So my City is 2 year old and 20,000 km driven.
Brand new car and no parts have been changed or repaired, except oil/air filter and engine oil.
Recently, I have noticed a drop in fuel efficiency. It used to be around 10 km/l and now it is 9 km/l on average. This is after adjusting for AC, Traffic, Driving conditions etc.
I have also never had any checkup or tuneup on my car ever.
Question: Should I now go for any kind of checkup or tuning for my car? If so, what needs to be done and from where?
Thank you Pakwheelers - you are all such a good resource!
