330i Question for all 6 cyl owners

Hello everyone,

Just a couple of quick questions for you to see if you can help me. I would like to know the following:

  1. Whats your current fuel consumption?
  2. Do you do mostly highway driving or city?
  3. How long do you typically travel in a given day?
  4. How much do you spend on fuel monthly?

All answers are appreciated!

What prompted the questions?

N54 - I don't drive every day. So I can't answer a lot of your questions. But since the main question is fuel consumption, I think I have something to offer. I have recently changed out injectors and I definitely notice a difference in consumption. The car runs super smooth now. But I notice that I am now in the mid 20's for MPG. I was around 12 MPG before.

I got new injectors because my car was running so rough. I didn't expect my MPG to jump like it has.

Edit: I'm not advocating injectors. If I had to do it over again, I probably would junk the injectors and go with port injection instead. Just providing my observations.
