as the title says

 

Oil filters or what are you talking about? I use Bosch oil filters for my FD when I dont have any Mazda filters handy.

 

I use them, from the reports I've read they are good quality, and I believe they're made by Filtech.

 

I have used Bosch Premium but IIRC they don't have a great anti-drainback valve so they make a mess when removed. Generally though I like them because they have the same filtration claims as the Mobil1 filters for almost half the price.

The Mazda filters change without spilling more than a couple of drops so I've been happy using them instead.

 

so would you prefer bosch or mazda?

 

Mazda.
