Fuel Economy

[landrover dave]

Ok I haven't seen a thread on here about what fuel economy people are getting out of their Isuzus.
The best I have gotten so far is 72l for 700km.
I'm averaging around the 11l/100km

My experience is always pretty close to11l/100km. Can do a bit better, about 10, if I keep the speed below about 80 and add 10psi to the tyres, or worse if I drive above 110. But other than that, seems almost independent of conditions or load, even a box trailer,, although I have not done enough sand driving to get any figures for that.

I agree with John.
I had an Isuzu 110 from new and recorded every drop of fuel used over 111,000kms, returning an average consumption of 10.4 l/100kms and as John said, very little variation irrespective of load or conditions.

I should add that my figures are based on about 450,000km of complete fuel records.

My turbo'd 110 averages 12.6, with a range of 11.4 -13.8

Don't have a roof rack, and run 255/85 km/2s. I've tweaked my injector pump, I guess that is why others get much better economy.

I keep a log of all fuel on my phone, not just a top of the head calculation. Speedo is accurate.

around 11 for everyday use and highway, gets up there towing big loads though:o, saw 18 towing into big headwinds....650,000km old injectors and pistons etc will no doubt not be helping. recently replaced injectors and economy and smoothness/ smoking is way better. still blowing by a lot though:D

I have opened up the fuel pump, 6 'flats' on the fuel screw at side of pump and 3 1/2 turns opening the rack. Worst is 6.8km/l towing a disco 1 at 110kmh with headwind :angel:, average 8.6km/l. Checked speedo with 3 different gps.

I thought I remembers ages ago someone getting 8.5 per 100km after adding a turbo.

My gauge is not working so carry a jerry everywhere. I deliberately ran it empty. I got 450km out of a 60 + lt tank. Which works out to be about 13.5 lt per 100km all urban driving.

Maybe I need to wind the fuel back a touch.
