When driving my daughter to school this morning, I noticed that as the RPM's increased so did the oil pressure. It would shoot up to the first thick line after 40 very quickly, but as I drove it more it went up slower and not as much. When I got back to the house, I reved the engine some and it went up but not as much as it had originally. I have a 2004 TB with 125k miles on the 5.3 V8. I did an oil change about 6 weeks ago and it has been fine including on a vacation to Hampton beach NH. (Around 300 miles round trip.) I have a video showing it going up sitting in the driveway but keep getting a unsupported format error when I try to upload it.
