Thread: Best Fuel Economy!

Wow - not sure if you will get better than that - my 86 Classic with 3.5 Carby gets about 25L per 100, but I don't drive it for its fuel economy...

I will be putting a 3.9 EFI engine in it soon - if I get 16's out of it, I'll be stoked!

I get about 15.5 towing a 700Kg camper trailer at 100-105KMH on flat ground and 17 over the mountains which I think is pretty good.

Best I have seen is 14.5 towing. It is a bit hard to know under what conditions as I have a long range tank and conditions change, but this was from Mt isa , Longreach etc.

Recently went to Bathurst from Sydney to pick up a car and I estimate it did 16 over the mountains and through Sydney to and from the Central Coast.
But I only get 20-21 locally, as it is very hilly around Terrigal.

Mods- Thor manifold, Unichip, Bosch gen111 injectors, o2 sensors,free flow muffler, snorkel, standard diameter 245.70x16 tyres, no bullbar no rear step, 2inch lift, air dam on and slots blocked up.

An overall average of 16. Sounds pretty good to me.

Bump up the timing to 12° BTDC

Lose weight, roo bars, roof racks etc

Travel only when there's a tail wind.

I'e more than happy with your figures...

- around 20 l / 100km.

'95 Vogue SE, 3.9 V8, running as Rear-wheel drive.

16 Thats brilliant

I'm lucky if mine ever gets less than 20. 30 on LPG atm

Hi We just got back from a short trip to the flinders rangers from adelaide, did the drive up through clare and the drive back along the national hiway from pt augusta, with some track driving around the flinders, gorges,wilpeana pound. I recorded the fuel and it was 1404 km with an average of 12.6 ltrs/100km. I think it was great. The drive up i used cruise control a lot, which is not the best if going up and down hills, but after that i didnt use it at all just very steady, and judging the "coasting" distance, and gentle on the right foot. I'm going to try to keep a general log at this site, and see how the city driving goes.
hope this helps.
You'll see one fill up was 83 litres, not much reserve there,lol
