Yesterday when I calculated the average using tankful to tankful method, I found that to be lesser than the digital reading as you pointed out. Don't remember exactly by how much, but it was in the 5-10 % range.

MID Average does not account for fuel evaporation due to heat. Also some MID's do not calculate when the engine is idling. Perhaps that explains the variation?

Could ne what you say since my Civic is driver far less than the Brio. But evaporation losses are far less in new cars since the stuff is captured in an adsorbent and then sucked back. Also, I do see the figure dropping esp. when stuck in traffic immediately after filling.

I'm no expert, but I think fuel tanks are still designed to vent out some fuel in order protect the tank from excess pressure. So evaporation is still a factor. Also, from what I have read, Diesel evaporation is less than petrol.
I guess most of the modern MID's do account for idling consumption (My Vento does too).

I checked the recommended pressure for my (petrol) amaze again. It's 29 psi for both front and rear tyres . Am I reading it wrong? Can somebody please confirm? Thanks!

Guess it depends on the car. On my A-star and Optra (petrol), the recommended pressure is the same for all 4 wheels.
But, as Sgiitk pointed out, the Brio needs a higher pressure at front.

I agree, but then, let's not forget that the Amaze is Brio's sibling and the 1.2L i-vtec is the same engine. Hence was surprised at the variation in the recommended tyre pressure. Perhaps Sgiitk can throw some light on this.

Quite likely to be so since their is more weight over the rear tyres.

Thank you! I take it to mean that as compared to the Brio, the extra weight of the Amaze at the rear would balance out that of the engine in the front?

Not exactly, you will not get the 50:50 front to rear ratio but it will become more favourable as compared to the Brio. Only a few Beemers and the Alfa's with rear mounted gearboxes, and of course the exotic mid engined lot are in this regime.

i have a doubt. heard VW Vento ground clearance is not enough and its hitting the speed breakers with 168 mm of GC. How about Amaze with 165 mm Ground Clearance. people who are using please clarify this. I have booked an Amaze - SMT. awaiting your response.

Though not sure if that is the case here, apart from ground clearance wheelbase and over- hang also are major factors.

I personally haven't scraped even once, even with 4 adults on board. Most of the time though, I am alone with my love , so chances of scraping the bottom over speedbrakers, is also low, in all fairness. But I am quite sure it's not an issue as it was with Jazz and Civic.

Just completed a 1000 kms drive over all types of roads - 4 laned roads , 2 laned highways , ghat roads with deep potholes , winding roads ,.. With 5 adults and a boot full of luggage. Never had any issues with scrapping the underbody. FE was about 20.5 kpl overall with AC on 60%. Was sticking to 100-120 kph. Top speed is 145 kph , engine hits a limiter at 145 speedo

Wow 5 adults and boot full luggage, yet no under body scrapping on the ghat sections leading to Mangalore(Those who know these roads will understand) means we can officially certify the GC of the Honda amaze to be excellent even under full load
