Hello everyone 
 
I have a 2005 Porsche Boxster that seems to be dripping oil somewhere between the mid and rear of the car.  All winter long it has been stored.  My question is how do I check the oil after storing it in the winter for so long.  I didn't want to start the car since I don't know how much oil is really in the car still.  I turned the key just so that the electronic oil level reader would show up which it did, it showed 3 bars which is good but I know that can't be right.  Towards the end of last year I did have to top up oil but I didn't bother to get it checked out since we got a heavy snowfall early and the season was over.
Also if it is just dripping oil, can I just drive it and top up as needed?  I will have it checked out to see what the problem is once I make sure I can safely drive it without having to worry that the car has little to no oil left in it.  I assume at this point a dip stick option would have been nice than an only digital one?
If my engine is cold how much oil does 3 bars really mean?
Thanks everyone,
Signed,
Vin
