I am guessing that you should alter your driving style a bit for diesel. Use the massive torque Verna generates, You need to upshift late and down shift early. Always try to be in the torque band. This should definitely improve mileage.

Was your previous car a petrol car ?

Additionally the differences as Cruiser 1982 has said that you need to use the rev band and not lug the engine like a petrol engine.

If you do lug, avoid it, as it unnecessarily puts stress on engine components.

I have a Petrol and Diesel for many years now and I guess I can adapt well to both driving styles. The diesel I had earlier was an Indigo.

[dinu2506]

No luck yet. My second free service is done, the odometer is at 6300km, the FE is still around 11.5km/lit. The driving has been in City at off peak times but 100% AC. No bumper to bumper traffic. The service centre says everything is normal and its just the driving style which is not something I can fully digest. There has to be some reason for the low FE. My Civic returns 10.5 to 11 on the same routes and my earlier Indigo used to return 14-15.
Can you provide some pointers. My DTE reading shows around 560 to 570 km when I tank up. Should I try and do a ECU reset again? I had tried once long back when the car was nearly new.

[dinu2506]

OK, here's an observation. I tanked up today from HP (to the brim) and came back home - 10km drive. I planned to do the ECU reset today. I checked the DTE (Distance to Empty) and it was showing just 485km which probably means its running an aggressive or uneconomical map. I did the reset by disconnecting the battery and now the DTE shows 596km. I hope it has loaded a conservative map now. Will do the next tankful and update all.
All, any comments on this behavior? How does the DTE work? The fuel quantity is same, so it must be assuming a low FE from the loaded map to calculate the FE.

[dinu2506]

No luck still, the FE has dropped to below 11 in the last 2 tankfuls with a really conservatve driving.

Its too early, but I have a vague feeling that I have found the culprit. I will update you after the next tankful. The indications seem to be very positive by the way the fuel indicator and DTE is behaving, but I'll reserve the verdict when I get the next tankful done. Any guesses?

Here's how the reading are:
Last tankful: Tripmeter:0km DTE reading 530km
Tripmeter: 40km; DTE: 490km
Tripmeter: 60km; DTE: 480km (slight improvement)
Tripmeter: 120km; DTE: 443km (improvement)
Tripmeter: 133 km; DTE: 456km (reversal of trend

Hoping to continue this.

Mine goes from gurgaon to vasant vihar everyday and back. KPL given is 16+, a/c is always on.

Have you tried highway runs? How much does it give on full highways runs.

Also have you tried changing the fuel pump.

[dinu2506]

The highway runs used to return just 15km/lit with a light foot. Definitely not good.

I'm seeing this positive trend just from this tankful. Of course I have done something which probably is working from the way the DTE is moving. I'll let it out ater I get a confirmed FE value after the next tankful. Till then, let the suspense remain

Note from Mod : Old thread that has been bumped up. We have several other Verna ownership discussions that indicate realistic fuel efficiency numbers. Thread closed.
