Audi/VW Oil Filter Comparison

["Donald Scott" <donrscot@flash.net>]

The website cited previously on the list, http://members.xoom.com/_XOOM/minimopar/oilfilterstudy-german.html, now has some info on Mann, Mahle, Bosch (made in the US) and some American oil filters. The author says that the Bosch 72150, Mahle OC49, and Mann W719/5 are all well designed filters with small differences. The VW 034115561A appears to be a Bosch. The filtering area is largest for the Mann at 285 sq. in, followed by Bosch at 278 and Mahle at 259. The Fram PH2870A, which he has a low opinion of, has a very low 173. All have anti drain back valves. For details and later conclusions see the website.
