I've noticed that, at startup, my oil pressure is 0 for a second before jumping to the normal idle pressure. Is this normal? Is the pressure really 0 for this second? Is it something to worry about? Am I paranoid? I'm hoping this is just an electrical gauge lag issue...
Oil Pressure at Startup?

I haven't really noticed on my truck, but I know that the guages reset to zero when starting. I normally remote start my truck, so I never pay attention to it. I will check mine when I go to work today though and post if I see anything different than what you are experiencing. I think it is just the electrical system setting up, but I don't know for sure.
I checked my truck on start-up and it is 0 for like 1 or 2 seconds then it pops up to 70-80 depending on how cold it is.

it just takes that long for the system to prime. there is no pressure until there is oil flowing through galleys.
Between runs, the oil drains back.

no, just leave the truck running.
seriously, all vehicles do this. I ran a motor for 15 minutes with no oil when i was younger. It lasted another 20,000 miles before the suspension blew out of it. I ran a motorcycle for 12 miles before the motor froze up. I only know this because I spotted the oil trail the next day, and the trail ended 12 miles before. If it weren't for the fact that it was air and oil cooled, i could have gone further. The bike had no dummy light. Boy was i mad.
Good synthetic is suppose to have better pre-lub properties than conventional, FWIW.
