For some reason I've had low oil pressure at lower rpms lately. Started after I removed the a/c. changed oil and filter with 10w30 synthetic. at idle after it warms up it will some times bounce off 0psi on the gauge.
Could be oil pressure sending unit... Changed mine awhile back after seeing what I thought were lower than average readings on the stock gauge. Readings now look more like what they s/b, again on the stock gauge.
Maybe someone will chime in as to an easy place to hook up an aftermarket gauge to get a true reading.

I have this problem also, but mine started with no changes. Going to be hooking up a mech. gauge next week most likely to see if it's just my stock gauge at fault. Best place to hook up a gauge would be the extra port on the filter adapter.
