Little (or no) difference between petrol brands in Malaysia in terms of fuel consumption (after 1.5 years of measurements)

This blog entry is an update to my first report on my car’s fuel consumption (FC) for various petrol brands.
Background of study
About one and a half years ago, I started to measure the fuel consumption (FC) for my new car (Nissan Grand Livina). Like any new car owner, I was curious about my car’s FC. I then decided to determine if there was any difference in FC between petrol brands in Malaysia. After six months of measurements, I reported my results here in my blog (Read here).
I reported then that there was a difference between petrol brands, notably between Shell and Petronas. I discovered that Shell gave the lowest FC for city driving but Petronas the lowest for highway driving. My results then was surprising because I had always presumed that even if there was any difference between petrol brands, their differences would be too small to be appreciated or noticeable in normal driving conditions.

Which petrol brand in Malaysia gives the lowest fuel consumption? BHP, Esso, Petronas, or Shell? (photo from santainrileks.wordpress.com)
I continued with my measurements because I wondered if my initial findings would remain stable over prolonged time (in other words, was my initial results due to chance?).
