Question oil pressure late?

ok so basically when i get in my truck and start it, it takes ohh 2-4 seconds for the oil pressure to come up where it is suppose to be. it took a little quicker a couple of months back but it just seems that it takes a little too long for it to pressurize. as most of you know, i just recently rebuilt the motor in the spring and i don't want to ruin my pride and joy....and this is NOT happening because it is grabber green.... i am using Mobil1 5w-30 synthetic in it right now. should i go to a 0w-30 for the winter? it is now about 30-40 degrees out when i start it in the morning. like i said it is taking a little bit longer in the colder months now then before and i was just wondering if i should go to a lighter based oil. thanks

synthetic oils dont thicken as much as conventional oils when its cold. You might want to look into some type of heater for your oil pan, or a block heater. 5W-30 Is the thinnest i would even think about running. If you really want to go thinner look at the 5w-20 like the 4.6 and 5.4 use. I run 10w-30 in the winter and 10w40 in the summer in both my trucks.

I agree with what's already been said.. get a block heater and don't go any thinner than that.

what is your oil pressure gauge rigged like
factory, tube to the gauge, or after market electric
if you are using the tube to gauge type then
just a little cooler will cause the time delay
while you have good pressure at the engine

OMG !!!!!!!!!!!!!!!!!!
You start your truck when it's that cold????
I would NEVER start mine at those temp's.
You are going to destroy that engine. You have NO oil pressure when the engine is off, Don't ever try to start it.
Get an electric pump to pre-pressureize it & keep it in a heated garage.

ok i will try and get an oilpan heater of some sort. i can't put it in a heated garage or a garage for that matter because i don't have one. it gets parked under the trees beside my house, and i can't park it where the sun will shine in the morning because the sun rises behind the house in the trees. and pre pressurizing the system? never heard of such a thing.heard of pan heaters, block heaters, remote oil reservoir but never a pre pressuring system. 30-40 isn't that cold. when it starts to get to -10 then it becomes a bit cold

Make sure you are using an oil filter with an anti-drain back valve. If the filter drains it will cause a delay in oil pressure on start up. BTW my 56 F-1 and 48 Chrysler 6 volt started at -5 deg F. Engine block heaters will help in really cold weather and of course gives quicker warmups. A small trickle charger for the batt was also hooked up I had mine set on a timer so it would start heating about three hours before my commute. If it was below 0 I would leave it on all nite. I also put a warning light on the dash to remind me that I was still "on line".
regards and keep warm, 31 deg in Mass

i am using the stock gage. BUT i can hear the engine with little oil in it then it pressurizes and runs fine. its just those 2-4 seconds of "no oil" that scares me
