Since my first oil change on my 92 Kenworth after buying it used with 200,000 miles on it .The previous owner only used LUCAS OIL. It now has 650,000 miles and still no oil useage. I would not use anything but LUCAS. My racing miata now uses only 20 / 50 synthetic MOTOR OIL . The oil survived 2 hours of practice and a 4 hour induro and when drained still looked like new . This year I will put it to the ultimate test a 25 hour enduro at THUNDER HILL RACEWAY .This will be a brutal test wich I would not attemt with out LUCAS Oil Thanks....

Just a quick note to tell you how much I like a couple of your products. I have never been one that believed in these tuneup in a can products but after trying a couple of your products I was quite impressed. I have an old 96 kenworth with over 1000000 miles on it and noticed that the power steering pump was making a whinning noise and had a couple of hard spots where it would lock up for a moment. I was 3 days from home so decided to add a jug of Lucas power steering treatment and kept my fingers crossed that I could get home before the pump packed up entirely. The noise disappeared and now steers easier than it did when new! That was 6 weeks ago and still is working great. I then decided to try Lucas oil stabilizer in the engine and was equally impressed with how it seemed to smooth out and quiet down the engine. I am sure it is getting close to rebuild time but hopefully now I can go a bit longer before having that cost. Thanks!

Hello, my name is Mike Waters and I work for Kenworth. I must say that, with much hesitation did use yourproduct. However I wish that I would have been using it much, much sooner. I used your product after hearing much about it from drivers and fleet owners, whom I thought were only imagining a difference after using Lucas. I must say that I now useLucas in everything I own that has a resevoir.

I am a lady truck driver who has driven consistently for about 10 years. I became an owner operator in 1996. I bought my 1993 KW T-600B, with Detroit series 60 engine in 1996, used, with 410,000 miles on it. It had been run hard and I had no idea what the maintenance had been prior to my purchase (it's an old Prime, Inc vehicle). I had used Lucas Fuel Additive previously in company trucks and knew it increased fuel mileage. So when I bought my KW I wanted to give myself a fair chance at success by giving it the best. I have used Lucas Fuel Additive with an increase of 0.5 mpg and for its benefit as an upper cylinder lube. I also use Lucas Oil Stabilizer treatment, 3 gals to the service since I bought the truck, until it reached 1 million miles, then I put 4 gals to the oil at changing. Now I have 1,100,000 miles on my truck and she is still going strong! No smoking and it still uses the gal oil a week it always did. Did I mention that I also use Lucas 5th Wheel Lube? I do and I am more than satisfied with its ease of application and smoother trailer movement. Thanks Lucas keep up the good work.

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.

I am writing in reference to your engine oil additive, at work we use your additive in our bucket trucks, dozers and other heavy equipment without incident. I decided to take some home and try it in my racecar. My engine oil is changed regularly after three races. Lucas oil additive was added and my oil pressure increased 5 pounds. I use Pennzoil 25-50 and run methanol. Everyone well knows that condensation builds up in the oil pan with alcohol especially in cold weather. Last season after adding Lucas oil additive to the engine, we tore the front bumper off and it went under the car and burst the oil pan. During that time, I was trying to get my drivers attention, he had made three laps with the oil pouring out. Needless to say, by the time it was shut down I was expecting some serious bearing damage. After getting the car to the shop and pulling the pan to check rods and mains, expecting the worst, there was no damage. Boy was I tickled LOL!!!!!!! Since that time, I have always added your product. We have raced 48 races this year in the U.M.P. modified series and used the same engine every race and have not torn it down for nothing. The engine still has 55 to 60 pounds at idle and 50 after the race is complete. Our engine is currently at the shop to be freshened for next season, cannot wait to see what bearings look like after 2,000 laps of racing on dirt.

I am a faithful Lucas Oil customer and have been for several years. I own a Class 8 truck with a Detroit Series 60 engine. My oil samples come back with comments about how well the oil has withstood the miles on that sample.

Last week my auto parts supplier, Burt Thomason of Owens Cross Roads Alabama, talked to me into trying your product for my 2002 chevy blazer. I was surprised at the difference. My real story is my 1939 Ford 9n tractor that had a very bad noise in the finial drive. I had inspected this about a year ago and knew that a ring gear needed replacing. This is a show tractor and was the last tractor my dad had owned before his death.

I am the owner of a small earth removal and transporting company in Southern Michigan. My company currently has in service, 6 gravel trains, 3 pans, 2 loaders, 4 dozers, and 2 service trucks. Last year I ran into a problem with one of our service trucks. The power steering pump was leaking and whistling like a bird. Our friends at Schwallbach's Auto told us about your LUCAS Power Steering Stop Leak that they buy it and use it in their racecar. When my workers went to put the fluid in, they realized that we had run the pump bone-dry. They filled up the pump with fluid and started the truck. It was still singing and dripping as before. While running, they dumped some of your Power Steering Stop Leak in and the whistling ended immediately as well as the leak. I was sold. I have since used many other products from LUCAS and the result has always been excellent. This winter, during our servicing time, I had every truck and equipment switched over to your products. You guys produce a grade-A product and I thank you for helping to keep my guys on the road.

I am an owner operator of a 94 IHC. 425 C CAT. I use your products in diffs transmission and engine all the time. I would just like to congratulate you on one of the best products I have ever used. I am also a licensed heavy-duty diesel mechanic so I have tried them all looking for one that does what they say. Yours is that product. I have made a believer out of my boss and he now uses your Oil Stabilizer in his 11 company trucks. Once again, thank you and I will continue to use your Lucas Products!
