Brad Kasl uses Lucas Heavy Duty Oil Stabilizer for Dodge Dakota


Just wanted to write and tell you how happy I’ve been with your products. I’m one of those guys who buys “older” trucks, nothing less than 100,000 miles in my garage since I started driving. I also switch them out about once a year. With that comes a complete fluid change on each on each one of them. I’ve been using your engine oil additive for about two years now. I had a Dodge Dakota with 150,000 miles on a 3.9 V-6 and man was it a noise maker. I started using your oil additive and within 2,000 miles it was much more quiet. It seemed to help it run cooler also. I now have a 1991 Dodge D-150 with similar miles, it has been treated and seems to be much smoother and appears to be gaining some oil pressure back. The tranny had a couple of leaks around the pan, so I added some of your Trans fluid and again within a couple thousand miles it was healed up. The differential was pretty noisy going down the road, I pulled the cover and the fluid ran out thinner than water. I cleaned it up and put in some 90 weight and a bottle of your oil treatment, it’s very quiet now. It’s nice to see folks putting out a good product that does what it is said to do. Being a race fan I also appreciate what you are doing to help out Junie Donlavey and Lance Hooper at Bristol. If you could send me a catalog so I could order a couple of decals, I’d really appreciate it.

Keep Smilin'
