I agree with that. My guage starts out high and then levels out to mid to bottom third while driving. However, in your last picture, the car appeared to be idling. The pressure would be low, if the car is warmed and just idling. I ran 20W50 in my turbo last summer, and it reacted great to it; however I had to change it in early fall, because of cold nights. This year I run 10W30 synthetic and a quart of Lucas engine treatment with every change and have not had any trouble.
