My Alza Fuel Consumption Averages at 12.6km/l
Kew 
My Alza Fuel Consumption inches up to 12.6km/l from previous update of 12.5km/l. There are virtually no change to the fuel consumption average. The Fuel consumption average that I plot on the graph as a red line is the average fuel consumption since day 1. Since the last update, I had 7 pumps and had travelled over 3000 km. The best Fuel Consumption performance was 17km/l with Shell Ron95 travelling on the Highway. The worst was 10.4km/l with Caltex Ron95 city travelling. In the last few fill, I have not been paying attention to the fuel consumption. In addition, there were a list of problems with the car which I believe have a bit to do with the poor fuel efficiency of the car.
During the 10k service, I complaint about Squeaking sound that the Perodua Service Center note to be due to Air Condition problem and electrical problem. I also ask them to rotate the tyre and perform balancing. Right after that, I went onto the Hwy and found that at high speed 110km/h, the steering vibrates. I went back to Perodua Service Center and they said that this is because the balancing that they did were for low speed and they do not do high speed balancing. Nevertheless, they re-look into the problem and it still persist. The electrical problem causes the car meter to go off and on again during idling. In addition, the A/T indicator were on much longer than usual. The service center found the problem to be due to Battery and they changed a new battery for me. The Air Condition problem were not fix as the service center said they are ringing in the air condition for warranty.
For Mobil and Caltex, this is only one data point and I plan to take at least 30 data point to compare with the usual Shell Ron 95 that I use. Therefore, it is too early to make any conclusion. Many MyAlza forumers have reported better performance with BHP, Caltex Techron and Petronas, so I do expect to see a better performance with the mention brands.
