Mann Oil Filters W719/30 vs W719/5

I don't know if they've changed anything since then:

The last round of 719/30's I bought had "2 years" embossed on them in
German.  There was a thread on here a while ago, seems the Europeans
aren't as anal as Americans when it comes to oil changes, they normally
only change the filter ever 2nd to 4th oil change.  For a couple extra
bucks I think I'll just keep up with the "overkill" and change every
time.

I live on a one-way street that's also a dead end. I'm not sure how I got
there.
