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 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!

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 own a 2008 Ford F`50 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.T his 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

I was amazed at the change in my SUV, I have a 2002 GMC Envoy with over 230,000 miles. I love my car because of the options it has. I put this in my SUV every other fill-up and you can tell the difference in the way it idles smoothly plus it doesn’t hesitate when I accelerate. Thanks for the Lucas High Mileage Fuel Treatment, great job.
