You need to get this problem resolved especially if the car is going to be a "keeper".
It might be worth taking the car to an independent shop where they don't have a lot-boy changing the oil but a real mechanic. It will cost a bit more but you might consider it a good investment. You might be able to survive paying 10 to 20 bucks more once or twice a year. For me it would also be worth getting away from "bulk oil". The industrial hygiene at many dealerships is a risk.
There is oil pressure warnings.
