    It will fluctuate depending on engine rpm. Should be just above or below center. Right at center when cruising. Mine never goes above or below 1/4 and 3/4 marks.

    Makes sense to me that the pressure could be higher when the engine and oil are cold or RPM is higher.

    Mine has done the same thing on both Tundras I've owned, so it seems normal.

    Yes completely normal to have it above or below when doing anything but cruising.

    Based on your temp gauge it looks like your not in the “cold start mode”. We’re missing the RPM side to get the full picture here but even when warm I’m not sure I go past the middle mark.

    What was your rpm? Have you checked your oil level to make sure it’s good?
