Title: Fuel Cost Question
Post by: Kate on 23 April 2011, 16:28:34
Hi everyone!

I've got to pick my daughter and all her stuff up from uni soon. It's about a 440 mile round trip.

I'm buying a 1998 2.5 petrol elite next week. Does anyone have any idea how much the fuel will cost? I will drive at a steady 56mph! ::)

Many thanks for any help! :y

aye, driver / route dependant, at least a full tank, so budget £100 and you should have some left over.

Driven nicely - should do it in a tank.
driven hard - could use 2 full tanks.

i dont know if there is a difference as if you drive at  56 mph it will take you longer to get to where you are going thefore your engine will be running longer than if you drive at 70 mph :y

I easily get 35 mpg cruising at 80 in my 3.0 litre auto elite. If you use 15 of the 16.5 gallons from a full tank you should be getting 525 miles.

56mph should be much more economical than 70, the extra fuel is burnt overcoming air resistance at higher speeds, which increases rapidly as speed increases.
I had plenty of time to travel Sheffield to New Forest a few years back and I was on an economy drive at the time so kept around the 56 mph range - my trip average (on the computer) was better than 55 mpg, and would have been better without a section of roadworks..

Should be about a tank's worth of fuel.

I get 25-30mpg on motorways on a 80mph cruise, tried 56mph behind a lorry once and got 35mpg+ but I didn't have the patience to do it for long. :P

That's very low, I get 35 at 80

As it`s been already said.. low 30`s mpg at a steady 70-75mph motorway cruising in my 2.5 elite estate. Well pleased with that  :y

Our 2.0 Superb has just done its first trip over to North Wales plus tootling about all week, plus a run from Nottingham to Rutland and from Nottingham to south Leicester and has averaged 39.8mpg overall.

On arrival at Caernarfon it had averaged 50.1mpg from Nottingham, although that was max speed 60mph and keeping around 50mph all the way !!

Done 568 miles on that tankful !!

Got to be happy with that really from such a large car

When we went Poland in our 2.0 Omega, that got us from Nottingam to Bottrop in Germany on a tankful, about 465 miles if I remember right

Hi Kate,
Who would know best? Considering you bought itfrom me  :'(, and the engine had been seen to by DLK so it behaved perfectly I can tell you what I achieved on my last long run out. Driven steadily with a fairly light foot and using the cruise control on the mway I turned in a healthy average of 37mpg for a journey of 398 miles of which only 60% was mway. the rest was 25% A class and the remainder B class roads.
Don't forget that you will alwats get better mpg if the AitCon is not on. Turn it off by having the ECO button lit up.
As with every trip it depends on how it is driven so wear light footwear and leave the diving boots at home  ;D.
Last but not least, pulling an independently unbraked trailer will entail you not exceeding 50MPH and will also reduce you overall mpg.
Keep the display showing the Instantaeneous consumtion and it will encourage you to lift the foot off! It worked for me when I was tempted to put the hammer down. The sudden massive drop to single low figures  :o soon made me lift it back off the go faster pedal.
Hope it goes as well for you as it had for me.
I miss it  :'(, even though its replacement is far beyond what I expected!  ;D ;D ;D ;D ;D
