My 2019 new Wagon R mileage had the same issue from Day 1 when I get it from Dealership brand new!
First fill up gave me no more than 9 kpl but I kept experimenting.
It currently has done over 2K only on the ODO meter but last tank gave me close to 15 kpl within Karachi city with 50% AC
My instincts say that never stick to a single fuel station and you can only know which one is the best when you test it out.
I just switched from Total stations to Shell and initial calculation revealed that I am getting over 18 kpl from that station which is insane. I will have to consume the entire tank before getting accurate mileage data.
I only refill my tank no more than 25L at a time when the tank shows the last two bars only.
Everything in my car is in stock condition.
- Typre pressure in all four 36PSI
- Just had air filter cleaned with air pressure and also the radiator too.
- I always drive with a soft pedal
- Most of my commute hours are off peak so people getting 12 kpl is more realistic figure for Karachi city.
