This stuff did wonders on my ’06 Ram 1500.

Jesse M., Williamstown, WV

This stuff did wonders on my '06 Ram 1500. At about 145,000 miles, engine started idling inconsistent. Waited till the tank was about 1/8 full and added the Deep Cleaner then filled up. Drove until I burned up about 1/4 tank truck seemed to run better than it had in years! I now use nothing but Lucas Oil products and recommend them to all my buddies.

It’s running perfect again, after just 20-25 miles of driving! That’s crazy!

I'm a pretty skeptical person. Let's face it, snake oil products have been peddled for hundreds of years. So, honestly, I had set my bar pretty low on good expectations using Lucas Deep Clean Fuel System Cleaner. My car had been running rough over the last couple months, but with the cold of winter, I didn't want to start digging for the problem, so I was just tolerating it. I had a rough idle, and it would develop a lower throttle position dead area, where you had to smash the throttle to get it to develop power again. The symptoms were increasingly getting worse, so I decided to try a fuel treatment. (I still didn't know if it was fuel or ignition, but decided to try the easiest stuff first) Reading over the available products, the Lucas product seemed like the better choice over the others. (we all know that common competitor, that is mostly just alcohol, yuck) So, I put a bottle into the tank, and topped up the fuel. I don't typically drive my car far, usually only about six miles or so, which I'm sure doesn't do it any good. But, and I kid you not, by the third trip, I noticed the low power dead spot was gone! And on the fourth trip, the idle had returned to normal as well. It's running perfect again, after just 20~25 miles of driving! That's crazy! I know the car was going through gas much faster before, and hope to see my fuel economy return as well. I'm still blown away how quickly Lucas Deep Clean Fuel System Cleaner has restored my car to normal operating conditions! Thank you Lucas!!!

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!!!!

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

I drive a 07 GMC Sierra 1500 Classic with 271,000 miles... It was running terrible. I put it on a scanner. Mis-Fire #5 cylinder bad fuel injector. Bought a quart of Lucas Fuel System Cleaner... Added to every 15 Gallons of fuel. It took 4 treatments... But 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.
