Terrible 1986 E30 325e Gas Mileage

23/03/2013· Hey everyone, So I bought a 1986 inline 6 325e about 6 months ago. It sat for about four months until I could successfully replace the title. I drove it to school one day and while I was returning home, 3 coolant hoses broke and the drive shaft practically fell out. Those issues have been resolved and I''m driving it every day to school now, but I''m getting horrible gas mileage.
