Just finished a trip on NH-17 and got a mileage of 17-18 with 80% AC usage in my santro.

DZire VDI
22.x highway
15.x banglore city
ac 100%

[harishnayak]

Alto - FFE , K&N , ALLOYS ( 12 inchers ) - 17.5 with 90% AC in city

Spark - HR ALLOYS ( 13 inchers ) - Only 12.5-13 KMPL with 90% AC in city

[jkdas]

Update at 45k;

Anywhere between 10.5-12kmpl with AC depending on driving style. Never lower than 10kmpl ever. Have got 13or so when I was doing run in!

Tata Safari 2.2L EX 4x2 2008 model; stock tyres/alloys.

Since there is no section for fuel efficiency in International car scene, posting here;

Almost 180 miles per 10 US gallon. Equal to 8 kmpl approximate , with AC all the time, mixed on ordinary roads and freeways .

2007 Ford Mustang V6 4L Coupe A/T, completely stock car.

What I did was fill up the tank, note down the litres of petrol going in and drive on till the needle touched the red line, then fill tank again to see how many litres go in. I got a reading of 16.94 for my Alto (100% AC driving on Bombay roads)

Is there any other way of getting a more accurate reading?

Yes there are threads on this issue, but let me elaborate this full-tank to full-tank method once again. Firstly, please do not depend upon the fuel gauge needle to ascertain your amount of fuel, because it is neither sensitive enough nor repeatable. The full-tank to full-tank method relies on a sensor built into the spout of the dispenser at the petrol pump.
This is how that sensor works: When the fuel level in your tank reaches the mouth of the spout the sensor is activated and the fuel can be auto-stopped. This method too has an error depending upon how deep the spout of dispenser is inserted into the tank. However, this error is insignificant, especially because the spout never reaches the tank but remains in the narrow inlet tube of your fuel tank.
So now how do you apply this method?
1. Fill gas up to the auto cutoff level. Does not matter how much fuel went in, but note down the ODO reading (or even reset your trip meter).
2. Drive your car around till you have consumed enough fuel to give a reasonable FE (say 10 to 15 liters, could be more if you like).
3. Again fill up gas to the auto cutoff level (preferably at the same pump) and this time note the quantity of gas that went in to bring up the level. Note down the ODO reading (and note down the trip meter).
4. So now you have both the values: the kilometers run and the amount of gas consumed. From these values you can compute the FE, I guess by using the arithmetic division. QED.
Most T-BHPians maintain continuous logs of their fuel consumption, which gives a running commentary on their FE. This helps as an early warning device for any problems with your car.

The fuel consumption of Skoda Laura 1.8 TSI is not what is claimed by Skoda or its dealers. According to the October issue of OVERDRIVE, this car gave only 7.2 kmpl with the best being 7.9 kmpl! The car was driven 550 km and the fuel used was 76 litres. A Delhi Skoda dealer claimed that it does 9 kmpl in the city and 12 to 13 on the highway!

19.5 kmpl on the highway with ac on 50% of the time.Measured from tank fill to fill. This is a 1.8 litre petrol car.Speed kept below 100kmph for the 250 km trip.
I am loving it.
Any guesses???
My signature and avtar would give away

That has to be a good FE for the 1.8 from Toyota i guess. I would have thought 0.8 from a different car maker, if not for that 1.8 Hint.

I have clocked 80000+ kms in my Santro in last 3.5 years, 90% on highway, with 100% AC on, I usually gets 17 to 18 kmpl (full tank to full tank method), while in city around 12.5 kmpl.

[karpusv]

Have my Logan 1.5DCi now for 2 yrs, run 22000 kms+

Have been getting consistent Avg of 18~18.5 in city and 23~26 in highways (both cases A/C On for 80% times)

12.5 kmpl is less isn't it? My friends santro gives hi 15 kmpl in Delhi with 100% AC on

A friend of mine gets 17 with ac in Delhi from his santro. It's the driving.

I have got 17+ from my wagonR as well, when I drove in some super economy mode. Last I got from my wagonR (today) is 9.5km/l. . . imagine the driving.

I totally agree with you however i'm facing a major problem with my Spark. It gives me max 14 in IDEAL driving conditions - I'm really fed up. Maybe because of the HR alloys installed by me.

I'm done trying to drive conservatively with a sane mind in the horrendous traffic in BLR.now with occasional spirited (no connection to alcohol LOL) driving in my puny lil alto with 50% AC i get 17.5.
I'm satisfied and am not trying hard to get that FE. this is a consistent number as long as I fuel up at IOC. Shell fuel gives me 17 with the same kinda driving.
