Now my car runs like new.

Chris K., FL

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!

This Has to be The Best on The Market And Especially The Price

Randy F., Whittier, CA

I have a 2006 5.4 F-150 with 211,000 miles. My truck was running so bad the check engine light came on and I had to replace two coils it did help but it still ran really bad. I use one bottle of Lucas injection cleaner and within a 1/4 tank I noticed a big improvement, after I went through full tank my truck ran great, so I filled up another tank full of gas and Lucas injection cleaner, Wow truck runs so smooth and no hesitation this has to be the best on the market and especially the price. Thank you Lucas oil you saved me loads of money!!!!!!!

Now my check engine light is off and truck is running great.

I will recommend this product to all my friends who are looking to get the most out of their vehicles. Thanks for a great Product.

It is like magic… This stuff is amazing!

One bottle of the Deep Clean Fuel System Cleaner saved me hundreds of dollars in repair costs. The engine in my 2003 Cadillac DeVille was idling roughly and misfiring. Two days ago, when I tried to start it in the morning, the engine idled so roughly that it stopped each time I took my foot off of the accelerator. I was dreading a trip to the mechanic, down time, and rental car costs. I nursed the car to the local auto parts store, bought one bottle of Deep Clean Fuel System Cleaner, and poured it into the gas tank. Presto! Before I was finished driving the car home it was running better. After a few more miles the engine was not stopping when it idled. Today, two days later, the engine is running more smoothly than it has in over a year! It is like magic. The car has more power and zip and the engine is now very quiet at idle. This stuff is amazing!

Thanks for making such a great product.

Yesterday I noticed that my 2013 Jeep Patriot was driving kind of sluggish so I read up on what could possibly be the problem so I purchase your product (fuel cleaner) so before I filled up my tank I poured the cleaner in my tank and I noticed the difference immediately my car started running a whole lot better. I'm forever grateful for your product from now on it's the only fuel cleaner I'll ever use. Thanks for making such a great product.

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!

Lucas Deep Clean Fuel System Cleaner Does The Trick for F-650 Work Truck

Michael M.

My work truck, a 2014 Ford F-650 V-10 with only 20k miles started running very poorly recently. The engine was running roughly, the CEL was almost always on, there was an ammonia smell from the exhaust, plus it would emit a cloud of white smoke that smelled like unburned gasoline a few times a day. Power was way down. The exhaust emmisions even caught on fire TWICE! It was into the Ford dealership twice where they changed the O2 sensor, the catalytic converter and the air filter, all to no avail at all. Yesterday I decided to buy a bottle of Lucas Oil Deep Clean Fuel System Cleaner. I put in the bottle this morning, then filled the gas tank and started my work day. Not only are ALL of the abovementioned symptoms completely now gone, the truck is getting about 1 mpg better gas mileage, which is huge, since it was getting 3 mpg before. Thank you Lucas! Can't wait to tell my employers how "I" fixed their truck!

WORKED LIKE IT SAID AND SAVED ME $300+

Recently and all of a sudden, my 2003 Honda CRV began to drag and stall. As a single female, I had no idea where to begin. I called a mechanic, who wanted to charge me over $300 to fix the problem...WHAT?! NEXT, I made a trip to my local automotive franchise; while there, he connected my vehicle to the diagnostic computer and told me that it was a catalytic converter issue. He the recommended that I use some form of " Cat Cleaner". Ok. As I stood at the wall of various THIS AND THAT... completely confused, with one oil looking just like the next one. I remembered from some many years ago, the name LUCUS OIL was the best. I picked up a bottle of the $10.00 DEEP CLEAN FUEL SYSTEM CLEANER. WORKED LIKE IT SAID AND SAVED ME $300+ for now!!!! I'M SOLD ONLY LUCUS FOR MY HONDA!!!!
