Hello,
Maxima 3.5L 2009 94k miles. Regular oil changes every 4k miles from previous owner (all documented) with Nissan oil at the dealer (syn blend?).
Got the car at 80k miles. Used M1 EP 5w30 for the first oil change (4k OCI) never noticed lower level on dipstick.
Tried Amsoil SS then in 5k switched to PUP for the last 2 OCIs (3k to 4k each). Town and suburban driving mostly.
Started to see around 3/8 quarts loss on disptick every 2k miles. But engine definitely was quieter on Pennzoil.
Car engine bay is meticulous and bone dry. Never a leak anywhere.
You advice to switch back to M1 EP 5w30? I'm afraid I'll loose the quietness and smoothness of Pennzoil.
I have an OEM PCV sitting in my drawer, thought about that too. Didn't change it yet.
Please share your thoughts
