my brother in law (who is not normally prone to telling lies)
reckons his diesel astra estate which is two or three years old thinks he's getting 70 mpg
he drives allround northwest of england doing service call work to machinery , hes always had vauxhall diesels and swears hes getting 70 mpg
what so you think
(ps i dont believe him either i cant see him getting more than 50 especially as he has to be there quikly and were talking like shopshire to bradford and that sort of journey

I get 50ish out of mine (1.7tdi) on average.The most I got tootling about was 60mpg.

Lets think about this laterally.
Remember Robbie in the Honda Accord who was only getting about 38 mpg? His car was probably on the bad side of tolerance so although there was nothing wrong, everything in the engine and drivetrain was just not quite right and so the economy suffered a great deal.
Now imagnie if everything is just right and in perfect harmony - wouldn't that give you superb economy? So maybe, just maybe 70mpg is as realistic when usually you would expect 50mpg as 38mpg is for Robbie's Honda when he was expecting 45 mpg.

How does he measure the Astra's consumption? - "brim-to-brim" figures, trip computer readout, miles per "full tank" ....
|
The 1.7 engine in the Astra is exceptionally economical, and if the driver is very light footed and very lucky it's just about on the upper side of believable.
I've had similar mileage out of hired cars: a Golf 1.9 TDi (66 mpg over 450 miles, brim to brim) and a Clio 1.5 dCi (not brim to brim but 1/3 of a tank in 200 miles, again about 70 mpg).

SWBO's Focus TdDi did 62 mpg on a light-footed run to the coast recently and the Astra is reckoned to be more frugal than the Focus, so I could believe it.

As mentioned in another thread, I have the ECO4 version of this car. This is the same car apart from higher gearing and an underbody tray to help aerodynamics. Pottering around to work and back (short 4 mile journeys) with a few longer runs at weekends I average over 55mpg. On long motorway runs at about 80-85 mph I get about 65mpg. For a car of this size, the economy is unbelievable. I have never had less than 50mpg on a tank. The above figures are based on brim to brim calculations.
When the ECO4 version was launched, Vauxhall ran a competition to see who could get the best mpg. From what I remember the person who won averaged 144mpg! So basically yes, 70mpg is achievable even from the standard version with a light foot.
Very underrated in my opinion, no similar sized car can get close for fuel economy.
