With fuel prices being ridiculously high, I thought this experiment might be worth conducting...
I also encourage other U13 Bluebird owners to do it too so we can compare our results
Experiment - Fuel EfficiencyVehicle: 1994 U13 Bluebird LX Auto
KMs: ~187000
Last service: ~180500
Extra weight: Standard Nissan U13 tow bar fitted but actual tow ball fitting removed
Mods: no mods taking up excess weight
Fuel: Shell ULP (91 RON)
Driving type: 67% highway, 33% city
Driving style:
very sedateTyre pressure: 38PSI
Aircon/window usage: None (unless vital)
Cruise control: not used
Current average fuel consumption: Between 9-10.5L/100KM (depending on type, style etc of driving)
PredictionI predict that my fuel effiency will drop below 9L/100KM but range between 8L/100KM and 9L/100KM.
I've removed all the junk from my car and left in all the seats and the spacesaver spare. As above, in order to gain maximum fuel efficiency i'll be changing my driving style to very sedate/granny
I'll be checking/maintaining the pressure of my tyres
weekly and carrying no passengers if I can avoid it.
I've just filled up my tank (until the first click) and reset my trip meter. When I have covered about 500KM, I will fill up my tank again (until the first click) and calculate my fuel consumption. In case anyone doesn't know how, fill up until the first click, reset trip meter, fill up (until the first click) after a reasonable amount of KMs (500ish), note how many Litres go in and how many Kilometres you have covered. Divide the Litres by Kilometres covered and multiply by 100...
Example: 50L / 500KM * 100 =
10L / 100KMI'll post my results probably on the weekend or early next week if I do a fair bit of driving...
Or else, in a couple of weeks.
If other U13 owners can be stuffed, give it a go please
Cheers.
PS - "Mods: no mods taking up excess weight" means that sure I have an aftermarket stereo and tail lights, they are practically taking up no more weight then the stock components would. Say if I had a heavy sub box (that I didn't want to remove for the experiment), i'd mention it under Mods or if I had any performance mods which would alter fuel consumption.
PS - I will not be driving with the aircon on or windows open at any time. UNLESS i'm dying of heat and in that case - aircon on fan speed 2 if doing 80-100KM/H and window open if doing under 80KM/H. Window open at high speeds = increased drag, aircon on = increased load on engine...
I will not be using cruise control as it is more inefficient than holding your speed manually.
