hey everyone, first day really driving the Z. amazing. every second. one thing i noticed (something my truck never did) is that the oil pressure gauge goes up and down depending on load. when im on the throttle its right in the sweet spot, usually around 60 in the center of the gauge. when i get off it, it drops. at idle goes down to 30. is this normal?? thanks everyone! so glad i got a Z the yellow is gorgeous.
