Just want to rant a bit on the fuel consumption!
So, my Bezza Advance is 1 year old (1 year 1 months to be exact, about 15000 KM).
Bezza advertised to have 22 KM/L, so I expect to get 15-16 KM/L in real life, but from day 1 until my 2nd service on yesterday, I got around 13.5 KM/L, fine, I was always stuck in traffic jam for my journey from Cheras to PJ during peak hour, although I felt a bit unsatisfied with that level of fuel consumption, but I don't really complaint.
Then on yesterday, I went for the 2nd service, the service centre recommend for alignment and nitrogen, claiming will get better fuel consumption, so I agreed to it, since the price is quite reasonable. After the service, I reset the average fuel consumption meter, and has been driving around highway and housing area road on weekend, really no jam at all since it's weekend, and guess what? my average fuel consumption is 9.5 - 10 KM/L, that is even worse than my 16 years old Proton Saga (auto)!!!!
I don't keep heavy objects in my car, I only keep 1 pair of safety boot, I drive alone 90% of the time (I'm about 75kg), always keeping the tyre at the recommended 36 bar, and I don't drive harshly (ok, maybe 5% of the time), yet still get such a low level of fuel efficiency
