I waited. After 3,000 miles and no improvement, I stopped at an autoparts store and bought a quart of fuel additive. The engine started to run smoother. 100 miles later, no smoke, the engine runs smoothly, it no longer downshifts going up even steep grades. I now get at least 42 MPG and the car is wonderful.

I justed wanted to say thanks for manufacturing great products that we depend on week in and week out. I put my little Vega through a torture test this weekend locally. I entered three classes (Super Pro, Pro (No Box) and Footbrake) at I-57 Dragstrip Saturday, then Super Pro and No Box at Cars For Kids Accelaquarter Raceway Park on Sunday. In the two days, I went down the track 39 times and never raised the hood. While they weren't big events, the results were fantastic: 3 wins, 1 runner-up, 1 semi-final. 30-2 round record on the weekend! Everything worked flawlessly, as I've come to expect.

Just wanted to write and say thank you for making products that actually do what they say they will. I bought an old (1996 Dodge Ram) with 160,000 miles on it. The first week I had it, the oil pressure would drop to zero at idle and the light would come on. I thought I was in for some big money right away. A friend of mine that is a mechanic said to change the oil and use two quarts of lucas heavy oil stabilizer. I thought it was worth a try since he is a very trustworthy source. Guess what, The guage sets on 20 psi at a stoplight with AC running and on 40 psi when driving at normal speeds.

I just wanted you to know your Lucas Oil Treatment is the best. I had been using it in my girlfriends 2000 Daewoo Nubira. The car had been overheating and finally blew the head gasket. She had driven it a couple of days before letting me know it was having trouble. I drained everything and replaced the head. I pulled the pan to visually check the components. Not a scratch. The car has been running trouble free since. Even though I was told by multiple shops that the motor would not last 1-2 months, this was 8 months ago.

I had a slipping in 1st gear to 2nd gear it was barely moving then i added lucas tranny oil and in about 1hr of driving it fixed the problem and drives great no more slipping for now going to get flush and fill and add another bottle great stuff!!!!

I have used a couple of Lucas products in the past but never something that has worked so incredible, saw the ad on TV and not a big fan of gas additives but decided to purchase Lucas Fuel Injector treatment. My Audi TT was like a new car again after driving about 125 miles it really perked up!

To whom it may concern. I use you Lucas Oil Fuel Treatment product on my 2001 Toyota Tacoma 3.4l V6 every time I fill up. I see an average of 4-5 extra miles per gallon improvement over not using it. I have also used it in my 2006 Porsche Boxster S at every fill up. I love your product and the price is awesome.

Just wanted to say that your gas treatment works great. Gained 4 miles to the gallon. Runs really great. No more stumbling. Glad to see somthing actully work and the price ws great.

I use Lucas Products in all my bikes. But, I want to tell you about my shop truck. In 2006 I bought a S10 pickup for the shop and to pick up bikes. It had 80,000 miles on it, 2.2l with a 5 speed. Shifting wasn't crisp and 3rd gear howled badly. Replaced transmission oil and still had noise. I replaced fluid again but this time added 50% with Lucas Sythetic Stabilizer. About a week later was driving around and noticed shifting felt crisp and could actually feel detents like a new truck and noise was somewhat quieter. A month later noise was gone. 5 years later and 70,000 more miles it still feels great and still quiet. Thanks Lucas.
