something weird has been happening about the last 7-10kmiles..

ever since i started using the new mobile 1 oil, my oil pressure is gone wayyy down..

when i start up, it sits around 40psi at idle, and will go up to about 60 at WOT..

but after the car warms up, at idle the oil pressure goes down to about 20-25psi.. it will still slowly work its way up to about 57psi at WOT, but i am worried about the low psi just cruisin around.

i have heard from a couple of people that the new mobile 1 is to blame, but i dont want to spin a bearing or anything either..

anyone have any ideas?
