am happy to say that there has been a massive improvement in my consumption. this is how i did it.....i changed the fan module cos i noticed the fans were not working up to their capacity and interestingly my a/c issue too has been solved, no more sweat when in traffic.. then i pumped up my tyres a little bit and with the injector cleaner i used over the weekend, i have for the first time recorded 24MPG city and this is incredible considering the traffic i stayed in for nearly 45mins. Many thanks to everyone who contributed to this success
