I think you're due for another oil change. With that Fram filter, who knows what can happen? Also, I actually don't mind the Super Tech filters Wal Mart carries because they're manufactured by the same guys who make Motorcraft, AC Delco, STP, Mobil 1, etc. The differences are how much oil pressure they can take and the filtering media. The little seals to keep the oil from flowing back to the oil pan gets better almost always with price increments, but it'* not that big of a deal to me.
Here'* how poor a FRAM is on the inside:
You can see how the filtering goods are not nicely separated. I think they may even fold over because of how loose they look. Your best bet, if you have no other option but Wal Mart, is most likely to get a Super Tech filter and any name brand 10W30 oil (except for Pennzoil and Quaker State) and then do a sub-3000K mile oil change.
I had a similar problem recently with an AC Delco filter an fully synthetic Mobil 1. I don't know what happened. I then used a Purolator (superior, IMO) filter with Mobil 1, and everything was all right. I just don't know what happened.
