Oil filter Mahle or VALVOLINE

Anyhow I would be interested in going longer drain interval, so I think that I will check out these new products Mobil is offering. Although I think the Mahle filter that has been in use is filtering well enough and the price is right at $5.

I just bought 6 MAHLE filters for my 8v, at what I think is a damn good price. The guy I bought them from (a fellow Digifanter) says this brand is the OEM filters of the new VW/AUDI/SEAT cars in europe.
