Swift Diesel fuel efficiency dilemma

ece2k2 · 5th July 2008, 18:15

Hi Guys,

I have a basic question about the fuel efficiency offered by Swift D. I got 14.5 kmpl in pure bangalore city driving (last time I got 15 kmpl in city driving), whereas I got as high as 22 in highways. I am not sure if my interpretation is right as I am seeing a difference of 7 kmpl between highway and city conditions. My brother in law who also owns Swift VDi has never got above 15 kmpl in coimbatore city driving. But I see many of them quoting a city mileage of around 17-18 kmpl. I drive with a light foot upshifting at proper speeds/rpm without a/c most of the time.

I am not sure if a relatively low city fuel efficiency is due to the fact that I drive just 3 km one way, 4 times a day (similar to my bro-in-law). So, it is like driving 3 km every time with the cold engine. Is it true that the fuel efficiency increases considerably if I drive with sufficiently warm engine - like 12 km in a single stretch. Or, if I need to tweak my city driving skills ?

Regards,
Karthik.

karthik:i get 14 to 16 kmpl inside bangalore too, depending on the traffic and AC usage. And yes short sprints do eat up the FE. Would advice you not to break your head over it, maybe check your air pressure for tyres, keeping it at company specs will give better FE and a choppier ride and rattles.

getting 18 in pure city driving with 3km trips is very difficult.
there is usually a lot of fuel wasted parking and reversing.

15 is pretty good for what you described.

Thanks for the quick reply Jaggu Sir! 14.5 kmpl is with N2 inflated tires @ 36/33 psi (front/rear).

Yes, short sprints seems to eat up a lot of fuel in SWIFT D. I didnt see this happening in my earlier petrol cars. Does this factor and difference margin hold good for other diesel cars too ?

rg,
reversing/parking process is pretty much negligible in my case, but i do idle the engine for a min before i stop the car everytime. and i get moving as soon as i start the car.

Yes multijet generally take longer to reach ideal operating temperatures compared to petrol. If i avoid my lunch trips on a regular basis (which is a short run) my FE generally goes up by a km.

Well unless iam doing long trips and very high speeds, i dont idle for more than 10-15 sec, and usually before i park i ensure my rpms drop to 1500 for a few atleast, in driveways and reversing.

There is no need to idle for a minute after stopping. what I do is, I idle the engine during the last 1 min of the drive. as long as you stay below 1800rpm during the last 2-3 mins of the drive, the turbo will not spin very fast, and the residual heat which we are all scared about will not cause trouble.

so instead of idling the engine while stationary and wasting fuel, use the last few minutes to cool off the turbo.

For Bangalore traffic conditions I am also getting around the same 15 -16Kmpl

I think the short distance you have mentioned is not a big issue as I do 15 km one way to office.

Sorry Guys,

A lot of people in the forum are not ready to reveal their correct FE.
something is pretended them to tell lie.
One of my colleague has a Swift Ldi and he told me getting 22 kmpl in Chennai City traffic with 50% AC.he used to travel more than 30kms drive from his home to office in very congested roads of chennai.
But I am surely not rely in his statement.
The moral is,People never give up their loved ones (read as CAR)

NOTE:
I am the one of the person repeatedly telling not get enough FE in GAS.
This is the forum to share the original data/issue and get the feedback from fellow Tbhpians to rid from the problem.
Ok let's see once i get my GetZ Crdi i too join in the group people.
i would tell am getting 15+ kmpl with 100% AC in Chennai City.
who knows the future?

That is why we are revealing the real life figure, 14 to 16 kmpl is good FE in city like Bangalore. AC makes a max diff of 1 kmpl in this if its 0% usage.

21-22 kmpl might be possible for people having great roads and smooth traffic at 60-70 kmph.

meghan · 7th July 2008, 15:36

Even I get around 15 kmpl in the city (Pune) with all drives <5km at a time and AC on 90% of the time. But on highways also, i recently measured it only to be around 17-18kmpl with mixed driving AC on full time at a constant 80-100kmph at times(and using the turbo quite a bit) and below 40kmph on very bad stretches.
Is the highway efficiency not good?

Rocky_Balboa · 7th July 2008, 16:57

I am getting 17-18kpl very consistently within bangalore, with 0% a/c.
It did drop behind 16kpl a couple of times due to spirited driving.

On highways, it is +20 unless I am on the GQ

Within City: 34/32 for tyre pressure and light footed.
On GQ: +1 for tyre pressures, and never light footed.

You guys are cribbing about getting 15 kmpl in city and 22 kmpl on highways?! Misers!

aaggoswami · 7th July 2008, 18:56

This is good fuel efficiency. Much depends upon the traffic conditions and how you are using the throttle.

14-15 kmpl in a city like Bangalore is good to say the least.

Hi Karthik,

You are getting good fule efficiency, bache ke jaan loge kai

Enjoy you car, as everything seems normal about your fuel efficency.
