Oil filter Bosch or OEM Mazda

Make sure to change the drain plug crush washer if you don't do at the dealer and get good quality filters (Bosch, Mann)

In my Turbo, I use what many consider the best oil for gdi engines, pennzoil ultra platinum 5w/30 with the oem mazda filter. Although some aftermarket filters have better filter media, none meet the 22 psi bypass valve specs on the turbo engine.

Since I change my oil every 3,500 miles, the OEM is the best choice.

The oem filters are kind of pricey here so I use bosch or fram ultra synthetic

I believe there was a technical bulletin about this, recommending that the VW installations of the 1.8T be run the way Audi, who wasn't have the issue, was running them. So that meant using the much larger diesel Rabbit oil filter, like the Bosch 72174, or the Mann or Knecht equivalents, which upped the oil capacity of the engine, and then running only synthetic

I looked up filters and Bosch was the superior brand. I use my military discount and buy six at a time through Home Depot since the Mrs. Edge and my son's Escape take the same filter as my 2.5L Maverick. IMO the filter is as important as the quality of oil.

I do a lot of miles in my diesel so I buy in bulk from rock auto and the shipping barely goes up

My last order I made sure to get all of the filters from the same warehouse while still getting good brands like Wix and Bosch

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.

FZ is expensive, but not as expensive as a new transmission. Get the FZ.

bosch will do for a fester, for the more high performance or up market stuff i use mann or dealer and they aren’t that much more, i just had a 340 gt bmw in that ran the camshafts out of the head after 6k on factors oil and filter, the filter collapsed and sent paper fluff all round the engine so had to replace the cylinder head.
