My doubt is based on my experience with vintage bikes, I once had a problem where I experienced a shudder when releasing the clutch due to a retarded timing.

What i meant was timing would/should be checked as part of engine tune up. That is basic step.

Gonna head to a mechanic I know on Saturday and get the following checked: (If I have missed anything out, please do lemme know)
Carb overhaul - With a new carb kit (jets, packing/gaskets etc)
Ignition check up - Spark plugs, timing
New air filter
Health of the cat con
Oil change
Clutch health

Thanks, Will try this out!

True that, but I somehow don't trust the work that was done by Chamunda Motors, MASS - Borivali, Mumbai (maybe its my inexperience with 4 wheelers that's talking). The car seemed the same to me, before and after the servicing. Wonder if anyone on the forum has had a good/bed experience there.

This is something I believed as well, untill I read that some folks on the forum are getting much higher FE from their Esteems. Should I take the figures posted with a pinch of salt?

You might get 11 - 12 without AC if you play with the carb AFR settings (smaller jets, play with idle mixture screw). Also the MPFi esteems give slightly better mileage than the 8V carb esteems so some of the figures quoted can be of the MPFI esteems. On the highway you can get around 14-16 depending on what speeds/rpms you drive.

I'd suggest don't worry so much about FE, give it a good tune up and enjoy the car

I used to own a carburetor esteem. Its very easy to change the spark timing, all you have to do is slacken two small bolts. From my experience the car used to drive well with a little retarded timing than what the mechanics used to set with their timing light for petrol and little advanced timing for running on LPG. Also a probable reason for low mileage could be a stuck centrifugal advance or leak in the vacuum advance.

Hello Team,
I own a July 2010 Hyundai i20 CRDi Sportz.
On average I get 16 KmpL. Being high way or in city with 100% A/C.
Mileage is going down compare to last few fills.

Need your expert advice on how the mileage can be improved.
Let me know if you need any information. Thanks all !!!

Below is the tracker for information.

My recently acquired Linea MJD is returning around 10-11 KMPL, I am a tad disappointed as everybody that I know who owns a car with the same engine get upwards of 15 KMPL atleast.

My car has done 1500 kms till date and the service advisor says that will get 15+ post first service.

My previously owned Swift VXI returned similar FE which went up marginally after service.

Can it really increase by 40%-50% after servicing??

I admit that I have not driven a diesel car before, a mere 4 yrs with the Swift and loved it.

Can some one pls suggest

Regards

Suvrajit - is your car driven in the right RPM band (1600 to 2200 RPM). Please try it out and see the difference.

You are driving a diesel for the first time. Thats the difference. In diesels you need to use the torque more. Over revving the engine is not going to help much. There are threads on this forum as how to get maximum out of a diesel.

Do not expect a quantum leap in FE after the servicing.

Thanks Dieselfan, I have taken your advice on running in a diesel engine quite seriously and trying to keep her at that 1600-2200 rev band, while trying to do this in city traffic conditions, I at times feel that the engine is over revved.

I am at a total loss ....

Thanks, you think that you have the link to that handy as I am unable to find any?

Thanks to the FE figures of the recently acquired italian beauty, I have finally become a proud "Bhpian" albeit after 4 years of entering the scene...

Team BHP simply rocks when it comes to the quality of knowledge of the automotive world, even otherwise, I used a link from shifting gears on BSNL landline and got my self one ordered from web without ever visiting them at all!!!

Dieselfan,

While trying to keep to the RPM range of 1600 -2200 I often end up driving only in 2nd or third gear in the normal city driving conditions in namma bengaluru, this should be impacting mileage possibly. I clock around 2.2K RPM to hit 40 on 2nd and upshift. Upshifting any sooner let the tach fall below 1.5 and i start getting worried of lugging.

I drove my Swift in a constant rpm of 1500 -1800 and got around 10-11 KMPL.

Need expert advice on how to transition this change effectively!

@Suvrajit: Personally i would not worry about lugging at 1.5k rpm. 1.5 is not exactly the healthiest rpm, but should be good enought to have decent pickup.

Also, mileage will depend heavily on the kind of roads you drive. I used to stay around old Bangalore and used to get arund 14kmpl (without AC) while now living in a slightly farther area with better roads and i get 16kmpl or 17kmpl also sometimes(again without much usage of AC - with Indica Diesel).
So, roads and traffic, make a big impact.

@deep bang, thanks, yes I live around old bangalore, Banashankari to be precise.

Exactly my thought, AFAIK there is no way to expect a decent FE driving mostly on 2nd and 3rd gear.

I hope that the service guys to manage to do some magic and the goverment with the roads to improve things further!
