well today I finally got around to doing what I should have done 2 months
ago when I took my van off the road for the winter, ie add gas stabiliser
and change oil and filter.

I did it and instead of using my usual choice of a Mann W 719/5 filter I
tried, as a lark, a Mann 719/30 filter.

 (not much diff in price)

Both filters look identical, but the /30 has "2 jahre/30,000 km" printed on
the filter.

I am not intending to change my 4/year filter change habit, but I am curious
about what makes the 2 year filter different.

Any ideas?
