80 series fuel tanks

Main tank 90 and rear tank 45 , I believe most get around 900 to 1000 kms hwy driving

Fuel economy decreases dramatically around town.
I get about 250 k's from the sub and about 550 k's from the main around city traffic. Have just fitted a turbo so to early to tell however economy has gone down a bit but I think that is due to me liking the extra power and sticking the foot into it.
Going to the high country in a few weeks so will do a long distance economy test then.

I get 900k from both tanks 135ltr (90Ltr and 45Ltr) around town. Don't know about highway still to do a long trip but would expect better that around town. (approx 12Ltr/100).

I have a 96 Standard 80 Series - I recently filled up the Sub Tank and managed to put 57L into it - Not bad for a 45L tank. I spoke to the attendant who was adamant that the bowser was accurate, but could not explain where the additional 12L went to.....

Davoe - I reckon Captain is correct - 145 total litres (I thought it was 95 and 50 - but it doesn't really matter). My standard diesel used to regularly get 21mpg fully loaded (with roof rack) on the road (ie not around town, which I guess is also technically on the road!)- that's a bit under 1100kms range. At a speed of no more than 105kmh.

My 2 bob's worth on this.

I have a 1995 80 series diesel with 1HZ engine. Vehicle manual gives Main tank at 95 litres and Sub-Mains at 50 litres - total 145 litres.

Travelled outback last year and for all off road travel including Birdsville and Oodnadatta Tracks, Cordillo Downs Road, Coongie Lakes, Innamincka area - I averaged around 7.5 km per litre. That's around 1000 km for both tanks. On sealed roads (Stuart Highway etc) this increased to about 9 km per litre - around 1300 km per tank.

Vehicle was fairly heavy with roof rack with spare wheel, 2 X 20l water containers, tent plus poles with 3 guys plus gear, 12V fridge, food, water, camp gear, seats, tools, sleeping gear etc inside.

Hope this helps with the travel planning
