I am Speed Demon and was referred to your club by the Vectra C club. I own a 02 Vectra C Elite "saloon" with a z22se engine. Model level is ELITE and a Saloon model, which i have been told by the Vectra C club is quite rare. The car when i bought it had 155,000 miles on it, as the previous owner visited his family in Poland regularly, so constant high speed driving. It now has 165,000 miles and runs well. I change the oil and filter with Fully-Synthetic evry 6 months, but wonder how long the engine will still last out. Has anyone got any suggestions as to wether is should have any engine work done or leave it alone. Thanks and glad you folks have got a club devoted to the engine.
