Oil pressure

[johnohio]

I have a 2008 convertible and was wondering what kind of oil pressure I should have. At idle its around 30 and at 60 miles a hour its a hair under 40 when its completely warmed up! Do most of you get the same readings or is this considered alittle low. The car runs great and just turned 5000 miles! Probably nothing to worry about but I thought it should be higher!

That's about the way I see it on my '08 with 35K miles on it.
