Tested fuel efficiency this way.
Fill the tank. Drive around for 100 kms. Fill the tank again. And compute the mileage with this formula 100/fuel filled in after 100 kms.
Sometimes I checked the fuel efficiency by just driving till the tank goes to the lowest level approximately in the fuel level indicator.
Thank you. :)
IMHO, a 100 km drive and then a tank top / tank fill provides little less accurate numbers when compared to the tank fill on fuel warning light glowing, i.e., around 5+ litres left bank in the tank.
I calculate my Santro's mileabe (35 L tank capacity) only after using 25+ litres of fuel, or after 400 kms (in City Drive). Thus I get at least close-to-accurate numbers.
Vehicle : Hyundai Santro GL Plus
Petrol 2013 March
Drive / Usage : 95% Highway, less than 5% in Chennai City.
ALL FIGURES in TANK FULL TO TANK FULL METHOD ONLY
Highest Highway Mileage achieved with NIL AC (0% AC)
2013 April- Chennai to Bangalore via Krishnagiri @ 70 kmph speed, not exceeding 80 kmph, with ZERO A/C usage was an astonishing 20.96 kmpl
(carried 3 adults including me & a 4 year old kid)
Highest Highway Mileage achieved with 90% AC usage
2015 Chennai to Tuticorin via NH45, NH45B, Excellent Road - 6 lane, 3 adults, 1 kid, 1 toddler. Speed Limit 90 kmph with occassional oscillations to 100 kmph was an astonishing 19.37 kmpl
Worst Mileage I found : 10 kmpl (with 90% AC
Best Mileage : 16 kmpl (with full AC)
Approximate City Mileage with 60-70% AC would lead to around 14 kmpl
Approximate City Mileage with full AC --> less than 12-12.5 kmpl
City Mileage with 0% (NIL) AC usage --> 15+ kmpl
Yesterday's tankfill update:
Tank swallowed 25.503 litres of ordinary (non premium) PETROL for 401.7 kms distance in Trip Meter, which works out to be 15.75 kmpl
Yesterdays' Kelambakkam to Avadi via Vandalur-Minjur By Pass --> around 45-50 kms highway consumption.
One trip to Vedanthaangal with family, slightly overloaded (4 adults, 3 kids, all round 5-8 yrs segment)
Rest happens to be City Traffic, with yesterday's 30 kms b2b from Spencer Plaza to Siruseri SIPCOT TCS office.
AC usage was about 50-60% during the entire 401.6 kms usage.
Overall mileage seems to be not bad or fair.
Other Santro owners - please keep updating.
