Hi everyone i drove my QQ to Islamabad on Thr and got back on Sat night - all via motorway and would like to share with u the fuel economy going and coming.
Going to ISB:
got Petrol and CNG tanks full. First drove on CNG at an Avg Speed of 120km/h and tank finished at 140kms. I got it filled in Rs.200. Meaning a fuel economy of Rs.1.4/km. Drove it on Petrol rest of the way to Islamabad and within islamabad for 2 days before refilling the tank back to full from F8 Caltex before leaving back for Lahore via Motorway. Again drove it first on CNG and when that finished i drove it on Petrol rest of the way to Lahore and got it refilled from 'Red Rose' Shell in Faisal Town. Following are the stats.
Start of journey: Red Rose Shell, Faisal Town, Petrol filled to full with Unleaded Supreme. and CNG filled to full as well with new Shell CNG.
0km Fuel in use: CNG
140km CNG finished. Switched to Petrol.
Fuel Economy: Rs.1.4/km Avg. Speed: 120km/hr
413km Reached home in Islamabad, Drove another 100km within ISB. Avg. Speed on Motorway: 90km/h.
Avg Speed within City: 60km/h.
513km Refuelled Petrol to Full with Caltex Supreme Techron in 15.4l
Fuel Economy: (513-140)/15.4=373km/15.4l=24km/l
Reset Tripmeter back to 0 and start journey back to Lahore on CNG.
190km CNG finished Speed: 90km/h.
Fuel Economy: 210/190=Rs.1.1/km
400km Reached 'Red Rose' Shell, Faisal Town, Lahore.
Refilled back to Full in 15.77l Avg. Speed on Petrol: 115km/h
Fuel Economy: 400-190 /15.77=210km/15.77l=13.2km/l
So There you have it folks. If you drive ur QQ at 90km/h then u get best fuel Economy of 24km/l as claimed by Chery. I did'nt use to believe it but believe it now as i also get 17km/l in Lahore driving. However there is one other thing i did'nt mention earlier - before refilling car to full in Lahore (before leaving) i already had 7l of High Octane in the tank which also had an effect on the economy besides best speed of 90km/h. This could explain the low Petrol economy on return journey as well (besides the uneconomic speed of 115km/h).
