I just changed my oil today and switched to the German castrol 0w-30. I made a couple WOT runs on my way to Checkers and when i got to the drive thru, i noticed the oil pressure was really low, like a hair under the first line. On my way back to the house the oil pressure barely got 1/4 the way between the 1st line and the halfway mark. It was not doing this earlier in the day since I was monitoring it. Could this be the 0w-30 oil?

 

yeah could be ur oil, If you changed it and it started acting up, change it back to what worked, Our cars dont recommend that anyways. too thin!
