Problem with a VAUXHALL ASTRA G 1.6 8v 2000 90k

Excessive hydrocarbon emissions at 300 ppm, excessive blue smoke and misfire. Suspect fault due to sticking valves and oil burning.

The fault was cured by using Forté Clean & Protect, extended Forté Advanced Formula Motor Flush carried out adding Forté Oil System Protector to the new oil and Forté Advanced Formula Gas Treatment to the fuel tank. The vehicle was then given a 20 mile road test, the misfire and smoking had stopped and the emissions were rechecked showing the hydrocarbons at 20 ppm. The owner also reported a week later that the vehicle had never driven so well.
