Suggestion
If I reset the trip when the engine is up to temp and I'm already cruising then I saw 39 a couple of weeks ago over a 100 mile run (I know thats cheating).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Managed this on the motorway. Anybody managed more?

POST 2Original post

34.0mpg in my 1999 Carrera and 29.5mpg in the turbo. Both on the motorway at 70mph and car was warm. Reset computer after filling up and that is what I got. You lose about 20% in fuel economy with the 4x4 on the turbo so its what i expected.

POST 3Original post

Over what distance? I got nearly 60mpg once down a long hill with a tail wind!!

POST 4 / ORIGINAL POSTEROriginal post

It was on a flat motorway at 69.9mph officer honest[ ]

POST 5Original post

My was showing about 31mpg as I came down the M4 last Friday. I really was doing 69.9 mph as it was my first trip!

POST 6Original post

David that's magnificent in a Turbo. Best for me was 30 on one of my first show off trips to visit my wife's friends, but that dropped to 24 as soon as we got into the town, and do you know 24 isn't that bad for a 3.6 after all.

POST 7Original post

Routinely get 33-35 on long M-way trips, especially abroad and at speeds averaging 70-80.

POST 8Original post

On motorway journeys at around 80 I get 31/32. If I reset the trip when the engine is up to temp and I'm already cruising then I saw 39 a couple of weeks ago over a 100 mile run (I know thats cheating).

POST 9Original post

Nope. Get about 30 but I can't be bothered doing 70...
