Vandale has over 160,000 miles on a 1999 Nissan Altima and Still Going Strong With Lucas Heavy Duty Stabilizer

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.
