So I noticed a difference in pressure the last 2 days on my truck. It is a 1951 GMC pickup, with a 228 inline 6 engine (full-flow oil system) and filled with Rotella 30w.
The first night I let it warm up at idle for about 10 minutes, and then drove it around town when I noticed the oil pressure was at about 35-40#.
The next night, I started it up, let it warm for about 1 minute, then drove it around town and this time the pressure was at 55-58#.
Any thoughts? I haven't seen it spread out this far before, and I don't have any major oil leaks.....
