HEAR IT FROM OUR CUSTOMERS

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

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!

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

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.

It is running better now at 276K than it did at 40K!

I recently purchased your Deep Clean Fuel System Cleaner. I have always had problems with fuel system on my wife's 2002 Ford Escape as it seems to get gunked up very quickly by the 10% ethanol in gas. I have had to replace some expensive componets directly and indirectly related to the fuel system. Anyway, I poured a bottle of your Deep Clean Fuel System Cleaner into a full tank of gas and my wife drove it for the week running all the fuel through until the fuel light came on. Last weekend I took it to run an errand and could not believe the difference. It is running better now at 276K than it did at 40K! The idle is steady, so steady that several times I wasn't sure if the engine was running or not. It runs so smoothly now and accelerates much better than it ever has. It is now possible that I will be able to keep this vehicle for at least 50-100k longer. I will be using this on my other 2 vehicles as well. Thank you for a superior product! Best $10 I ever spent!

Now my car runs like new.

I have a 2002 Honda Odyssey. The engine was surging in idle anywhere from 800 rpm to 1300 rpm. I went to the auto parts store. Bought Lucas fuel system cleaner. Stopped at the gas station with a 1/4 tank. Put the Lucas in. Filled the tank. Now my car runs like new. Smooth, normal idle. It was that easy!
