I’m a customer for life

I used your ethanol fuel conditioner back in the October of 2022. I dumped half a bottle of it in the tank full of E85 and let it idle longer than normal because I was checking for leaks. No leaks and off I went across the street to my neighbors. Unknown to me right after I put in gear the rear main seal blew dumping oil all the way down my drive and all the way up my neighbors drive. Once parked I saw smoke coming up through the hood, I jumped out looked underneath and saw flames. Oil from the seal got on my crossover pipe and started the fire . We extinguished the flames out quickly and in disgust I parked the car in my barn for the whole winter and spring. After replacing the rear main seal I fired up my turbo 6.0 LS and purred. So about 10 minutes of runtime with your product saved me from the hassle of removing my injectors and cleaning them. I'm a customer for life. Thank you Lucas Oil!

Use it folks, it’s really a good product

Hi, I have a 2009 Volvo s60 2.5t awd and last week I had check engine light on and a code ECM 2900 fuel pressure vale fault, I thought is the problem was connected to the Fuel pressure sensor and I ordered one, in the same time I added when I filled the tank 200ml. of Lucas injector cleaner. I made a trip of 300 miles on Sunday. Today the check engine light is gone, so it was the fuel pressure valve, problem solved. The Lucas injector cleaner works. Use it folks, is really a good product. Val

I use Lucas Fuel Injector Cleaner upon every fuel fill up

Garry, R, Hamilton, OH

Hi, I am from Hamilton, Ontario in Canada. I own 3 wagons, 2 are Dodge Magnums and a Mercedes-Benz C300 4MATIC Wagon. My Magnums are both 2005, and my 2.7L just turned 308,000 km. I use Lucas Fuel Injector Cleaner upon every fuel fill up, and the car purrs like a kitten, runs like new! My other Magnum is the 5.7L HEMI Engine, and just turned 145,000 kms, same Lucas Oil Fuel Treatment, car runs like new. My 2018 Luxury Mercedes-Benz gets the Lucas Oil Fuel Injector Cleaner as well every fuel up, and with only 25,000 kms, I know I am in good hands treating all three of my cars fuel sytems with LUCAS OIL FUEL INJECTOR TREATMENT! Great Product!

I highly recommend you give it a try in your Diesel engine

Rob H., Caldwell, ID

I use Lucas Upper Cylinder Lubricant religiously in my 2000 F350 with the 7.3 Powerstroke. The first time I tried it, I immediately noticed my diesel engine ran smoother, and quieter. After running just one tank of treated fuel, I noticed it actually increased my fuel mileage. This product absolutely more than pays for itself with fuel savings alone. I average an additional 50 to 75 miles range with a 36 gallon tank of treated fuel, over non treated fuel. I use 11 oz. of Lucas upper cylinder lubricant with every fill up. I highly recommend you give it a try in your Diesel engine.

My mileage is now back where it was and the engine is smoother.

I recently replaced the fuel sending unit in my Xterra which Nissan would not cover. I just came out of the warranty by a few miles. First tank, my mileage was off by 30 to 40 miles. I pulled the battery cable to reset the ECM. I was only off by 20 to 30. I went and got some Lucas and poured it the tank. My mileage is now back where it was and the engine is smoother. This is good stuff. It blows away anything else in a bottle.

I wanted to thank you for such a great product in your Lucas Fuel Treatment.

I wanted to thank you for such a great product in your Lucas Fuel Treatment. I ran an impromptu experiment when I took a recent trip from Texas to PA. Starting out without Lucas running 89 Octane gas in my 2005 Chrysler minivan, I was barely getting over 19 MPG. I bought 4 bottles of Lucas and used it with every tank of gas on the way up to PA. I saw steady MPG improvement and by arrival, I had achieved a consistent 23 MPG. On the way back, we achieved between 24 and 25 MPG consistently for each tank of gas. What an impressive product. Thank you very much!

Over 500,000 miles thanks to Lucas Oil Products.

Just wanted to let you know that my boyfriend swears by your product he has a 1995 GMC truck and with every oil change he uses your product his truck has over 500,000 miles I think that is a good testimonial, just wish I had done the same.

I am amazed at what it has done to my engine noise.

Jim T., Grand Rapids, MI

I own a 2008 Ford F150 with a 5.4 engine and 137,000 miles. Over the past year my engine developed the Ford death rattle. It's known as cam phaser problems. This was when pulling a trailer at low idle. I decided to try out Lucas High Mileage Oil Stabilizer additive. This was 12,000 miles ago, and I am amazed at what it has done to my engine noise. It's been gone since a week after I started using it. I told my son in law about it, as his Honda engine is using oil and fouling plugs. He is amazed at how it has helped his engine trouble and he has not fouled a plug since he started adding it. I also have added it to my old Briggs and Stratton 5 hp engine. It smokes really bad, since adding it has cut it down 80 percent. It has made believers out of us. Thanks
