Thread: 3.9 Economy what do you get?

I have a 96 V8 Disco, all the goodies and love it. Live on the Sunshine Coast so AC runs all the time. Half my day is in and out of construction sites, sand and mud.

I get 400 odd out of a tank and on weekend runs 500 odd.

Would like to improve it though it looks like that is about it.

that sort of economy is alien to my 3.9 V8...sorry

8)well, i've been watching this thread for a while,
and my 95 v8 disco, usually gets 15-16 mpg
last weekend the run to toowoomba swap and back it got 18, nearly 19 mpg.
i think someone must have fed it while i wasn't looking!

no, not the ecu

the ignition amplifier, my original one seemed to go alright but i had heavy fuel consumption and occassional stalls. had it replaced and wala different vehicle. good economy for what it was and a lot smoother.[/quote]

Ignition amplifier?? What, where how much? I've dropped to a pretty consistent 20L/100km from where I used to be able to get about 14-15L/100km on the highway.

Hi,
I was getting around 20-24 l/100 or 3-5 km/l on average.
Just took the plunge on LPG and now getting 4.4 km/l or 22l/100 on LPG
A petrol comparison is an estimate, but using 35cents per litre LPG and 95 cents per litre ULP as a figure (Melb metro with safeway/woolies dockets) this is a multiplier of 2.5 so getting 750 km for the price I used to get 350 for on petrol.

Of course downside is shorter range (around 25 - 300) and no use for Jerry cans but hey..... :!:

Well actually, with some newer systems you can decant a regular BBQ gas bottle into your cars tank...still not as handy as liquid fuel, but almost there!

Hi All, did my first economy test in city cycle..........18.5 l/100km. Reasonable I thought for a 5 litre EFI V8, 3 speed auto with air con running all the time[I'm asthmatic] I'd expect around 16.5/100km highway :roll:
I'll have to see when I get to take my first decent run. Besides, that V8 burble is more than worth an extra $6.00 per 100 km it uses over the old 4 cylinder....................... :wink:


Cheers Scott.

Good result Scott, what 5 ltr motor is that, a stroked Rover or GMH 308?

Regards Glen.
