You didn't say how many miles were on the van, or if the garage replaced the oil sending unit.(inexpensive fix) But if you have over 200K, then I would agree with your mechanic. Probably worn rods and bearings will contribute to low oil pressure. While you save for a new engine or vehicle, I would suggest using a thicker weight oil.
