Hey all! Just wanted to update on the behavior of my oil pressure after my pump was replaced under warranty. So:
I have noticed that when driving normally (no WOT pulls, just driving the car through traffic), my hot idle pressure is the expected 29-31 PSI at all times. However, I have noticed that if I'm driving the car hard (which I do, even on the street, I drive like the 20 year old hooligan I am) my idle PSI drops to the mid-high 20s range. This is ONLY noticeable directly after putting the car under high load such as WOT pulls.
In the two videos below, I have shown both scenarios. The first video is directly after several WOT pulls (in Mexico ofc
), and the second video is no more than 5 minutes later when I pull into the garage. In the video showing oil pressure directly after WOT pulls, I also give it a few revs to show what the pressure is like under a little bit of load. I've also displayed the oil temperature in both of these videos to give everyone an idea of the amount of load put on the car immediately before filming (in the post-WOT vid, you can see that the oil temperature is quite high relative to normal idle levels).
So, is this concerning behavior, or is this expected? Once I return to normal driving, the PSI always returns to that consistent 29-31 level (as shown in the second vid). I suspect part of this might be due to the choice of 5W-30 oil by my dealership; given how I drive the car, I think I'm going to swap this out with 0W-40 this week.
I would love to hear anyone's thoughts on this!
Here are the videos,
