Mobil 1 5w20 for a couple of them. One of them was Mobil 1 5w30. Definite improvement switching to PP! Takes me awhile to rack up miles. 30k sum miles on a 5 year old car. haha!

Yeah, it's not too bad. It had life left in it too. It just has less TBN than I would have predicted. I have high regard for PP's TBN retention so now I predict that the car does many short trips. I could be proven wrong again if the OP tells us.
Yeah, my driving is 90% city 10% hwy. Work is only 15min away and i do move the car closer to the building which would definitely be a short trip.
The oil is holding up pretty well which is why they suggested trying 7500 miles.
