Hello, I did a 50 mile run today, about half way I noticed it said average MPG of about 49. Being a hot day I would have expected maybe 60-65. By the time I got back it was showing 43 average mpg. Its an old car but diesel and always got good milage. At one point at about 50 miles an hour it felt a bit bumpy (dont think I imagined it) But I think that improved.
Any ideas what it could be? I checked the tyre pressure and put a basic obd2 on which didnt find anything.
Cheers.
