I plan to mix 1 qt of Amsoil Signature Series 5W-30 with 5 qt Mobil 1 EP 5W-30. Purolator Boss Oil filter. 2017 Impala Premier next oil change after running Pennzoil Platinum currently. Thoughts?

I have been using the AC/Delco OEM filter. Will the Boss perform better?

Impala Premier. 85000 miles
 
Thoughts?
Don't mix the AMSOIL in, you'll waste it. Mobil 1 EP 5W-30 is very good oil and can hold its own.

Purolator BOSS is made with synthetic media. Will it perform better? That's debatable. It will last longer though, for sure.

If you do 5000 mile OCIs, it doesn't matter.

The Amsoil will bump up the TBN.
No, it won't. It won't do anything for you. It'll be wasted.

It should bump the virgin TBN from 7 to 8
 
I plan to open up the AC/Delco filter when I take it off.

The boss filter is rated at 99% at 20um - or was. I don't think the AC Delco has an actual rating that I have seen.

Never was that efficient ... the Purolator ONE is that efficient however. Purolator claims 99% @ 25u on their website for the Boss, but that's on their gigantic 30001 model filter. Look at the very bottom of the webpage for the statement.


Independent lab ISO testing showed a smaller Boss to come in around 63% @ 20u.
