It is a mileage test done under the most ideal conditions, as described by me in another thread: http://www.team-bhp.com/forum/techni...ml#post1948082

Select a leisurely Sunday morning. Take your car to the best bunk and fill it first up to auto cut off. After auto cut off, make them manually fill up to an inch below the fuel lid. Wait for about 15 seconds to see if the tank "burps"! If it does, fill some more till it comes to an inch below the lid. The visual level is important. Inflate all tyres to 32 PSI.
Set the trip meter to zero and take the car on a nice highway where you can drive at constant speed in 5th gear without many gear changes. Drive for 50 KM at a steady 70 KPH, either alone or with one companion. AC can be on or off as you wish, but keep the windows rolled up. Take a U turn and return to the same bunk and same nozzle. Again fill petrol as described in para 1. Divide the distance covered (100 KM) by the quantity filled. This will give you the best mileage your car is capable of under the most ideal conditions. If the figure is good ( I bet it will be > 20 KMPL), there is nothing wrong with your car. Safely knock off 6 - 7 KMPL from this figure to arrive at an approximate city mileage figure you can expect under "normal" city traffic.
It would be even better if you can do this three times with a gap of three months in between, and take the resulting average!

Started out with a full tank of Super unleaded from Shell, reached Pondy via NH 45 and topped up the tank with 6.90 litres of Speed 93 at the Ashram bunk. Distance covered 144.4 KM, mileage recorded 20.92 KMPL.
Returned to Pondy from Sirkali the next day and again topped up at the same bunk with 13.23 litres of Speed 93. Distance covered 216.8 KM, mileage recorded 16.39 KMPL.
Arrived at the same Shell bunk in Chennai via the ECR and topped up again with 6.910 litres of Super unleaded.Distance covered 146.6 KM, mileage recorded 21.22 KMPL.
Total distance covered 507.8 KM, fuel consumed 27.04 litres, overall mileage 18.78 KMPL. | Quote:

Entirely city driving, though not bumper to bumper, with mostly 2 pax, sometimes 3. Full AC. Not bad, I thought, as I don't drive daily and considering the car is parked in the open, there must be evaporation loss as well.
Then just for fun, I set the trip meter to zero and went for a highway drive on the Chennai bye-pass road. Comfortable drive at 60 - 70 KPH and switched on the AC only for the last 12 KM as it had become very warm. Arrived back at Shell and filled the tank again. She took in 1.520 litres till the brim. Distance covered 45.8 KM, so the indicated FE was 30.13 KMPL!  My heart simply refused to accept this figure! So I went in to pay the bill, then told them to clean my windshield. All this took about ten minutes, so I opened the petrol lid to check. The level had gone down slightly, so told the attendant to top her off and she did. This time car took another 0.24 litres, and the recalculated FE was 26.02 KMPL. Finally satisfied, I went home!  |
As it is a Shell bunk (no crowd, you see!), I can afford to wait for a few minutes to see if the fuel level settles down and fill some more if necessary. Since it is a visual level I feel it is more accurate than the auto cut off, and you can see this 26.xx KMPL repeated twice under such "test" conditions. And a lower figure during an actual outstation trip!
@dhanushs
I am perfectly willing to do the same test in your presence! Just PM me whenever you are in Chennai!
@Amit_mechengg
Speed maintained at a constant 70 - 80 KPH for the test.
