Car : 2009 Legacy BR Wagon, 2.5L NA

Tuned or stock?: Stock

Fuel : 95 from wherever's cheapest.. normally Mobil

Fuel economy : Open road driving: 7.5L / 100km (13km / L) City: 9 - 9.5L / 100km (10.5 - 11km / L)

Fuelly stats if known :  Haven't been using Fuelly, but maybe I should

 

My economy stats are based on before I installed my roof racks & cycle carriers. Road trip from Auck - Welly consumed 44.41L for 630km = 7.04L / 100km. My next trip was with the racks installed and a bike on the roof - 24.95L for 279km = 8.94L / 100km... quite a difference!

 

I'm going to test this out again on my next couple of road trips - to Tauranga with 2 bikes on the roof... then again to Rotorua with everything taken off, and see how they compare.

 

EDIT: The other thing I neglected to mention, was that I've also changed my wheels and tyre size from when I got it. It did have 17" rims, now it has 19" rims with a higher circumference tyre, so that will also be affecting the gas mileage.

Driving is harder should drop the figure if you car shows km/L. 

Are you sure yours doesn't read in L/100km. Pretty sure jap cars are usually km/L and nz new ones are L/100km

Car: 2007 BP5 JDM Legacy GT (SI Drive Auto)

Tune: Stock

Fuel: Allied 95 when in Christchurch. NPD 95 when in Hokitika

Tank: 63L on spec sheet. Haven't run it empty for a more accurate number because turbo.

Fuel Economy: 10L/100km around town (I live rural so don't do much actual town driving). 8.5-9L/100km on longer trips. I did achieve 8.4L/100km when I took delivery of the car, and did a leg between Taupo and Palmerston North (bought it in Auckland and drove it down to Hokitika over 2 days).

 

I find the trip meter to be pretty accurate on my car. I confirmed it recently by having done 195km on 17L with 11.2km/L on the dash display. Gives a 0.2L/100km difference.

Happy new year!

 

Car : 2008 Infiniti G37S (Nissan 'Skyline' 370gt)

Tuned bone stock

Fuel : Mobile 98

Fuel economy (from Fuelly) : 9.6L/100km

 

Seems lot of the wagons are not so far off, in many cases better.

 

Been on few big road trips lately and all i can see is it would be nice to have a more practical car than this coupe lol. Going away for long vacation soon but when I'm back in March i'll be seriously looking at a swap or just buy  nice Legacy wagon and sell this Skyline. Lookin forward to being in a manual, turbo subi again  soon haha :)
