Rick Simoneauz uses Lucas Oil Stabilizer in 1999 Freightliner

I have a 1999 Freightliner. I have been using Lucas Oil Stabilizer from day one. Started with 1 gallon every change (12,000 miles). When I got 500,000 miles on the truck I increased to 2 gallons every change. Now I have over a million miles on the truck. I use 3 gallons every change and managed to increase to 15,000 miles between changes. I started using your fuel treatment about 600,000 miles ago using a gallon about two times a week. Now I use one gallon every time I fuel. It has increased my mileage from 5.2 to 6.7 on an average. Can’t say enough for your product. It has kept my rig running all these miles and still don’t use any oil between changes. I also have never had any major engine work done. Too bad you people don’t make tires. I would never have to replace anything.

Thank you,

Paul Carson uses Lucas Heavy Duty Oil Stabilizer 1997 Olds Cutlass Supreme

About three weeks back, I heard of your product and decided to give it a try. A few days ago my wife called me at work and told me she thought she had a problem with her car (the Olds), said the oil was real full and looked like it had coffee creamer in it. I am a mechanic and just knew that my engine was ruined. I asked her if she drove the car with the oil like that and she said she had driven it home from downtown. I was afraid my engine was trashed. Thanks to you Heavy Duty Oil Stabilizer, no internal damage. Thanks for your product I will never again be without it.

Jim Aldrich uses Lucas Heavy Duty Oil Stabilizer in 1991 ford ranger 4 cylinders

While driving through Atlanta, Georgia w/150,000 mile on my truck my oil pump went out and I drove the truck 700 miles home to Wapakoneta, Ohio with no oil pressure at all. Took off the pan, inspected all bearings, installed new oil pump and continued driving the truck for another 25,000 miles when I sold it and bought a new truck. The Ranger was sold to one of my employees who still drives it today.

Jerry Canfield uses Lucas Heavy Duty Oil Stabilizer in 1979 Dodge B300/Huntsman Motor Home

I was traveling South on US Hwy.441 over the Smokey Mountains from Gatlinburg, Tenn. towards Cherokee, NC. a half mile from the top of the up hill climb toward the state line of TN & NC, My motor home completely quit pulling, smoke came out from under the motor home, at the time I could not go forward or backwards, I was about 200 feet from a pull off and after a short prayer, I put it in Low 1, and it pulled it off the travel lane of the road, an hour and a half later I started the engine and proceeded toward the top, once at the top on level ground, I checked the fluid level, it was a couple of quarts low, the relief pop off valve released the pressure built up in the trans from the high temp and lack of any type of external transmission fluid cooler, so I had 1 Bottle of Lucas Automatic Trans. Fluid additive, I added it, prayed and headed toward Cherokee, NC. Once in Cherokee, I purchased another bottle of Lucas Trans. additive, and a couple quarts of auto-trans fluid! Brought the level up to the recommended level, and continued the 300 mile drive back home to Middle Georgia! Thanks for such a wonderful product as are all your Lucas additives!

Glenn Thorson uses Lucas Heavy Duty Oil Stabilizer in '91 Eagle Talon Tsi

I bought this Talon almost on impulse. Great shape, but had been sitting for almost three years. Ran great when I test drove it, but on the way home it started to smoke like crazy, I thought I'd been had. Too late to take it back I decided I could live with it. I heard from some guy in a parts store that he had the same problem in a corvette he bought and that he had used this Lucas "stuff". Stopped smoking almost instantaneously when I put the stabilizer in on my next oil change, great stuff. I also use your transmission fix and the injector oil.

Matthew Lange uses Lucas Heavy Duty Oil Stabilizer in 1979 Ford f150

After being parked for 5 years because of low oil pressure (5psi at idle and 15psi cruising) and after replacing the oil pump and the main bearing, the previous owner was willing to sell it cheap. After bringing it home, I changed the oil, added 2qts to the 7qt system and now have 15-20psi at idle, and 30-35 cruising. I also have added the steering, fuel system, and transmission additives with great results. This is one product that does what it says, and does not put harmful additives into my engine like Teflon. Keep up the good work!

Mykel Atkinson uses Lucas Heavy Duty Oil Stabilizer in 1982 Chevy 1-ton

Lucas Racing products are a worry free product. It's nice to know that when you pour something in you engine that you know what it is and that it will work. I have used the Heavy duty Oil Stabilizer in used and new engines. The result is the same protection and longer engine life. Thanks Lucas Oil Products for your wonderful products.

Lance Markell uses Lucas Heavy Duty Oil Stabilizer in 88 Mustang GT convertible

I have an 88GT with 7,000 original miles. I thought it would be to my advantage to change the oil and use Mobil1 synthetic. Unfortunately, the car started to leak oil due to the cleaning properties of synthetic. However, I didn't appreciate the oil leak so I changed back to dino oil (regular oil) and added 1 quart of the Lucas oil stabilizer along with 1.5 oz of brake fluid and the leaks have been significantly reduced. I think that they will stop when I drive the car in the spring. I will add it to my Saturn at the next oil change.

Adam uses Lucas Heavy Duty Oil Stabilizer in 1986 Chevrolet Celebrity

I just want to say that Lucas is officially the only oil/steering/fuel/transmission additive I believe in. With so many additives available, it's hard to know which ones to trust, but I've used the Oil Stabilizer, Transmission Fix, Steering Stop Leak and the Fuel additive, and every single one of them had a major effect. My oil stopped leaking, the engine stopped burning oil. My transmission shifts more smoothly. My fuel economy/performance went up. The steering additive lets me top up my steering every two MONTHS compared to the two WEEK intervals I was topping it up at before. I will never use another additive in anything I own. Lucas is an amazing product. Well done!

Rachel Twine uses Lucas Heavy Duty Oil Stabilizer in 1987 Mazda B2200

My 1987 Mazda Pickup was making some lifter noise. It is a fairly common problem, and since these lifters only had about 50,000 on them, I didn't want to replace them right away. I tried the Lucas Heavy Duty Oil Stabilizer and all ticking has ceased, and I have more power and a smoother running engine. My beloved Mazda has 460,000 on it and runs beautifully. We now use this product, along with the Lucas 15/40 truck oil, in all our vehicles, from the Mazda to the Peterbilt to the farm tractors. Wonderful products!
