Best Fram filter for longer service w/track use/HPL oil

What model cartridge filter was the Mann? I'd look at their website to see if they give any efficiency numbers.

Nothing.

Nothing.

Maybe you can contact M+H and ask for the spec sheet that they have given some people here. The M+H spec sheet shows the ISO 4548-12 efficiency specs.

And back to Mann. The smooshing isn't what I want to see.
