Brad Bowen uses Lucas Oil Stabilizer in '92 Silverado

I usally don't believe in oil addittives as most people use them as a quick fix. However I have a 92 Silverado that is in perfect shape with the exception of a NASTY lifter tick at cold starts. I haven't had time to replace the lifters so I purchased some of your oil stabilizer. The tick is COMPLETELY gone and my truck idles smoother than it ever has. I am absoulutely impressed with this product. I now use Lucas products for every fluid in my 32,000 mile 2001 CamaroSS. I can't say enough about your product and wanted to let you know it!
