Scott is right. If you're going to use a topsider, then his way is the way to do it. Now, however you change your oil, just make sure you do it often. Whatever type of oil you're comfortable with, every 3000 miles and your car will do great. (well, do the other maintance and stuff... you know) Just promise us all that you will not run your car with no oil in it. Not even for 30 seconds.
