I was researching some items and discovered that the filters used on old (1960s) Simcas and Citroens were 30% more stringent than the filtration used on 1980s-90s Mercedes diesels!

What are people using now in their diesels, I am curious.

This will also make me review what I'm using in other cars I own.

Does anyone use any oil filters with 5-10 micron filtration ratings?

I'm very curious.

Thanks.
