What Consumption?

Couldn't find a better place to post

But what sort of consumption do you guys get?
OK I;m more interested in Rover 3.9 numbers nut could make interesting reading

The GT40 3.9Efi seems to vary wildly
A few short runs and a heavy foot and try 8mpg
A run last weekend and about 28mpg (Too many police cars on the M40 to give it a blast so a steady75 / 80. (It does this at 3000 rpm)

Now the car is only 1100kg and not much wind resistance but this sounds better than I expected!

cheers
Ian

My cortina,, on a run can return very good MPG If I put the BP or Shell X stuff in, I have got over 34mpg out of my car the run, put the normal 97ron stuff in and the consumption drops to around 30-31mpg

Aye - I tanked up my 3.5 when I was going to Donington on Shell Optimax (or is it called something else now? - it's all I use, anyway) and got 30.4mpg average over 180 miles of 'motorway' speeds

Must get around to finding a 3.9 or 4.0......

why are you guys getting such good figures. I reckon im getting about 20 mpg on a motorway run. It is set up correctly and its only a 3.5

I'm getting about 12mpg on a 4.6 LPG in a series Landie. Aerodynamics don't help.....

60-70mph on the motorway I was getting 25 to the gallon in my 1000kg Morris Eight, as streamlined a a housebrick, but a little petitie of cross section.
The motor is a stock 3.5 with Edelbrock fannymold and Weber 500 carby, and a trifle undergeared, 4000rpm at 80mph.

I get something around 20-25mpg on my daily commute (120 mile round trip) in my 3.5 landy, with twin 2" SU's, running at about 2200 rpm @70. Running a little rich at the moment though, keeps on backfiring every 5 - 10 miles depending on hills and wind

Drops to around 15mpg around the local lanes.

EFI should help sort out the rich running when I can be bothered to switch the kit over.

that is a valid point

And I tend to have a lead noise pedal foot.
