Drove WagonR 2015 for around 850 kilometers (LHR-Multan-LHR) major part was on M3 motorway and rest inside Multan city.
On 2nd fuel tank, I decided to keep notes of the fuel average and odometer readings and got average of 17.41 KM/Ltr with 30% AC usage.
Filled the tank on auto-stop from Attock (M3 service area).
1st point remained till 98.6Km
2nd point till 138.6Km
3rd point till 216.3Km
4th point till 257.3Km
5th point till 310.9Km
6th point till 345.1Km
7th point till 409.1Km
8th point till 495.7Km
Then again refueled the tank till auto-stop and total 28.46Ltr fuel was poured in:
Upon calculating the average turned out to be 17.41Km/Ltr which I think is excellent and way beyond my expectations.
Now the main question, How?
Some of my friends said that I must have driven at around 80Km/h speed in order to attain this average.
However, this is not the case.
While on the motorway (around 400Km) I strictly maintained the speed of 108Km/h and the RPMs on 3400. While inside the city, I never went beyond the speed of 70Km/h. Also I have the habit of shifting the gears at around 2000-2200 RPMs so this also plays a vital role in acheiving good fuel economy.
The car is driven 161K kilometers.
Engine oil being used is 10W-40.
Not single-handed driven (used by different people due to being an office car).
Edit:
Wheel Setup - Chinese alloy rims
Tyres: Front 165/65/R13 Lanvigator (China)
Rear 145/80/R13 stock Euro Tycoon
This was just my experience and thought to share with others as well.
Thanks for reading this long post!
