Why are you even thinking about NAPA Platinum oil filter ?

You're going to use a "cheap" oil like Castrol GTX, & buy a NAPA Platinum oil filter ?
NAPA Platinum oil filters are like 2x the price of NAPA Gold oil filters.

NAPA Platinum oil filters = Amsoil EAO oil filters.
& are made for really long extended oil change intervals.
Which you are not going to do with Castrol GTX oil.

My oil change intervals on my G8 have been from 14.4K km/8.9K miles to 17.3K km / 10.8K miles range based on the OLM system.
(I have a 8.8 US Quart oil tank.)
But at about $150 Cdn per oil change; i'm not about to do them prematurely.
& NAPA Gold oil filters have been fine for me.

Best oils available over the counter, IMO are:
Castrol EDGE with SYNTEC Power Technology 0W-30 European Formula from Germany
Castrol EDGE with Titanium 5W-30

Mobil 1 0W-40 European Car Formula
Mobil 1 5W-30

Pennzoil Ultra 5W-30
Pennzoil Platinum 5W-30

I am currently using Castrol Syntec 0W-30 European Formula with a NAPA Gold oil filter.
On my G8 & my former GA SE2

PS: On the Grand AM, I run my oil change interval until the OLM light says CHANGE OIL.
Which last time was like 13-months & 4573 km / 2842 miles...hey, it's my Mom's Grocery getter now.
