Oil pressure is higher after oil change

Corsairprime

My Oil Pressure is read at the Sandwich Block the Cooler lines attach to, so not sure if it is pre or post cooler. I would guess Pre-Cooler though. As I interpret the Sandwich plate design, the oil gets filtered before it gets any cooling. Checked my pressure last night and 25psi at idle with 189 degree oil temp. If I recall correctly, Nissan calls for no less than 14psi at idle and 43 psi at 2000 RPM (@180 oil temp). Your stats are impressive to say the least. A pretty strong argument to switch to the Redline in my book. I am also considering the Motul engine oil though. I use them for all other lubricants and fluids, where possible.

The centre hole in the oil filter is the exit of the filtered oil and that goes directly into the engine.

For anyone with a sandwich plate and oil cooler the oil flow is this:
• Oil pump
• Sandwich plate
• Oil cooler
• Engine oil filter
• To engine

This is a good setup as the oil filter is the "last in line". (love that song by Ronnie James Dio!!)

Just be aware your indicated oil pressure is not the oil pressure inside the engine (after the oil filter)

The stock design flow is:
• Oil pump
• Engine oil filter
• To engine
