The switch seemed to work for you that's good
I thought the 15W 40 castrol was a sythetic though?
Just thinking out loud here - but you might have gotten similar results going to a 20W 50 weight oil.
You went up 10 on both ends of the oil going with that 25W 50 veres the 15-40 - just a observation>Cp

CP,
Maybe the Castrol was 10/40. I got it at Walmart, so I'll check. No plug for Pennzoil. This is the first time I have ever used the brand. I went with the 25/50 because that is what they had in stock. If they had of stocked a straight 50W, I would have went with that too. I just have to watch now and make sure the new oil doesn't foam and milk too much. I thought Pennzoil was tied in somehow with Gibbs or Brad Penn or somebody? Anyone know?
