Horst Serschen uses Lucas Synthetic Oil Stabilizer

At 155.000km. I rebuild the 4.3L,.030" over with Competition high performance parts, 10:1 comp.ratio. Now I have 212.000km on the odometer and since three month I was blowing blue smoke on most short time start ups. Over night parking and morning starts are OK no blue smoke. A friend of mine told me about your "OIL STABILIZER". I used half a bottle and two days later I have not noticed any smoke other than normal white in the morning when it was cold, but nor more blue smoke on short distant driving. I was very suprised and happy at the same time that your product is working as per your claim. Most other products do not what they say. Thank you very much and keep up the good work. Horst Serschen
