Very low fuel average of Nissan Otti 2008/13

[zohaibloona]

Greetings to all readers!
I’m using Nissan Otti 2008/13 which is almost 1 lac KM driven but fuel average is about 10KM per liter with AC on speed of 90 on motorway. Tuning, throttle body cleaning and plug cleaning done recently. Air filter changed recently but no improvement. What can be possible reason while car is being heated up on speed above 110.
Thanks in advance

If car is heating up you need to check if your cooling system is working fine (radiator, coolant level), Heating can also be caused by blown head gasket. Carefully inspect your car's coolant reservoir for mixing of oil in it.

For low fuel efficiency please also get the injectors cleaned (especially if there is rough idling and misfiring in engine). It can also be related to oxygen sensors malfunction.

It will be better to visit a reliable workshop and hook up a good scanner for proper diagnosis of the problem.
