Thread: Fuel Economy - 3.5 V8

This thread got me interested so I took the old stage 1 out and drove it at 80-90 Km/h (something that its not accustomed to) I got 13 per 100 on petrol and 22.62 per 100 on LPG. Much better than I thought all I have to do is discipline my self to drive at this speed all the time.

Around town my normal is 19-20ltr per 100 km ops: ops:

But out on the highway it is normally around 16 ,I have had it down to 14.5

Pulling that camper trainer off road.... usually pushes the numbers back to city figures



oh well..... no point in earning it if you can't spend it I figure...

My Rangies Both get around 13L/100km doing highway stuff. And thats through the LT95 (1.1:1 High) and 3.54 diffs I am very happy with that. Out bush they're not bad either.

The carbied V8s seem to be way better on fuel than the 'Injected ones.

With the D3 which is a 4.4 V8, I have been pretty impressed with the figures. At the moment it is around 15.1/100km and that is a combo of highway and urban driving. I would be doing 6-800km's a week. As Captn pointed out, offroad it guzzles more or if I am planting the foot, but after 3 days of beach driving on Fraser the figure rose to around 15.7/100kms.

P.S and yeah go the V8's :wink:

D1 93 V8 auto 280,000ks (today!)

Did a run from home to Beaudesert. Full from home, refilled at B.
Refilled at home after the run. 330ks round trip and I was in a hurry, climbing over the Lions Road, which is very steep and windy.

16.6 litres to the 100. Must need a tune....

I drove from Melb to Perth in a 1992 3.5ltr manual disco in Feb. No A/C (well only for a day and a bit before the gas leaked out!). I sat on about 105-115kms/hr for most of the trip.

I wasn't towing anything, but I had a bit of a load in the back (mainly LR parts :wink: )

Mileage: between 14.5-15.5ltr/100km for the trip - not as good as my 300TDi rangie, but not that bad.

Cheers

Updated figures, currently doing around 13.7/100km which for a 4.4 V8 is pretty bloody good in my books, mind you I am being a bit easier on the pedal :wink: ,

On the highway, I usually get around 15 l/100km out of my '87 RR. That's sitting on 110kph.

I did a trip in January from Sydney to Adelaide towing an empty car trailer & returned with it full.
I only sat on 90kph for the whole trip & the additional weight on the return leg seemed to make no difference at all. It returned 15l/100km each way.

A workmate's father did a trip to Tassie a while ago in his '86 RR & averaged 10l/100km 8O . A week later, he burnt a valve out from running too lean :wink: .
