I use Lucas Oil Deep Clean Fuel System CleanerIt is the best stuff i have ever used. I wish I could afford it more often, but man, this stuff works great. The cost totally compensates for the way it works.thanks so much.

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!

Dave's 88 Jaguar XJS V12 had a rough idle until Lucas Deep Clean fixed it up

Hi, I just bought an 88 Jag XJS V12. The car had been run but not driven in a few months. It idled rough at first but tightening the loose throttle linkage and cleaning and resetting intake leveled it out. The idle was still low and unless you press the throttle slowly there is a hesitation, sometimes it even stalls. The fuel pump and filter are new, so I checked those off the list. I pulled the plugs and the base rings had quite a bit of carbon on them and I planned on replacing them. I was also concerned about my injectors. The cost of a simple tune up like replacing spark plugs and injectors on a Jaguar V12 is astronomical compared to a $12 bottle of your \Deep Clean Fuel System Cleaner\ so I got some.  This stuff really works! I put it in last night, ran the car for about 20min and again for about 10min today. I didn't even drive it yet, maybe hit 3,000 rpm a couple times. I pulled a  couple plugs tonight and you can already see where its cleaning carbon deposits off the base ring. I'm sure my injectors are loving it too! The idle is already closer to where it should be and the hesitation is less prominent. I'm confident it will only improve once I can drive it around. I've already recommended it to all my friends.

Thank you Lucas Oil for another great product!Dave Fullington

Bobby Taylor Uses Lucas Deep Clean To Overcome The Ethanol In His Local Fuel Supply.

I have an older Ford Taurus, runs ok. Just recently it started choking at startups and at lights.  Never done that before, autoparts clerk said they were using ethanol in the local gas he found out. He recommended Lucas gas treatment, I poured some in, and have not had a problem with rough starts or idles since.

Stephen R. DeBence Describes Lucas Deep Clean as \Magic\ Liquid Cleaner for the Fuel System

Dear Sirs;I am writing your company, after using your Fuel Injector Deep Clean new product. We purchased it at: Kragen-O’Riley Auto Parts Store in Murrieta. The young store clerk said “It was so new that it was not on the shelf yet and he would get a bottle from the stock room. He said it was terrific and sold most of it already. “ (I was ready to try something after no luck in start problem.)Here is the full story: We have a ’96 Ford Windstar 3.8L V6 with 177,000 miles on her, used in our business, driving all over the country. Last week, NO START!! We had the fuel pump replaced and a couple of relays, new ground wire for the computer. It started but very hard, almost killing the battery. Once running about close to normal… in the 17F. to 40F. mornings of last week: No start. After battery charge and some bad words, we got her running but were afraid to go any distance.We purchased a bottle of your liquid “MAGIC” as mentioned and poured it in the ½ full tank (12 Gallons) right in front of the store. Within ten minutes the engine gained power and at the stop light, it ran so smooth I thought it had stalled out!!!!! Wait, there is more….. When I drove home (ten minutes), I let the engine run for about another ten minutes at about 1,100 RPM to charge the battery up for a good start the next morning.You would not believe this. Next morning, 18F. I turned the key to start the car and in an instant the engine started!!!!! I thought I was dreaming. I warmed it up and the engine was running so smooth. Never like this before…… Well, I thought I would shut it off and see if it would start up again. In an instant, and running again! I drove the van myself on some business calls and put another half tank of gas in and another bottle of DEEP CLEAN.

Almost a week gone, the van starts and runs great. I am sure you know as I do now, that the injectors were carbonized, leaking and sticking. Well they are almost as good as new (about $400 a set). I am still going to change the sensors after 15 years. We were stumped, because everything checked out, Spark, Compression, Timing, Injector Pulse, Fuel Pressure, Ect. I have never written anybody in my life about their products, but I am writing you and I wish to thank you for this wonderful liquid cleaner. You have my best regards and I will be using Deep Clean once a month, FOR SURE!!

After previous 40 years in the Auto – Aircraft – Gas Turbine and Electrical / Electronics Business, I take my hat off to you!Best Regards,Stephen R. DeBence

Jaime Obando Uses Fuel Treatment in '79 BMW 528i

I'm grateful for your product. I drive a 1979 BMW 528i with more than 150K miles and my fuel injection system was pretty clogged...even after replacing the fuel filter, fuel pressure regulator and even using higher octane gas on a daily basis the symptoms did not improve. It was only after I used your fuel treatment that I began seeing dramatic improvement in the acceleration of the vehicle and overall performance of the car. I'm also grateful for the oil stabilizer which reduced oil consumption in my old engine by as much as 70%!! I now plan to use the synthetic oil on my next oil change and hope to improve mileage and viscosity on my old 1979 BMW 528i!!

Carl Hopkins uses Lucas Fuel Treatment for '93 Pete


My name is Carl Hopkins. I've been driving since 1976. I just got my own truck, a used '93 Pete. I was having problems with fuel filters and oil leaking. Friends told me about Lucas Oil Products but I still did not believe in it. Until I was in the desert and my fuel filter problem was getting 3 miles to the gallon of fuel. I changed one filter but could not get the other one. I bought fuel and another driver said to put Lucas Fuel Treatment in the tank, so I did! It cleaned it up and I was now at 7.25 miles per gallon. What good STUFF! If your treatment can do this to the fuel, I thought what can your product do for my engine. So I changed the oil and put Lucas Oil Stabilizer in it and I could tell the difference right away. Thank you for Lucas Oil.
