Default Low Fuel Average... Palio 1.2 ELX!

Hi Guys,

Offlate my palio has been giving me very low fuel average. I changed
timing belt and some bearing alongwith it during my previous service.
I am getting around 8.5 kmpl with careful driving... that touching 70-
80 at times but mostly 50-60 kmph on relatively empty roads,
previously it used to give me atleast 10 kmpl no matter what. Is there
something wrong with the timing belt that i just replaced? What could
be the cause? Its really burning a hole in my pocket coz i drive 60-70
kms daily.

Timing belt is changed as u said but maybe the timing has changed and needs to be adjusted as u said after changing the timing belt you are getting low mileage.Go to the dealer and complain about the low mileage after the changes.He will give u a proper diagnosis.

Also try a different petrol station and brand.. there could be a slight possibility that your regular guy has started some adulteration..

No i fill in from reputed pumps only. Is there any possibility that the service guy has messed up while putting the new timing belt.
How do i check if timing belt has been installed correctly or not?

The timing can only checked with the right gadgets at teh service station.. But, if the timing has been changed, you would surelyy feel some difference in the way teh car is driving..

hi,,
how much has ur car done on the odometer,,
if it has crossed 75,000. then u require a timing belt change in a fiat palio,,
but the way u r driving it,, i think u should get around 10 easily,,
other than that i tried HKS iridium spark plugs in a friends palio the fuel econamy rose by around 15% roughly!!!!!
though this not the solution for ur immediate problem,, u can try this later,,
all the service guy has to do is connect the high scan device and check the timing and adjust it accordingly,,
regards,,

Dammm the scanner device at Samyak motors in Patparganj wasnt working. The engine struggles to move up an incline with the AC on... the if i depress the accelerator a little the revs arent constant, but if i press it further the revs are constant.
Will show the car to the service next weekend. For the time being i'll use my office cab.

All these years we were told that the Palio 1.2 gives a mileage of 8 kmpl but now you say the car used to regularly give a mileage of 10kmpl! I really don't know where the low mileage rumors started though I first read about this in Overdrive. Anyway, about your car, you said it's struggling to go uphill so I am guessing something wasn't done correctly when your car was given for service and the timing belt chain. The best bet is to hook it up to the scanner, i guess. Why don't you get the fuel injectors cleaned and de-carbonize the engine while you are at it? But do let us know what the problem was and how it was solved.

Hi,

A similar situation here with me. I had to change it due to a worn out tensioner bearing (26/7 effect)

I think the problem can be solved after resetting the ECU.

Hey,

The ECU would have got reset by default since any responsible mechanic would disconnect the battery before opening the timing belt/chain. The timing itself cannot be adjusted merely be reseting the ECM it will have to be done manually.

@ Extreme - If the car timing is not set correctly it will not idle properly and pickup also will obviously not be there. Get that checked asap.

Hi Guys,

The mechanic came today in the morning to inspect my car, he changed all the spark plugs. The fourth plug was dark black so the mechanic said the plug was "shorting". Even after changing all the spark plug, the car was misfiring a little bit, the idle was uneven which miraculously dissappeared in b/w. He came to a conclusion that plug wires also need to be changed along with ignition coil for the last two plugs. He said once the car warms up the coil isnt giving sufficient current. Is his diagnosis correct? Shall i take a second opinion or go ahead with the ignition coil change?
How much do you think the mileage will improve if in present state it was giving 9 kmpl?

Hi,

I think he is right but do not agree about the plug shorting bit. It could be the coil that is faulty.Easiest way go to the service centre and request them to swap the coil by temporarily loose fitting one from another car. If the car feels ok you have your culprit. It is advisable to change to better plugs and wires in the long run. You can check the plug wires for their resistance using a multimeter. This will indicate whether they need changing.

Cannot comment on the mileage but it should improve.

Thanks Dude,
