Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

Big engines, quote your MPG here

Newer smaller diesels are of course miles ahead, but when it comes to petrol engines, the big blocks aren't really that much off the smaller ones.
Stop, Dad has a 3.2 4wd volvo, avg about 28mpg. My 1.6 Alfa 147 gets about 29mpg...... not fair
Though to be fair i drive a bit quicker than he does.
I was always interested to know what the 'optimum' engine size is, for say average driving (30% urban, 70% open roads)
Take 2 extremes; a 1 litre polo will be struggling on the motorway and being overworked in that regard, while a 6l V12 is wasteful. What would be optimum on say a motorway run. 2.4 or so? Lets just say petrols to keep things consistant0 -

Your old man drives his Volvo like an aul fella (does he smoke his pipe and wear his slippers while driving it?). You drive the bejaysis out of your Alfa. I'm actually surprised his MPG isn't much better than yours

I have manage 42-44mpg out of a 2.0 litre petrol in my Porsche 924. But thats motorway driving, normal driving she gets about 30-35mpg.
Your foot is way too light for your car
And I'll have to admit myself - the 20MPG on the 928 was under average driving. A couple of tankfuls were spent a bit "faster" and it would be easy enough to go below 10MPG . And a question - at 170MPH, what car would do better than 5MPG? Probably not many...My ads on adverts.ie

Do a search here there are plenty of thread with opinions on RX-8's, they have a few disadvantages over more normal cars but enough advantages to make it worth it
The smile it puts on my face is worth it alone, same goes for the XK8, I loved that car, always will
Was that MPG of petrol or oil?

During the summer I decided to record all fuel put into my vehicle's to see which was the cheapest per mile to run on my commute. (Others are motorcycles..)
Figures are based on the last 8K miles driven by myself since the end of August.
Overall average was 51.4 mpg mixed driving.
Best was 54.6 mpg to the tank.
Worst was 48.7 mpg to the tank.
Fuel cost 0.09 euro/mile
Im getting roughly the same in a 130bhp Tdi Passat 5 speed.
The trip computer slightly over reads though when you actually compare it to the calculated mpg figure. I do roughly 56miles round trip on good enough roads trip reports 53mpg calculated figure more like 51mpg.
In work these mornings before 7 so very little traffic in my neck of the woods and with a lead foot returning roughly 48mpg by the time I park up.
Some additional things that noticably effect the returned MPG value are the weather.
-If its very cold ill burn more juice in the mornings as the engine takes longer to get up to optimal temperature.
-The diesel I use. I find that Tesco diesel gets less miles to the gallon than than diesel sold by branded filling stations. BTW I work a bit abroad from time to time in developing countries and I notice that they have different types of diesel similar to different RON for petrols.
-A properly serviced car. there is a noticable difference with new engine oil, new airfilter, new fuel filter and of course properly inflated tyres!0 -

So true!!
I used to love my '96 BMW 523, 2.5l, straight 6 pot!
Would bring a smile to my face everytime I'd hear her turn over!!
Driving style: dont hang about; but will cruise when up to, or just above the speed limit!
Averaged about 23mpg for the year I had it!! 40:40:20, Motorway:National Roads:City
Head gasket ending up going on her :mad: and had to buy a car in a hurry!
99 Vectra SRi 2l; shes returning 32.3mpg on the OBC - never did the fill to empty - probably 30 in reality!
But when I eventually get around to changing the car come May (post wedding), Ill definately be going back to a large motor BMW!! Fingers crossed for an M5 - but I reckon the budget today is going to make me cry with the carbon tax!! :mad:
Will be a second hand - maybe 5 years old, but 2.5l + will be the only consideration!! The extra few quid on tax, insurance and petrol; will be balanced out when depreciation is factored in -and sheer driving pleasure is worth it!! (*as opposed to a brand new 1.4 Focus or something*)0 -

And here.Same here.
At least, for the 'everyday' and 'motorway' figures.
My 'acting the maggot' and 'foot to the floor' figures are from the computer; I haven't the necessary driving skills, financial resources, legal representation, or death wish to do either of those for the duration of a full tank of petrol. 0 -

Anything 2 liters or under has no business in this thread!
Well the OP said 2.5, but on that basis.. BMW 520i E39 2.2 1600kg manual
31mpg long trips on M/N roads
25mpg good progress on back road / suburban
5-10mpg estimated by fuel gauge on a trip to hospital, not a fun journey
I heard the 4-cylinder, 2.0 replacement in the E60 (Dame Edna style 5 series) is more economical and has just as much power at the top end, but the lovely noise and torque curve of my little 6-banger are worth every single penny extra at the pump to me. Mainly the nice noise!0 -

Couldnt agree more!! Its worth the feel good factor!!
Now with the carbon tax - its a few more cents but sure feck it!!
Makes the plans for the 5l V8 M5 a lil more costly!! 0 -
