Spike, I could be wrong here but I think 90% of Fanus's current driving is around town.
If I am correct, then (on the TB42) that is a fairly good strategy as the torque does peak pretty early, and also 4.4 is not actually all that bad for a GQ in town traffic.

Yes that is correct. :salute:
My Patrol is my daily drive. I do about 11 km per day: Drop laaitie off at school on the way to work and then later back home. Robot to robot short distances... :driving:
(Did also do one trip to Whiteriver and back on last 120l fuel used in calculation).

The Patrols (and I guess all other heavy vehicles) absolutely hate the short drives!
My wife used the 4.8 for a while for dropping and fetching the kids from school - a 16km round trip. The fuel consumption was absolutely eye watering! If I recall I think it was doing something like 3.5km/l. I put a stop to that very quickly!

ODO says 100km, GPS says 104.5km
At 120kph speedo, gps indicates 115kph
Can anyone second this?

I have not had time to compare my odo reading to gps, so I am assuming it safe to say it would be under reading with about 5%?
(So when calculating fuel consumption, the vehicle traveled 5% further than indicated by odo... :think: )

Mine is about 3% at the moment.

But be warned, tires vary some in actual size. Results differ. I have had four different sets of what are all nominally 33", and no two were exactly the same.

Yes I realize that. I see the cooper st maxx 33x12.5r15 is 32.76” (when new)

What tyres do you currently have on your gq?

Mine is also about 3% out. measured 370km on gps which recorded 360km on odo.

Just did a trip to Bela-bela and back for a work function... Filled up in Nelspruit, stopped at Groblersdal to fill up, 6.8km/l :salute:
When filling up before heading home, after driving around quite a bit (dont have exact km's) on a game farm/reserve, consumption increased to 5.8.
I am however very happy with the 6.3km/l that was achieved on the trip back from Bela-bela to Nelspruit, :blonde: think if it wasn't for the hilly parts from schoemanskloof onwards this would also been close to 6.8...
Did average about 100km/h cruising speed.. hardly ever went over 110.
