Oil filter Wix or OEM Mazda

I saw 10 psi more oil pressure across the board from switching to a WIX XP filter. Did this now on all my cars and have the same results. Pretty phenomenal. I used to idle at 20psi like you and now I idle at 30.

What kind of oil filter are you running? My LQ4 was always 40 at idle when warm, about 50 to 60 cruising. I started using AC Delco filters and ended up just under 40 at cruise and 20 hot at idle like you have. Went to a Wix at my next oil change and got the original pressure back. The Delco filter was restricting pressure. No problems since with Wix

What kind of oil filters are you using? Ac delco filters caused similar oil pressure on mine, switched to wix and now it always has like 45psi at hot idle, and around 60 at cold start.

His initial experience with the Mazda has been pleasant, but it's definitely not as refined as the Corolla. Definitely sportier and looks great, but it has some areas where it's rougher around the edges than the Corolla. Things like having a different size oil filter from the factory than what is sold as the replacement part... Quality of Life stuff like that.

I wouldn’t worry about who does the service. Just don’t use shitty Filters. Use OEM or Wix.

I used the WIX as it looked like it matched the dealer installed filter better. It also has internal O rings that seem to seal it better on the shaft.

For filters I have never been done wrong by wix. Price is right and the quality is there. I converted my hilux to use wix 51515 filters because I was sick of ordering them from australia for $40 each, and definitely not buying the $80 one I could get locally. Now my filters cost me like $7. Will pay for the cost of the conversion in a couple years of oil changes.

A good filter is $15 (I use Wix XP) and I get my full synthetic oil at Costco whenever it goes on sale for $3/qt.

Had a conversation with a WIX rep and was told their best filter is done filtering around the 5000 mile range.

Wanna see what a Wix filter looks like after less than 10k and 1 year of driving. Notice how the paper media pulled away from the rubber support. Notice that the filter has been sucked in.
