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.

4 days later I was shocked when it passed the emissions with no codes.

Matt L.

I purchased a 2007 Chevy Avalanche and almost immediately the check engine light came on. I ran a code scanner on it and said that P0430: Catalyst System Efficiency Below Threshold (Bank 2). I thought for sure I was replacing a Cat or at least O2 sensor. I read up here to try the Lucas Deep Cleaner first. I had to do emissions on it so I gave it a try. I immediately threw in a bottle and it cleared the codes and 4 days later I was shocked when it passed the emissions with no codes. I used Lucas before and will continue putting a bottle in every 4000 miles.

I put in another bottle of Lucas and it has run perfect ever since!

Robert S., Grand Marais, MN

I had been noticing that the RPMs on my 2003 Dodge Dakota were randomly fluctuating. It seemed to be only at highway speeds above 50MPH and while idling in park. My wife and I were on a short road trip and the truck got really sluggish. I stopped at a gas station and after checking out the different automotive products I bought a bottle of Lucas Deep Clean Fuel System Cleaner. I poured it in the tank, got in the truck and my wife said, "What the heck did you put in the truck?? That noise it was making stopped!" Within 20 seconds of pouring it in the gas tank my idle evened out! Down the road again and the RPM bouncing was minimal! At my next full tank fill up I put in another bottle of Lucas and it has run perfect ever since! Thank you so much for developing such an amazing product!! I'm a Lucas customer for life now!

This stuff did wonders on my ’06 Ram 1500.

Jesse M., Williamstown, WV

This stuff did wonders on my '06 Ram 1500. At about 145,000 miles, engine started idling inconsistent. Waited till the tank was about 1/8 full and added the Deep Cleaner then filled up. Drove until I burned up about 1/4 tank truck seemed to run better than it had in years! I now use nothing but Lucas Oil products and recommend them to all my buddies.

It’s running perfect again, after just 20-25 miles of driving! That’s crazy!

Rod R., Nanty Glo, PA

I'm a pretty skeptical person. Let's face it, snake oil products have been peddled for hundreds of years. So, honestly, I had set my bar pretty low on good expectations using Lucas Deep Clean Fuel System Cleaner. My car had been running rough over the last couple months, but with the cold of winter, I didn't want to start digging for the problem, so I was just tolerating it. I had a rough idle, and it would develop a lower throttle position dead area, where you had to smash the throttle to get it to develop power again. The symptoms were increasingly getting worse, so I decided to try a fuel treatment. (I still didn't know if it was fuel or ignition, but decided to try the easiest stuff first) Reading over the available products, the Lucas product seemed like the better choice over the others. (we all know that common competitor, that is mostly just alcohol, yuck) So, I put a bottle into the tank, and topped up the fuel. I don't typically drive my car far, usually only about six miles or so, which I'm sure doesn't do it any good. But, and I kid you not, by the third trip, I noticed the low power dead spot was gone! And on the fourth trip, the idle had returned to normal as well. It's running perfect again, after just 20~25 miles of driving! That's crazy! I know the car was going through gas much faster before, and hope to see my fuel economy return as well. I'm still blown away how quickly Lucas Deep Clean Fuel System Cleaner has restored my car to normal operating conditions! Thank you Lucas!!!
