I own a 2002 Nissan Frontier "Desert Runner", 5 speed, 6 cyl., 2WD, currently at 97K miles. EPA estimates on vehicle: City = 15 MPG, Highway = 17 MPG I track my gas mileage on the computer every fill-up and burn 87 octane gasoline from Texaco, Valero, or Shell. Started using 3-4 oz. of Lucas Fuel Treatment every fill-up in January 2008 with ~86K mile on the odometer, and at that time was averaging 17.2 mpg. As of July of 2008, I am averaging 20.3 MPG on the same vehicle, same driving habits and trip, and with ~97K miles on the truck. This, for me, is a "trip and a half" to my work (about 45 miles) for free each tank full, based upon gas usage prior to the Lucas.

my dodge was using 2 qts of oil between changes. after using lucas stabilizer it is now using a half qt. good product.

I recently bought my F-250. It had 260,000 km on it. The engine idled a bit roughly at stoplights when warm, was otherwise fine. I changed the fuel filter with little effect. I then tried several other "Fuel System" products, including the cleaner/anti gel I normally run in my Volvo Semi Truck in winter. There was a bit of improvement but I wasn't happy and thought I needed a new injector. Last week I bought a gallon of your product on sale at a truck stop in Washington State. I put half in my Tractor's tanks, and then filled the bottle again with diesel fuel. I poured this 50/50 mix into the tanks of my Ford, and by the time I'd driven 60 miles, it idled smoothly and cleanly. I've fueled the pickup several times since then, adding your product only every second fill and it still runs smoothly. I normally never write testimonials, but you saved me a lot of money and grief

Panic! occured when my check engine light came on, go a reading on my car which stated my Throttle in my car was dirty, 1)mecahanic told me the whole gas tank would have to be cleaned out ??? another said he'd have to check to see what's wrong (I already knew) and another told me I would have to replace the whole Throttle. But the last mechanic said I could do a treatment myself and the man in AutoZone directed me to what he said was "The Best" on the shelf. Needless to say soon as I gave Henry (that's my car's name) his gas treatment the light cut off no sooner than the gas started flowing. Me being a woman not knowing much about cars learned to shop around but now I know about this great line of products to which I will live by for the life of my car. THANK YOU LUCAS OIL

Well I'll be dipped in mud! Your product works like a charm. 136000 miles and the trans started to slip. I thought I was looking at a two to three thousand repair job or replacement. I want to keep the truck because everything else is in such good shape. What did I have to loose except a few bucks anyway? I removed an equal amount of exsisting trans-fluid and replaced it with your magic elixer and BAM!!! less than a mile down the road when I did a road test the problem was solved. Today I gave the truck a real workout and it actually runs better than it has in the past year. Great product guys...maybe your not charging enough for it, you saved me a few grand. Thanks. Keep up the good work.

just to let you i was not much of a beleaver in you products ,, i took a trip to readding calf , from tucson and i put your turn up in a bottel in my tank 2 times and beleave me i got 30 miles a gl in are crv and i have told people how will it works and they now are using it thanks

I was recently at the NHRA Powerade /TORCO Nationals in Joliet IL. We were sitting near the 1/4 mile mark when I noticed part of the LUCAS Crew nearby. I could'nt walk away without telling them about my Isuzu-Resurrection project. I was talking with "Terry" about the Trooper I bought 2 years ago. 1998 Trooper with 155,000 miles. The quy I bought it from said, "It will go a long way, but you have to watch the oil." I come to find that really all Troopers "use oil" "You will go through one quart every 500 miles, so just check it, and fill it."

I just drove 190 miles on the same amount of gas that I used to go 120 miles on. I've been riding my bike for years and have always got about 120 miles on a tank. After completeing 3/4 of the small bottle over a 1000 mile trip, my bike gets 190 miles per tank, Amazing!! Plus it runs about 10 degrees cooler. I'm telling everyone! I'm a believer now. Thanks for making a great American product.

I am thankful that a few people in the auto parts store recommended Lucas Transmission Fix for my car. The car runs great....was running great. Saturday...things were fine, Sunday...not so fine. The tranny was taking forever to change from first to second and second to third. Monday, I stopped by an auto parts store in Hurley and was talking to the salesman. Two guys behind me, as well as the salesman, all replied at the same time to get Lucas Transmission Fix for my problem. I added it as soon as I left the store. I live 15 miles from the store. Before I got home...the car was running smooth again! Thanks for having a Great Product that everyone uses!
