Hi all!

I never really took much notice about the oil pressure reading upon start-up until recently. I know the greatest stress on an engine is on start-up when it is less lubricated, and I was wondering after a long or over night sitting, how soon or how fast should the oil pressure needle jump from 0 to 3? My 190E first goes in between 0 and 1 and then jumps to 3 within 2-4 sconds. What is the normal time it should move up to 3? Is it immediate upon start-up? My needle has a few seconds pause before it does. Thanks.
