MPV will only save fuel if u know to drive it correctly
LIke my case i have 2 driver driving the same car (avanza auto 1.3)
if i drive
full tank is abt 450-500km for 40L
if another driver sure stuck at 350-400km only

I know my car is underpower so i nvr push it hard i take my time to accelerate slowly and maintain stable speed

compare to another driver who drive it like sedan style and always accelerate and slow down ==!
