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

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. -Aidan B., Elma, NY

I Keep Lucas In Everything I Own.

Just wanted to let whom ever know that I don't usually write reviews. This one out of about ten that I have done in my lifetime. I have been using Lucas fuel treatment for along time (over 20 years). I have a lawn mower that is 22 years old never had the carburetor off of it, still using it to this day. I had a 13 year old $60 Walmart weedeater that still had the original carburetor on it that was never removed(finally wore the motor out and had to get a new one). I have an 2004 Monte Carlo with 230,00 miles that still get 29 mpg. I keep Lucas in everything I own. It works. When I fill up gasoline cans I put it in before I fill them up. -Chris S., Cumberland City, TN

This product WORKS! I highly recommend it.

A month or so ago, I purchased two bottles of Lucas Upper Cylinder Lubricant and Injector Cleaner to try in my 1999 GMC Sierra pickup, which I bought new in January, 1999. For two years I had been trying to solve a problem with the truck. It would be very finicky about starting. If it did not start on the first try, it would flood and then be really difficult to start. More of a problem was that for the first ½ mile or so, the engine was subject to quitting and restarting, in its mildest form, you could say that the vehicle was hesitating or missing. But basically, it was just episodes of "bucking." It was very annoying and significantly made the truck unreliable. That first year, I had the truck in the repair shop off and on for about 3 months. Ultimately, the repair shop replaced the fuel pump in the gas tank. It was about a $550 charge. It did not fix the truck. I continued to drive it, but the issue became worse. Then, one Saturday morning in January this year, following a " rough" drive to the coffee shop, I decided to stop at AutoZone and get some fuel treatment. They recommended your Lucas Injector Cleaner. I filled the vehicle with gas and poured a bottle of the treatment into the tank. It improved substantially, but not completely. But I was encouraged, so after that tank of gas, I filled it again and put another bottle in. The symptoms went away completely and have not returned. So for about $12, this long time problem was solved. Just amazing. Later in January, my 2013 GMC Sierra pickup had the service engine light come on. I had AutoZone check the engine code and it was one that could have several causes, but all had to do with the fuel system creating a problem. I thought, well your fuel treatment worked for the other truck, so I decided to try it on this pickup. Again, two bottles and two tanks of gas and the service engine light went away. Just-amazing. No telling how much money your $12 Injector Cleaner saved me. I am a believer. It is just great stuff. And, it is a minimal cost for potentially solving expensive problems. I highly recommend it. And thanks for putting such a terrific product out for such an cost effective price. GREAT JOB! -Ray Thomas, Burleson, TX

No check engine lights at all and the motor seems to run smoother.

My 2004 Sienna would throw a P0430 code regularly. Sometimes within minutes of resetting the light. I tried the Fuel Treatment and went on a 600 mile trip. I used the Fuel Treatment again at the second fill up. No check engine lights at all! The motor seems to run smoother too. I think I will try to not use it and see if the light comes on. If it does then the fuel treatment really works. Well worth the money for sure. -Ben, Chapel Hill, NC

Thank you Lucas for a great product that performs as advertised!

Just finished a 3250 mile trip in our 99 Dutch Star using Lucas Fuel Treatment for the first time. Added at fill up according to your directions and am thrilled with the results. We are towing a 4500 pound Edge and the coach is at maximum load. Our fuel economy went from the low 8+mpg to 9.9mpg average for the trip! We are powered by a CAT 3216 rated at 300HP. Needless to say it will be added at all fill-ups from now on. Thank you Lucas for a great product that performs as advertised! -Mark N., Edmond, OK

From now on will run nothing but Lucas products in my trucks and cars

First of all let me say I've used Lucas Oil Stabilizer and Fuel Treatment for my Volvo and Detroit diesel engines then switched to Motorkote. Two weeks ago I fueled up and started noticing my truck was getting hesitant and was taking longer to start. Everyday it got worse....10 to 15 seconds to start and it started throwing me injector codes. I figured either I had a bad injector, electrical short or a dirty injector. I was in Denton TX heading home to San Antonio TX when I decided to pour a gallon of Lucas Fuel Treatment in my tanks. About an hour into my drive I pulled over there was no change I figured bad injector so time to get home and head to the shop. When I got home 4 hours later I noticed the codes had cleared and the engine was running smooth and quiet so I was a little relieved. The next morning I was worried because I knew it would act up and I'd have issues starting it. I put the key in turned the switch and she fired right up. I changed the filters, fueled up put a little more treatment in and this engine has been running perfect since. Lucas you have won me over I know your products work and from now on will run nothing but Lucas products in my trucks and cars. -Shawn H., San Antonio, TX

Since we stated using Lucas Oil Marine Fuel additive, we have realized an overall increase in fuel economy in the range of 8-10%!

We learned about the Lucas Oil Marine Fuel additive about 5 years ago and have been using it with great results ever since. We run two heavy duty work boats on a daily basis in harsh marine conditions. Since we stated using this product, we have realized an overall increase in fuel economy in the range of 8-10%! In addition to the fuel additive, we also use the Lucas CK4 oil to which we add the Lucas Oil stabilizer, which allows us to extend our oil change intervals, resulting in substantial annual cost savings. Our boats are critical to our operation and we trust the Lucas Oil products to keep our boats going strong!

All turbo and exhaust brake function has returned to normal saving me at least $1500 to $2,000

My 2008 Dodge Ram 3500, 6.7 Turbo Diesel was plagued with code 0340...sticking turbo vanes. All remedies pointed to turbo removal. After a gallon of Lucas Fuel Treatment the code has cleared and all turbo and exhaust brake function has returned to normal saving me at least $1500 to $2,000. Thank you Lucus! If only more Dodge owners knew. -John I., Tygh Valley, OR

The P0420 code has stopped coming on and my fuel economy has increased.

I never write a review or comment on a product but in this instance I must. I have been using your Fuel Treatment for years. I have a daily commute of close to 200 miles round trip five days a week. I currently drive a 2006 Nissan Altima with over 235,000 miles. With all the mileage I put on cars, I have gotten the dreaded P0420, Catalyst System Efficiency Below Threshold. As a test I tried every product to see if I could get rid of it, clearing the code with my OBDII scanner each time. Nothing seemed to prevent it from coming on. After clearing the code one more time I started using your Fuel Treatment religiously. The P0420 code has stopped coming on. A bit skeptical, I stopped the Fuel Treatment and low and behold the engine light came on and it was the P0420 code. Once again I cleared the code and put the Lucas Fuel Treatment to the test. The engine light with the P0420 code never came on and to top it off my fuel economy has increased. -Marc V., Tannersville, PA

My Mileage Increased…A LOT

This beast was the best vehicle I owned [2005 Jeep TJ Rubicon I-6 AMC 6 speed], yes even over my Ram 1500 Longhorn. After selling my 1993 [Jeep] this was the natural progression for me. Of course Lucas was simply transferred from old Jeep to new Jeep and I anxiously wanted to see the difference the Fuel Treatment would make. Now, with this in the inline 6 (torque monster) what I experienced was completely different. The throttle response didn’t change any but my mileage increased…A LOT. Doing the same trip mentioned above with this Jeep I could make it home on a full tank without Lucas (forgot to buy it before I left…), that was a plus! BUT with having Lucas Treatment it in the tank on the way home, HA! I had a quarter of a tank of fuel left…? I scratched my heading thinking was it windy? The hills different? Did I drive slower? I knew the answer but couldn’t be sure. But after 5 more years of traveling back in for with Lucas in the tank….YES, it was the Treatment that made the difference every single time. - Kyle G., New Brunswick, Canada
