Time at which you travel does matter.
I first got 15.x when I used to leave home at 9AM and leave office at 6:30 PM(bannerghatta road, need to take a U turn near Spar/Auto One . People who are familiar with this road can understand)
Once airport is shifted, and changed my timings ( Leave before 9 and donot leave office between 6 and 8) my FE shot upto 16.5+

FE depends allot on quality of fuel, traffic conditions,roads and most importantly your driving style.

I have been getting FE of a little over 20 in my last 3 fills(No highway runs for my car yet). Following are the things which might be responsible for these figures:

• Filling from Company owened pump, i have filled only once from a non company owned pump and I got a FE of 17 then. Please note that as I have stuck to company owned pump, I have also been forced to use premium diesel. But since I am getting good FE, I have not switched to any other pump.
• Most of my travel is on Ring Road and DND expressway. For those who dont know, the stretch of ring road I travel on(Dhaula Kuan -Ashram) which is about 10 Kms is completely signal free. Add to it the 7Km empty stretch on DND.
• I reach office by 8:30 am , so i have to tackle minimum traffic.
• I have just completed the run-in period of my car, and the car has been taken above 2K RPM on very less occasions. I generally upshift on 2K except 5th Gear which is around 1.6-1.7k.
• AC is on 80-90%, I dont think AC usage under my driving conditions will affect the FE figures hugely.

My 2 Cents.

P.S-I have also upsized my tyres to Michelin MXV8 195/60/R15, and am maintaining tyre pressure of 32(front) and 30 (Rear) on Jaggu and Busa's advice.

As mentioned, a lot also depends on the fuel station that you use for fuelling requirements. As diesel is widely used for commercial usage i.e. trucks/ lorries. Most of the time the diesel is more adulterated as the truck engines are not as sophisticated as DDis or other CRDI engines. So they can take the abuse.
It is a must to switch fuel station at times and practically see the difference - for better or for worse.

I've been using an Android App called "aCar - Car Management, Mileage"
Can be found at Google Play

Found it to be useful as it calculates FE more efficiently and also helpful when it comes to track data of your cars such as Service, Accessories, Service Center details, Service reminders etc.
One can generate reports on monthly / yearly basis per car.

Note: The free version backs up your data once every month, and the full version has a lot more features. I'm on the free version and am good with it.

Thanks

I own a 2013 Dec model Swift ZDi with stock setup fully.

My driving is 108 kms a day with a mix of 40% city and 60 % highway. I am getting an average mileage of 19 kmpl in city and ~ 23 kmpl in highways with 50% A/C (Now it is 100% A/C since the temperatures are 39-41 deg C).

I am on MRF ZVTV tyres - 185/65 R15 with tyre pressures:

F - 33 psi
R - 31 psi

I up shift at 2000 rpm sharp in all gears and down shift just below 1500 rpm as I hate lugging the engine and clutch riding.

My swift VDI 2012,

100% city driving with a/c. This Setting is constant.


Most of the time, my braking is through gears. I hardly go to fourth.
I don’t keep note of tire pressure .
