Well sometimes I get a little more than 40 on the oil pressure. Most of the time it's running really high at like 80 which is AWESOME! 
My temp differs a little. Driving around town I'm always lower than 210 and I don't usually hit 210 until I've been driving for a while, or when I hit the highway.
This summer has been different though. With my A/C on full blast, driving on the highway I have been running 220-230 which is a little high... to cool it down i just turn the A/C off lol

I never use A/C, but thats not the point...it never goes past that mark...When I go into some "quickie-marts" I leave it running because it will stay cooler, than if I shut it off, and let all the heat accumulate, before restarting, and then it will be up to 210, for a few seconds, then it starts to go back down.

I've got an upgraded cooling system and temperature stays always under 190 ecxept when wheeling in 4lo, then it creeps up to 210.
Oil pressure is 60 at startup, 25 at idle and 30/35 at cruise.

his gas gauge must be stuck too cuz mine guzzles too much gas to ever be that full 
on a serious note before my recent overheating problems i was running 180ish and would run 210 with the a/c on in the mojave desert.

With the new radiator mine rarely gets past the 160 mark on temp, and my oil pressure is constantly high.........at least 60. That's a good thing considering it has just over 200k on it!

Well I was having overheating problems. So after I changed everything out I decided I needed a temp gauge. Its not bad just I wish it ran cooler. Its possible something is clogged because when I took the water pump off it was covered in orange rust crap. I did wash everything out as good as I could though.

LOL I constantly get that little yellow light next to the letter "E". It's not as bad after I seafoamed it though. I used to get like 14 city, 17 highway. now I get like 17 city, 20 highway. And I drive with a lead foot most of the time
I like people turning and looking whenever I accelerate at a light hahahaha
