Hey guys, Good news to report. Got the car serviced yesterday and got the sump and injectors cleaned, oil changed (to a synthetic Repsol oil - cost alot but worth it), ECU scanned - no issues. Some nuts and bolts tightened here and there. The mechanic said my engine oil was heaps old. He also gave the throttle body a clean. Afterwards, I filled her up with full a tank of BP ultimate and took her for a long long drive today. Looking good so far! I've travelled around 180km, mixed city and highway driving, and only a quarter of the tank is gone. I'll give you guys the final figures once the tank's empty. Btw - my mechanic ranked the fuels (from experience): 1 - BP ultimate 98 2 - Mobil 98 3 - Shell Optimax 4 - Caltex Vortex 98 --> basically, he advised never to use this. Cheers! Dave.
