isuzu economy

[rocket scientist]

On a 500km round trip on the weekend I made a point of easing up with the right foot. Kept my cruising speed at 90-93kmh, instead of racing about at 100.
Returned a figure of 10ltr/100km. Fairly happy with that.:)
Didn't take any longer for the trip either!
4 speed lt95.

What sort of fuel consumption is everyone else getting?

[Offender90]

I averaged 10L / 100kms in the 120 with the turbo'd 4BD1 for the last three fills (just under 400L). Majority of the driving was stop start around town, with a handful of 100km trips driving at between 80 - 120 km/h.

Perth to Adelaide loaded with a Trayon and towing a trailer I think I averaged 14 to 15l (that was with a turbo, but without winding out the fuel screw). The trailer had a "parachute" on it tho, and we were driving into strong headwinds - often only managing 80km/h with right foot all the way down.

EDIT: forgot to mention its an LT95 with standard (32") tyres.

Naturally aspirated, untweaked fuel screw, LT95, 33" tyres, often with roof top tent, always carrying a decent amount of 'stuff'. I don't drive for efficiency either.
Best 10.85l/100km, average 12.41l/100km, worst 16.33l/100km.
As measured over the last 36,000km.

Between 10 and 11l/100km over the last 500,000km. Seems to vary very little with conditions. (NA)

1986 N/A 110 LT85 just on 750km per standard tank (standard setting on inline f/pump). Not lead footed driving this as I had a scare at one point (roos and some bloody idiot sightseer out near Gunnedah stopped on the road just on dusk- and the 110 with 33's isn't marvellous at stopping without performing some sort of dance- missed her going sideways at just under 110km).

1984 stage one N/A LT95 (not sure about fuel pump settings) flat out getting 600km per tank (same size as the 110 I think- around 70 litres). I tend to hammer this thing all the way to QLD and back (from Batemans Bay). The fuel economy doesn't seem to change much. Wish I had a rev meter...:twisted:

Pre-turbo was 10.5. Post turbo, 11.6-13.8, average seems to be 12.6.

All with 33's, an r380 and 1.2:1 transfer. Turbo involved twisting the fuel screw up 2 turns then back.. Uses a lot of fuel when you tweak it.. And it uses that energy to crush gearboxes souls. 2" lift made no difference to economy.

Measured with an app on my phone.

In a rangie.

9 litres/100km best ever, only done it once.
10 litres/100km for any open road trip.
11 litres/100km towing any light trailer.
12 litres/100km over whole tanks in winter with short running and driving up 1600m vertical hills to play in the snow. Same when towing anything useful on a trailer.
15 litres/100km worst ever while towing another rangie on a heavy trailer.

1985 110, turbo intercooled, lt95 std tyres. best /around town is 11/100, open rd about the same, if in a hurrry a little more:cool:, worst has been 19/100, this was fuel turned up a bit more, full height 3 ton offroad c'van into big headwinds, trying to maintain 90km/h.

the engine, injector pump and injectors have done 650,000km. i have just recoed the injectors, will fit them next week.

Averaged 12.8L/100 over 7000km on our Simpson/Hay River trip this year, and 12.5L/100 Mt Dare to Birdsville.
13.0L/100 over 6000km Melb-Cape York-Cairns last year.
Rooftop tent and at GVM.

I don't bother filling the long range tank fully unless on a long trip so don't have any accurate figures for shorter trips unloaded.

With a NA 4BD1 and a full load of gear:
Got 12.7L/100 over the 2000km of the Canning Stock Route - most of it idling over corrugations at 20km/hr - I'm still shaking...

[grnrvrs]

26mpg ... or ~10.9l/100km over a few hundred miles on a recent camping trip. 4BD1T w/ LT95 and 235/85/R16 loaded with kiddos and gear for desert camping.

[LR Girl]

My '85 110 seems to consistently return figures around the 10lt/100km (just under 28mpg for those that still use that as their yard-stick) - as long as I keep to 100kph on the open road. Bog standard with an LT95.

[flagg]

Interesting, im guessing everyone in the 10.x range hasn't touched the governor?

[Dougal]

Last tank in my rangie, 8.6km/litre (11.6 litres/100km).

All short running, max trip about 13km apart from one jaunt up an 1800m high hill to drop some mountainbikers off at the top.
This is as bad as my fuel economy gets unless I'm towing several ton.
