Hi Members,
I bought BMW 2001/325I series about 2 months ago from a private dealer.What i was seeing strange for a while is about the gas Mileage.I'm using the 93 Grade gas and it gives about 14-15Miles/Gallon on an average(highway and local routes in California).

ghead
Is something that is wrong or i need to do like servicing or Oil-change(it still shows 3500 miles for oil change and keeps droping down as i drive).Everything else is fine.
Any suggestions would be appreciated!!
