I have recently got hold of a 1999 Mk4 Astra Dti and I'm not sure I'm getting the correct mileage.
From what I've read online these cars are supposed to get 55+ mpg. However, I only seem to be getting around 43-45 mpg.
I'm pretty sure it won't be my driving style that is affecting it. I do an 80 mile round trip to work every day and it involves mostly motorway travel. I don't drive like a loon and most of the time my speed is about 65mph - 70mph. Revs are at about 2600 - 2800.
Are there any particular problems with this model of car that could be causing this or is the MPG I'm getting accurate?
Any suggestions would be helpful.
Edit: Forgot to mention that it's a 1.7 Dti
