Offroad Fuel Consumption.

**Dougal** · 9th April 2013, 10:52 AM

If I take my 93 RRC for a 25km road jaunt (hilly and windy) which leads to a 1600m vertical mountain climb (about 16km, half an hour, 30km/h typ speed), how much fuel can I expect it to drink?

The return journey is pretty much engine braking the whole way down and then the same 25km road trip home.

My 4BD1T manual version uses an insignificant amount more than normal short running when treated this way. But I have no yardstick for the petrol V8 and auto.

Another question, can I expect the auto to have significant problems with extended climbing on an unlocked TC?

The auto should be fine. That is a normal climb around these parts. I never seen anyone have a problem.

I usually assume double normal fuel consumption off road for the V8s.

So we could call normal 15 litres/100km and offroad about 30 litres/100km?

If 15 litres per hundred is your normal on-road useage... you've got nothing to complain about when it doubles for the bumpy bits.

Think I may take I somewhere to get tuned!

I don't know yet. I've only done about 200km in it and don't want to completely fill it to check.

I put 20L in and the fuel light goes out for a little bit.

But over winter I plan some drivetrain work on the diesel. This leaves the petrol as my "go play in the snow" wagon.

I wait till it gets under 1/4 tank, memorise the position of the needle....and re-fill with 20 litres... Re-set the TRIP meter and drive for 100km. .- See if the needle ends up on the same spot. So far, this method is 'proving' what I already know, mine uses 20 litres per 100km.
But since I've switched to E10 (95 octane) I reckon its doing a little better.

Like you , I can't afford to fill my tank.....

Yeah, but that's kiwi dollars, not real ones. Even so, that's about $1.75 Aussie?

I don't get paid in Aussie dollars.
