Im normally a cooler weather (in FL, that's a relative statement...by 'cooler' i mean in the 50's through the low 70's) driver when it comes to my D. Normally I do not drive it in the FL summers because it's so brutal, and i still have my new AC sitting in my living room.
On my last trip to Orlando, with 92 degree weather and the car running between the 220 mark and that 1st line above rest, fans running, I looked at my oil pressure. *Mind you, this is the hottest weather I have driven the car and the longest distance.*
My oil pressure at speed would vary from between the 3/4 mark and half, popping up to say 'hi' to the line directly below the 80psi marker. I know when the car is running that hot and the temperatures outside are that hot, oil temps are running hotter, hotter oil thins out, etc... At that same temp, my idle pressure drops just a hair below the 1/4 marker and climbs steadily (sometimes just below the 80psi for a second before falling into the 'hot' range listed above).
I know these cars are finicky, but im just curious as to what pressure other people experience with city driving in 95 degree heat, and what temps your car experiences.
thanks!

For people in hotter climates, does this reading seem normal?
