How good is your fuel economy?

How good is your fuel economy?
Just thought we could all make some comparisons to see where some people are doing better than others, and how they've done it. I'm thinking of making some polution gear disappear, help it run better ect. Also taking about diff ratios, tyre diameters, aspiration, the list gos on.
Lets us know your;
-Engine size
-Year/Model
-Aspiration (if not factory)
-Ks you expect -on the highway -in the city -in the bush
-What you've done to make it better/worse
My Rangies a 3.5lt '89, bog stock ,
70lts gets me 420ks... or 6ks per litre
Not 100% on city/bush yet, but obviously less

if anything the mil spec would be lighter as they are stripped of anything not essential.

5" Springs 35" Rubber - 350ks City, 420ks Hwy
4" Springs 37" Rubber - 350ks City, 380ks Hwy
wierd how the milage drop in the city but didnt change when i went to 37s, actually think it got better ks around town but noticably worse on the highway.
never really calculated offroad but i do know that i once got about 220ks on the beach with the 35s
I also once chewed half a tank in half a day out ormeau (max distance traveled 40ks).

best ive done on highway = 13.3ltrs per 100
around town more like 15 - 20 ltrs
Decent figures reason for not touching anything yet as motor is still very strong after 257,000km

Military landies are heavier than the same body type in civi - stock for stock. Military landies have a one-ton chassis with extra reinforcing, heavy bullbar, extra axle-tube reinforcing, extra electrics (blackout lights, etc...). A mates stock x-mil IIA (converted to a ute with canvas canopy), tips the scales at 1970kg (with 2 31" spares).popeye wrote:yeah, its about right.

Fuel economy, well, I'll do my best.
1983 Rangie 4 door, 3.5 L V8 with std stombergs and no extractors. 32 inch MT/R's (235/85R16's)
With previous LT95 4 speed- 22-25l/100kms (about 320-340 a tank, sometimes a LOT less )
ZF auto about 25-27l/100 kms, about 300kms to a tank on avg. Never botherd to take notice. Once the fuel light somes on, time to refill .
With the 4.4 Leyland job, will be interesting how good it is, not excpecting much and will be enjoying the extra bit of power to bother with.

Hot air = better economy? How the hell do you figure? hot air will make it run richer, meaning you'll be under acceleration for longer. The colder air is, the denser it becomes, and the more power you get (assuming it doesn't go too lean, which is unlikely) If you assume fuel to be a constant, you get more power with colder air, and you accelerate for a shorter time, due to the extra power.removed engine fan for noise but also good for econ
also i dont know if this is right but hot air = better economy
ie: snorkles not the best for hwy
big tyres suck
power steer + air con suck
full time 4wd sucks
old school efi sucks
carbies suck

As far as removal of engine fan - if you get stuck in traffic, be careful. If you do only highway driving, there is no reall problem with removing the fan, but if you have stop start driving, be careful. Perhaps fit thermo fans off something?

130+ rwhp = yee haaa (yeah i know)
I could be wrong but this is how i figure it : hot air is less dense than cold air. efi systems will definatly pick up on this and pump less fuel. dont know how carbies deal with the situation. less power = better economy. the air fuel ratio will (should) remain the same but volumetric efficiency will drop hence the drop in power and the increase in economy. Dont know about acceleration but you dont do much on the hwy, mostly constant throttle. FWIW i'd rather have the extra power. i have fitted a vp commo fan - no dramas with overheating (except when i forget to turn it on )Hot air = better economy? How the hell do you figure? hot air will make it run richer, meaning you'll be under acceleration for longer.
