the differences in FC were a bit ridiculous to me. But doing standard maintenance actually helped boost my FC by a lot compared to when I first posted. average fc is now around 260km/RM50(half tankish) in the tank with 80% city 20% highway driving so about 520km/tank if i double it.Because of fuel dilution in your engine oil. So yes your experience is consistent.
Change your engine oil more frequent. But don’t expect significantly better FC based on your usage.
