SX4 low mileage :(

memo45_m · 24th September 2007, 06:41

Well as everyone knows the the first batch of sx4 were called in for a clutch replacement, and there is also a problem with the AC which works too hard if you have the car in the climate control mode, which is the main culprit too for low milage.. the ac thing is still being sorted out by maruthi and the dealers,

....

last week i had given it to the service station citing the same fault (kapico motors) got it back but the problem still persists ..

i just wanted to find out what could be the possible reason for the abysmally low mileage .. done around 1300 kms and the whole thingy in the city itself ..

well just ask your service guys to connect the techIII and ask them to see if all the parameters are set right or is there any flashing of error codes(by the way for those who are trying to plug the sx4 with the techII it will not work as the communications mode on the sx4 obd2 is different from all other maruthi's).

itz hovering around 9.5 now !

Thanx a lot guys for being really patient .. team-bhp rox

and the tank-2-tank method is only for the measure right ? so i guess there is some fault with the car itself ..

IMHO, "emptying the fuel tank" may not be a good method to find out FE. The quantum of fuel left in the tank when the car completely comes to a stop is not the same each time you run the car to a complete stop!!! Plus, checking mileage with 3 liters of fuel itself has a lot of variance in the process.

Anyway, good to hear that with the full tank method you are getting >9kmpl.

Best way to find/report FE: Total distance travelled (Odo reading) / total fuel used to travel that distance. This would be the overall FE over time.

Also, full tank fuel also helps wash the walls of the fuel tank, top to bottom.

Cheers.

I am surprised that you guys mention the mileage of sx4 as 8-9.all the cars i have seen is returning arround 12-13 and i know a guy who had a city which was givingg him 17 and thenn he got his sx4 which is giving him arround 14 -15 regularly with a/c.these figures are tank full to tank full.

Venkatesh.C · 10th November 2007, 20:11

Hey @13g014s, first read up some of the other forums for tips to measure FE. Tank full to Tankfull in short is the way to do it. I guess your measurement is flawed (sorry if it sounds harsh.but thats the truth). I'm sure you may be getting more than 8.
Check out the SX4 threads elsewhere in long term ownership sections. Everyone gets 9 + in the city. Some even claim 11.
I get 9.5 in the city and 14.5 in the highways.
I strongly suggest you measure your FE correctly (again time to read up) and if its still not in the 9+ region then you take your car to a different service station and get some help.
I get 9.5 in the city (AC on always.B2B traffic only). 14.5 in the highways.

Yes , as ya pointed out my method is probably flawed .. Might sound funny but to test the "real" mileage , always used to carry 3 litres of petrol whenever i reached the E-mark ! Allowed it go empty .. calculate the fuel consumption , open the boot .. fill those 3 litres and used to the rush to the closest pump ! (Stopped doing it these days ! but do i risk engine damage by allowing it to run till empty tank ??)

And yea from now onwards will go for the tank-2-tank method .. Will update ya guys on the mileage this way .. I just hope the mileage of my car is on par with the other folks here at team-bhp !

Well my method of calculation could be wrong actually ! i fill in , say 20 litres , allow it finish (bottles in the car ya see

) and then calculate the mileage ! As other members have pointed out , i shall use the tank2tank method . I guess my car will return a higher mileage that way ..

Hi l3g0l4s,

One of my friends works at the Maruti showroom. He said people comfortably achieve 10kmpl.

This makes me wonder (after Swift petrol, now SX4) why Maruti cars are no longer the economical types.

Good luck with resolving your issues.

DineshKanna · 12th November 2007, 12:53

Hi,

Initially i use to get 10.4 Kmpl in city and 14.5 Kmpl in Highway with a/c. Now i have done 4300 Kms and in city FE raised by 1 km which is 11.4 Kmpl. I always use the auto option for the a/c. My sx4 did not fall under the clutch replacement batch. I guess thru good driving habit we could still increase the FE of this vehicle. And during the initial 1000 Km the gear shift was hard but now its better.

Thanx mate

Anyways i just feel that my method of calculation is flawed ! Will calculate the FE with tank2tank method and then post the mileage

drpullockaran · 12th November 2007, 23:15

You might think it to be impossible but I do know a few cars from various manufacturers where the mileage went down drastically after the first service because of the following reasons.
1. Improper wheel alignment.
2. Swapping out of a perfectly normal Oxygen sensor with a faulty one from another car known to the mechanic.
3. Swapping out of a perfectly normal ECU with a faulty one from another car known to the mechanic.

The last two reasons are the most plausible ones for such a drastic change in your fuel efficiency.
Since these days the ECU in new maruti cars are not easily swappable its mostly likely the lambda sensor thats been swapped. The least possible reason is that your pump attender found an ingenious way to put less fuel in your car. It is advised that you mark all your major swappable components with a small dot of nail polish. Nail polish paint does not come off so easily.

Bye and wear your seat belts.

Guyz i need help !
My SX4 which is a june-july 2007 model (13 k on the odo) gives very low FE. And this is despite the fact that i make it a point to fill up from a BP-company owned petrol pump near my house and my car is in terrific performance state. Every time i fill up, it refuses to return above a fixed 7.98 kmpl, whatever may be my driving style, road conditions etc. These are 100% AC figures and i tend to drive normally and not very rash. I faced a few problems earlier :

1. The car's rpm started dropping by the day and one fine day it started stalling completely if i depressed the clutch or while at idle. The M.A.S.S "reported" it as bad fuel and rectified it. A few days later the problem emerged again, and this time the wise-guyz reprogrammed the ECU. Amazingly, the car was fine again.
2. Some days later I noticed that the A.C was putting too much of a load on the engine, and that it caused the revs to fall down and remain low, leading to a not-so-smooth idle and harsh engine while driving. Gave it to RanaMotors, Okhla (by far the best M.A.S.S) and they fixed it up very neatly (some sensor near the injectors, which controls the rpm). Everything restored to normal.
3. Ever since the sensor problem has been rectified, the new car is altogether a different machine. The pick-up is super even at low-revs, the car's engine note is super smooth and the overall performance has improved by miles. The only thing though, i feel the FE has gone down a bit more..its still returning 7.5-8 kmpl, w/o failure.

I can't figure out the problem, because the performance is like at an alltime high..so i d;nt feel there's a problem with the engine or something. Can it be due to the sensor not repaired properly ?? Can it be the Oxygen sensor ?
I'm really worried..because Rs.6/km makes me go mad !
Help !

P.S Sx4 owners kindly mention what FE you guyz are getting and in what conditons, how much do you drive in a day etc.

HI

Try re-setting the ECU, by unplugging the negitive battery cable for few mins. Might work!!!!
