What is your oil pressure after oil cooler install?

Not sure if this will help you, but I recently experienced a weird oil pressure drop after a road trip. (I have the Z1 25 row cooler) Generally, when the oil is heated up 90C (194F), I was seeing around 15psi at idle and 30psi at 45-50 (113-122F) degrees Celsius at idle. All of the sudden after my road trip idle pressures are now 15psi at 50C and 7-8psi at 80C.

Don't know the reason for this, however at least you can benchmark your oil pressures off of mine. FWIW I changed to Mobil 1 0W40 at my last oil change and now have about 2500km on the oil.

That sounds really strange. Oil pressure shouldn't change like that unless I'm reading your post wrong.
