If you can get anywhere close to 20 mpg with a 4.6, you're doing well and driving like a granny.

 

hahaha...good one..well now im certain i aint a granny for sure..
im on approx... 12mpg...
i say approx due to my ABS error thats here to stay till i either jump that error<somehow>, so i just have a calculator in the car

 

Cruising mine at 75-80 mph, I can get 15-16 mpg on LPG so that would suggest I'd get 17-18 if I ever ran it on petrol. I can get nearer 18 mpg if I drive at 50 mph but I'd fall asleep from boredom and I'm down to 13 mpg cruising at 70 mph with a 2.5 tonne trailer on the back. But mine is a 4.0 litre not a 4.6.

 

im planning a trip of about 3000kms in the coming months....
need to figure out the damage to my pocket well in advance since its the first time im going such a long distance with this car....:shock:
will just change plugs a few weeks to it all and have a petrol tanker follow me from a safe distance...

18 ltr per 100klm is my best around city which is not too bad...I think that's about 16 mpg in your neck of the woods

 

I reset my trip computer on a 120 mile round trip to Heathrow a couple of months ago.

I was running on LPG most of the time, but I did see 20.6mpg on the trip computer at one point. Was pretty much straight cruising at 70mph (ish).
Around town, it generally averages at about 16mpg.

I drive it fairly sparingly at the moment as I have a slack transfer case chain that skips if I get too excited with the throttle..

Oh, and mine's a 2001 (Thor) 4.6.

 

Up in Yorkshire at the moment and the 245 mile journey up here, the mpg was reporting 22.3 overall. That was an average speed of around 75mph on the motorways. I was impressed with that, and on a long journey, that's generally what I get.
That was also three adults, a dog and a boot full of cases and camera gear.

Don't do enough decent runs to be sure what its doing right now but my year 2000 4.0 HSE will get in the region of 22 to 24 mpg for a full tank on motorway and A road duties. Don't hang around but like to keep it rolling rather than push up close in traffic. Motorway 65 to 75 mph region, A roads 50 to 60 where I can and no banzia overtakes. Five minutes here or there matters not and you hafta go some to really make useful time.

you guys run on what that display in the cluster says?.... I would be without diesel 100km before the fillingstation....

My tripcomputer states the fuelconsumption is 9,2 lit/100km (25,56 mpg) in real, calculated from what goes into the tank and what amount of km i've driven it consumes a lot more: 12,5 l/100km (18,82 mpg)

 

Roger my calculation is based on fuel in tank and actual travelled.....never trusted electronics for accuracy in any of my vehicles

 

in my VW it works rather well, maybe 0,1 lit/100km off and the "km to empty tank" option is accurate enough to get to filling station with "0" on the display 2-3km before the station ;-) been there a few times ray:

 

I take the readout as a 'rough guide'... the last time I went on a long journey (1400 miles in 2 weeks) I actually worked out the miles done, the fuel used (LPG and Petrol) and worked out an average of about 19mpg for both petrol and LPG.

 

Must be our lousy ethanol laced fuel but I've never seen better than 16mpg hwy. Though I rarely drive at or below the speed limit.

 

dont forget that in the USA there is 3.8 ltrs to the gallon whereas in the UK there is 4.5 lts per gallon

 

Sat at 70 on a recent 170 mile trip from full to fill up again got 21.3mpg........computer was saying 22.7 .....

 

I keep trying to work out my MPG but I just can't stay sensible with the throttle. Lots of boy racer Clio's and Corsa's round our way and they like going into the turn right lane at traffic lights, to go straight on, thinking I've got a slug of a 4X4 and, as there are a lot of farms roundabout here, its probably a diesel (no offence to diesels), so the 4.0 V8 has to burble and sing in sport mode, you know just to put them in their place. Preferably in my rear view mirror, , but if I can be sensible I can get up to a heady 15-16 Mpg round town and cruise control at 70 will see ~19/20 after a few miles. :dance:

 

The PO of my 4.6 said he could get 19-20mpg at 68mphon the motorway - that was about right but it takes some persistence to stay at that speed!

that persistence is called "cruise controll" ;-)
