AOA,

Can someone please help me.

I am only getting 10km/l on long routes with ac, as per my knowledge it should be around 14 or 15, can someone please tell me the cause of poor mileage.

I am driving Santro Club gv 2004 in Islamabad.

Get it tuned, plugs, air filter. Check for friction in the car, can be many reasons. especially can be caused by the way one drives

I installed new NGK plugs, new air filter, recently tuned 2500 kms ago.

Doesn't run flawlessly? When you floor it, is there a delay? Do you drive with a light or a heavy foot?

Walaikum Salam,
Was the car CNG fitted ?

The car is CNG fitted. The car drives fine and I drive with a very light foot and I am the new owner of this car

Cng fitted cars have bad mileage, get it petrol tuned from an expert, remove the kit and then enjoy it.

new air filter, spark plugs, fuel filter, injector cleaner, octane booster, cleaned TB, correct and clean sensors, correct tire pressure,7-800 idle rpm, no current missing, healthy coils, and light foot are some factors contributing a little to fuel economy

Any good santro mechanics in Lahore, I personally don't like Hyundai Sajjad in lahore.

And, can removing CNG REALLY HELP WITH FUEL AVERAGE? Advices please

If the car is CNG fitted, the following things might be affecting your fuel mileage negatively:

The amount of air reaching the engine restricted by a good margin
The reduced spark plug gap
The extra passenger at back at all times (cylinder)

If you want the optimum economy, start by removing the cylinder and correcting these things. You can leave the kit and all wiring intact.

Can tunning be disturbed? I mean I just had it done 2500 kms before and I remember the first time after tuning I had a very good average, but then with every day it started to reduce.

So I really do not know what is disturbing the fuel average. I have had it checked twice with the computer and everything was ok.

But recently my car has been constantly knocking on petrol, knocking sound is very low. I have even filled half tank with high octane, but the knocking is still there. I have also installed a new petrol filter.

Santro has very poor fuel avg

We had one about 10 years ago

I remember it consumed more or less near our honda city dsi vario

My advice
Better to replace it

Salaam

Yours wasn't a decent car then. Have seen and used countless of them, the old shape gives around 21km/l at long and the new shape around 16. In local the new gives 14 whereas the old gave 17. These are one of the highest economy figures for petrol engines.

Thankyou all for your comments

My Santro 2008 giving me 13-14 km in liter and 17-18 on long route,

there you go.

your problem

saboor73 (saboor) 2015-10-20 18:32:01 +0500 #18

Advance timing?

deusman (deusman) 2015-10-20 21:28:33 +0500 #19

What do you mean Xulfiqar?

as to my understanding you have a FF cng in your car so there must also be a timing advancer please check it , it might be faulty. santro only knocks when there is a timing issue and timing issue can arise due to timing advancer.
