Ok I just purchased my first BMW when I graduated from college it is a 1995 325is I got the car for relatively cheap or so I think I know nothing about BMWs but would like to know all I can and the first thing I have to do is change the oil I am very familiar with oil changes but never on a high end vehicle the oil I intend to use will be Mobile 1 synthetic but I am not sure on what weight of oil like 5w/20 or what should I run I live in Illinois and heard some go by what climate that you live in but am not for sure and I am pretty sure the oil filter is on top that is just from what little investigating I have done and I would like to know how to reset the counter in the dash that is in the yellow back to green again with out buying a reset tool because I have to make the payments before I can buy cool tools for it any help would be greatly appreciated thanks
