what's the normal gas mileage on a 1990 535i considering if everything is running fine and normal?

i test drove one and when i pressed the AVE MPG it said 11.5 or so... is this for real or it needs a good tuneup? 11 mpg is insane... even if it's a 3.5L


I had the same question about a month ago.
I was conserned the 535 vs 525 and would be to costly driving the 535, 400+ mile a week back and for to work.

As it turns out I did by a 90 535ia and so far I have been averaging 22.8 mpg when I do the calculating and the computer is showing 21.4.
I should mention the driving I do is a good mix of local and highway.

As it turns out I am glad I bought the 535 with the added tork and not the 525.

I do remember reading if the O2 sensor is bad then so is the milage. Check the archives.

Anyway, hope this help.
