Most of the times, I do follow these rules: avoid sudden acceleration/sudden braking, drive sedately. But yes, there are exceptions and those will hamper the FE in city.

But is this drastic difference in FE between city and highway is acceptable? I know few colleagues who drive enthusiastically but still get around 13-14kmpl in city with AC (I agree they have newer cars, and much fuel efficient than mine), that made me wonder if I need to change my driving style or there's some issue with the car.
Don't worry I had the exact same car and problem. I too had a 2005 Santro which I sold in 2008. I used to get 9.5 in city and 12 on highway. I shifted to a 2005 Corolla which gave me 9.5 in city and 14 on highway! I was up in arms with Hyundai for this problem and when they said they will do a mileage test run with all their confidence that nothing was wrong with the car I gave a second thought. I did a very disciplined airport run one day maintaining 60 kms without AC and 70 to 80 kms on the way back and I got 17.67 kms/ltr!

It was my spirited driving style and hyper sensitive to inputs Santro engine, combination of both actually. You have to be extra careful with the throttle and in bad traffic you just cannot do anything.

I never changed my driving style, I just changed my car. Moreover my Corolla gave me 14 on highway when my average speed was 120-140. Also I used to spend more on 2 services in 10k kms (every 5000 kms once service, oil change every 10000 kms) on Santro as compared to 1 service of Corolla, in a year.

Generally smaller engines are more sensitive to driving style and traffic. But MSIL, Honda, Toyota and even Nissan small petrol engines are far better compared to Hyundai for our traffic when it comes to mileage and reliability.

Nissan Sunny xl Diesel 2012 model. Fuel efficiency during a long drive from delhi to palampur (around 550 kms, out of which approx 200 kms was upslope on the mountains) was 19.7 kmpl. AC on 95% of the time. tankful to tankful method. MID average figures were 25.

FE on the way back was 21.9 kmpl. AC on 90% of the time.

You couldn't have encountered upslope for 200kms on this route. Hills only start after Mubarikpur and that's around 100kms away from Palampur. I specifically take this route too because of less hilly terrain compared to other routes.

You are right. However the FE figures stand. ☺

My Honda city ivtec 2010 model is consistently returning me 18kmpl as per MID on light foot and 15kmpl on normal and 12 kmpl on heavy foot. In city, average is 13kmpl and in highway, 17 kmpl.

Dear pkulkarni, our BHPian friend zulfi hansi has hit the nail on its head above. Actually I forgot to mention this point in my earlier post. Smaller engines are very sensitive to driving conditions. There could easily be a difference of 5-6 kmpl between the city and highway FE figures for smaller engines. Bigger engines are more tolerant. In my Innova this difference would be 1-2 kmpl at the max. Many multijet owners (which is a smaller diesel engine) can manage 14-15 kmpl in city driving, but the same cars return up to 20 kmpl or even beyond that on highways.

Re: What is your Actual Fuel Efficiency?

Nissan Sunny XL Diesel (Oct 2012 Model)

Fuel efficiency in City (Delhi) (Tank Top Method) - 15.7 kmpl (100% AC on).

The mileage was over a distance of 300 kms. MID average figures were 18.8. So quite a lot of variation between actual and MID mileage.

Also, i drive mainly in Luytens zone where traffic is relatively less. So, in other more congested city roads the figures may end up lower.

Your best is just around 21 kmpl only? The ARAI rating is at around 25 kmpl, right?

These are all full tank to full tank numbers. Of course, the peak efficiency can be much higher.

I have hit 35KMPL on a mileage marathon over ~20KM or so before I lost my patience.
Bunny Punia hit about 42KMPL going from Bangalore to Pune. So it's definitely capable of achieving the ARAI numbers, if you drive at a constant 55-60KMPH.
If it had a 6th gear, it'd have made it easier to cruise at 80-100KMPH and still hit really amazing figures.

BTW as a reference, lifetime average of my 1st gen Swift diesel with similar usage was ~17KMPL. So I'd say that the Aspire is about 10% more fuel efficient in my hands.

Re: What is your Actual Fuel Efficiency?

Swift Dzire Automatic @50,000 kms -- completely driven in city with AC always on. Fuel topped up at the same bunk and dispenser.
Mileage: 392 (kms driven) / 33.97 (litres required to top up the tank) = 11.53

Re: What is your Actual Fuel Efficiency?

My Vista Quadrajet gives me about 14KMPL in city - With full time A/C.
On the highway, it gives around 18KMPL, when driven in 100kmp/h speed.

Re: What is your Actual Fuel Efficiency?

Our Zest Revotron continues to pleasantly surprise when it comes to fuel efficiency. On a recently concludes weekend trip from Bhilai to Bandhavgarh and back, we did 850 kms of single-carriageway with a mix of good roads, bad roads, no roads and numerous ghat sections. Though I drove sedately for most of the journey, there was some spirited driving in between.

Overall fuel efficiency was 15.3 kpl as per MID. I have earlier tracked the accuracy of MID and found it to be pretty accurate.
