I usually wait till the tank gets near empty so that I can reduce the number of trips to the gas station. I pull in to the gas station, fill 'er up and get back on the road. Pretty mundane story, except that the car drives smoother with a full tank. Now, it wasn't riding rough before I filled her up and I can't 'feel' the deterioration as the tank gets progressively empty if my life depended on it, but I have been feeling this for the last 5+ years.
Maybe the feeling is purely psychological as I feel 'ready to hit the road' with a full belly. But none of the other cars I have driven...
Curious to know if someone has had a similar experience. BMW thang? My fuel pump?
