Dear Lucus,
I change my oil every 5,000 miles with synthetic oil and a bottle of Lucas Heavy Duty Oil Stabilizer; and have been doing so for the last 7 years. The other day I pulled into the gas station and filled up my tank, and routinely checked my fluids when I noticed that my engine did not have a drop of oil! I quickly went in purchased (2) quarts of oil and drove home to get my Lucas! I added the Lucas and started the engine and my engine is still running without any problems and I know it was all those years that I had been using your product. I thank God for Lucus and all its products.
