Synergy,
The fleece filter is used in all the Benz vehicles with long-drain capability. The Benz oil life monitor is calibrated with a full-synthetic (PAO - not US Group III) oil that meets their 229.5 spec. This allows for up to a 2 year or 30,000 mile OCI.
Benz got hit with a pretty large class action lawsuit a few years back because Americans filled their cars with API-spec petroleum oil built for a 6-month/7500 mile normal service OCI and ran until the change oil light came on. Horrible sludge and engine damage problems. I can't blame them for demanding a high-quality oil, as they got hit with a $32million judgement from the just the US class action. I don't know what the Canadian judgement was.
There are US oils made to the 229.3 and 229.5 spec. Mobil 1 0W-40 Euro is available on the shelf and used in Chrysler dealerships. AMSOIL has a couple of products, including their 5W-40 Euro, which is 229.3 today and will be 229.5 in January.
Bottom line here: Use a full-synthetic oil built to the required Benz spec, and the fleece filter, and you can run to the full oil change interval specified by the Owners manual and/or shop manual with complete confidence.
And come over to the VW TDI club - there's a ton of excellent info on Euro spec oil and diesels, and there are a lot of TDIers with Sprinters.
