck just run at their best with it added. Your products are just the best and work up to your name each time. Anyone who is thinking of using Lucas products you just can not go wrong with Lucas they make the the best products and keep you running at your best.

My Olds has 145000 miles on it. I am always having issues with clogging fuel injectors. I have tried everything on the market for fuel injectors and after the first bottle of Lucas I'll never buy anything else. My car runs like new. I notice more pick-up, better starting and no more missing. I add a bottle (8OZ) every other tank of gas. Your product does everything you say it will. I am very happy I found Lucas products, they are superior. Thank you! Brian Tinman, Illinois
