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!

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.

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 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 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!

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.

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.

My 2001 Honda was stalling every two minutes. I went to my mechanic, he said he was way behind on some cars that he wouldn’t be able to see my car until tomorrow. He gave me a small bottle of your fuel injector cleaner. Told me to pour it in the gas tank an drive it for 10 – 15 minutes… It was running smoother then silk after about 10 minutes.. I had never seen a additive of any sort actually work. I put a bottle in each of our cars once a year now. Thanks!

I own a 2004 Porsche Cayenne and have 348,000 miles. I contribute the high milage on this vehicle to the use regular Lucas gas additives. Nobody believes I have that milage on it and I tell them all to use Lucas!

I have 5hp Honda engine mounted on a log splitter which are notorious for sticking intake valve, cannot get engine started unless you pull valve out and clean. I use 1/2oz.of Lucas Fuel Treatment in every tank of gas, no more sticking valve, it works great.
