Hi there, so last week i changed the oil in my explorer. I had forgot what oil weight i had used last time and someone misplaced my manual so yeah. No help there. I thought I used 10w-40. But not positive. So i checked with ford and they recommended 5w-30. So i used that and now my oil pressure gauge is being janky and oil is leaking from what looks like at the seal between block and oil pan. Thoughts? Recommendations? Thank you.
