After Pouring The Treatment Into My Gas Tank I Started To Feel The Difference

Aidan B., Elma, NY

This product works. After using the fuel treatment for my 2008 Ford, I can feel the effects. My car has 100,000 miles on it and after pouring the treatment into my gas tank, I started to feel the difference. I would highly recommend this product.

Great stuff!

John M., Delta, MS

Great stuff! Use it in my 1990 dodge W-250 pickup Cummings equipt. I’ve got 850,000 km on her and never had to have the injectors cleaned since I started using this product. First used it ten years ago under advice of a friend, never will not use it again, more affordable than “other” products on the market and you know for sure, if it’s got the Lucas name on it, it’s a good product. Thanks for the engineering on this product Lucas!

I have used Fuel Treatment at every fill-up

Michael H., Topeka, KS

Have a F-150 purchased with 35,000 today I have 250,000 and have used Fuel Treatment at every fill-up have only needed to change plugs two times no problems with fuel injectors, actually I have had no problems with any part from the fuel pump to the exhaust system. I still pull my 16 ft. fishing boat to reservoirs far and near. I also still drive to my daughter's house 2,000 miles every year. It's my daily driver.

Our mechanic has mentioned that our cars run great due in part that we use the Lucas products.

Chris R.

I have 2 VWs, a 2004 Passat 1.8LT Tubo with 271,000 miles and a 2009 VW Tigaun 2.0LT with 156,000 miles. Both cars are running great, and one of the reasons is because every 10th fill up we add the Upper Cylinder Lubricant and Injector Cleaner. Our mechanic has mentioned that our cars run great due in part that we use the Lucas products. I recently met the [Lucas] National Sales Director and he was kind enough to explain how the product works at keeping the fuel system clean. Keep up supplying great products.

I want to say your products are amazing.

Louis O.

I want to say your products are amazing. I have a 95 Toyota 4Runner with the 3.0 V6 and the car is very sluggish on Hills especially when towing my boat. I went fishing and put a bottle of Upper Cylinder Lubricant in the gas tank on the way up and one on the way down. Well, now that I’m back the car now has more power and better fuel economy. I was very impressed and now use it on a daily basis. The car has over 203,000 miles on it and it runs better than its ever been. My next experiment is your oil stabilizer in my dads truck. That’s a 89 Toyota pickup with over 281,000 miles on it and it will hopefully take away some of the knock and help the 20w-50 weight oil flow better in the cold mornings. So thank you Lucas Oil and I plan on buying more of your products!

It’s the best product on the market!!

Jim R., Tahlequah, OK

I use Lucas Upper Cylinder lubricant at every fill up in my 1997 Ford Ranger. It's the best product on the market!! I get improved fuel mileage and easier startups and no hesitation, especially when accelerating onto on ramps and when passing. I also like Lucas Slick Mist in between waxings.

Within a half hour my gauge started working again.

Stephen H., Redlands, CA

I started using the Lucus fuel conditioner [Lucas Fuel Treatment] when my fuel gauge in my Ford diesel truck got stuck. I was told by a friend to use it for this purpose, and within a half hour on the road after using it my gauge started working again. If you use it for nothing else, just solving this problem alone is worth it.

I’ve used Lucas injector cleaner on my 2007 chevy Impala with good results.

Robert N., Balaton, MN

I've used Lucas injector cleaner on my 2007 chevy Impala LT 3.9L v6. Good results. Even today I was going up a step grade and before it would always down shift going up. Well today it didn't shift down to a lower gear at all. And you could hear it with that low tone of steadily going up the hill. Always use this injector cleaner from Lucas by the quart or gallon. Then just add a portion to a 3 oz bottle to add to a fill of gas.

I can definitely feel the difference…

Gus G., Chandler, AZ

I use the Upper Cylinder Lubricant with Injector Cleaners product every time I put gas in my 2013 Harley Davidson Ultra Classic. I can definitely feel the difference after 1/2 bottle of this in there. Bike usually feels sluggish in warmer temps; always ran real good in cooler temps; but with this stuff, runs just as good in warmer temps. Pulls hard too. Not sure what's in this stuff; but it works!

Lucas Fuel Treatment Gives Tacoma 6+ MPGs

Mike O.

I have a 2013 Toyota Tacoma and I put 25K miles on my truck a year, I started using Lucas Fuel Treatment about four months ago and my performance and mileage has really gotten better, I went from 23.5 mpg to 29.65 as of this mornings fill up. I was a skeptic but I have measurable data that proves it out. Great product, I run in all three of my vehicles now.
