Re: Fuel consumption (T30 & T31 2.5LT Petrol Versions)
According to my on screen display I am getting 9.3l/100km, the car is a 2103 2.5L Petrol Auto 4x4, it is always in 4x4 mode but not locked so not sure how that equates (I think its 90% front 10% back with variance if req)
Its driven 28,000 in 1 year and 5 months, I drive around 80km per day for work and around 200km 3 times a week for personal
roads have been around 60% highway, 35% suburb, 5% off-track
Pretty happy with it, I run 98 octane in her since new, still on stock tires with lots of tread left

Re: T31-L 6 spd manual (petrol) fuel meter ECONOMY TEST
--------------------------------------------------------------------------------
Just wanted to share my fuel consumption test. I tried for ABSOLUTE BEST ECONOMY. Would like to hear any comments from owners of similar Exy's who have metered their lowest and average fuel figures.
RELEVANT DATA
No modifications to engine whatsoever, Odometer 43,000 klms. Immaculate service history (Nissan dealer). Tested with 95RON / Castrol GTX 5w professional. Stock 17" on-road tyres, towbar, no bull bar. Cargo Load: driver 90kilos, fuel tank 50%, no passengers, gear approx 12 kilos.
MINIMUM FUEL CONSUMPTION - HWAY
I havent done my best at verifying the consumption meter but I've been getting good displays down to 8.1L/100k on HWAY trips with an average 8.4L
TEST ROUTE
My test route is Nowra to Wollongong NSW via Princes Hwy including moderate hills, windy sections, 60kmh roadworks, no traffic, Ave speed limit is 90kmh (changes thru 90, 60, 80, 100).
DRIVING STYLE
I'm averaging 2000 - 2300 revs across all gears. To keep within this rev range means taking moderate hills in either 6th gear at 85-90 kmh or dropping down to 5th and 4th at much lower speeds ....and very moderate acceleration throughout the whole trip. On this test trip I cruised at an average 90kmh in mostly 6th gear continous hway, no traffic, no start/stops. The engine was never allowed to labour - revs were adequate and the engine seemed to have more torque down low than her specs suggest.
FUEL METER DISPLAY
I achieved 8.1 only very rarely and briefly on this trip and this requires a lot of concentration in a manual. (can not hear the revs with music on or windows down). I managed 8.4 more easily - but still required some concentration. I achieved an average between 8.1 and 8.4 over the whole trip. Keep in mind these figures are per the DISPLAY only.
ACTUAL CONSUMPTION
This was tested for 697 kilomtres of 40% urban / 60% Hway driving with cold starts over 5 days, consuming approx 55-60 litres of 95RON. I filled up with exactly 55L and reset the trip meter. I've allowed for a margin of error (5 litres) because the starting fuel level was not exactly known, there were a few litres already in there. After 697 klms I was much lower in the tank - close to empty.
So I calculate 697 klms over 55-60 litres, or between 12.67 to 11.61 klms per Litre. This equates to between 7.9 and 8.61 L per 100K. I think it is probably around 8.5L since the fuel tank capacity is 60L
This seems too low for noncontinuous urban/hwy driving incl cold starts. So i don't believe it. There's something I have overlooked.
But I defintely think this Bowser test has proven the accuracy of the fuel usage display on my highway trip.
I'm about to add a 20kg nudge bar and semi off-road tyres - so my Hway economy is going to suffer. Still, what makes the ave 8.4L/100 look so good is that these heavy cars can CHEW fuel - I can burn 12L/100k or more if i'm not driving for economy - especially up hills.
Hope I haven't bored you all to death.
