AOA Fellows,
So here I am with a problem to discuss with experts.
I have a Chevrolet Joy MPI 1.0, with 151000KM on odo. The car was working great few months ago with fuel consumption of 13KM/Liter with AC in city and 16-17KM/Liter with AC on Highways, even I have achieved 19KM/Liter on motorway once which was without AC. On that time I was using ZIC oil 20w50.
I thought the consumption is not up to the mark and discuss the same with mechanic, he looked the plugs which are in good condition and ask me to replace AIR Filter with genuine one as I was using non genuine air filter. The car also has issue with its MAP sensor which was changed.
Now from last one and half months I am getting very pathetic fuel average which is 10 km per liter within city and 13KM per liter on motorway and that is without AC? I have removed the CNG kit and never drove on CNG. Further, the car is taking lot of time to accelerate and gain speed, I need to push the pedal more to gain speed. Previosuly I can easily hit 80 speed on 4[SUP]th[/SUP] gear and upon shifting to 5[SUP]th[/SUP] gear I can manage to achieve 100KM/hr but now once I reached on 80 in 4[SUP]th[/SUP] upon shifting to 5[SUP]th[/SUP] nothing happens instead I used to push the paddle more and more to achieve 90.
I have recently poured factory recommended engine oil which is 10w30 from shell and replaced the oil/air filter. Please see the user manual snap.
So looking for expert opinion here before i take the car to workshop, any sort of help would be highly appreciated
Regards,
AR
