Yes wouldn't you just hate to take one off after say two years and find out it was a Tearolator!
I also have my annual oil change schedule setup for Aug-Sep, a comfortable time of the year to be working in the garage or on the driveway.I'd recommend both your oil and filter annually. It's easy to remember.
Also there is no need for expensive products. A Fram Extra Guard filter and 5 Quarts of Quaker State oil at WalMart will be around $24.
Also , a filter actually performs better as it gets dirty. It blocks smaller and smaller particles the dirtier it gets (provided the bypass doesn’t open).
I don’t drive the car much so the mileage is well below 15,000km when I reach one year after the last change. So I have been replacing the oil every year but I wait until I reach 15,000km before changing the filter, which is about once every third oil change.
I figure it is unnecessary to replace the filter before I reach 15,000km because the filter will not deteriorate over time like oil does because it is made of metal and media material.
....
What do you think? Is it necessary to change the oil filter every year, regardless of the mileage since the last change?
The filter I use is a VW 06J115403Q (Mann W 719/45).
Do you know what kind of media this filter has?
I contacted Mann about their filters their reply was:
"The filter should be change at the mileage listed in the vehicles owners’ manual or 1 year, which ever comes first."
It sounds like a stock response. Is it overly-cautious, or may be just to boost sales? I can't imagine that any company would make an oil filter that would fail after one year.
Oil filters cheap, engines expensive.The service manual for my car says to replace the oil and filter every 15,000km (9300mi) or one year after the last change.

FRAM states to follow what your owners manual says so 1 year is going to be the max.Does Fram say anything about maximum time with the Ultra or Endurance? I’ve never seen any time limits mentioned.
btw, CCTA (Mk6 GTI) is actually a EA888 Gen 2? I'd guess it's a Gen 1....

That's true for air filters, but not true for oil filters. That's been a big misconception for a long time. It's been discussed with technical info many times. Oil filters can slough off already captured particles as they load up because as the delta-p across the filter increases it can can dislodge particles and send them downstream. If you want an oil filter that won't slough off much as it loads up, then get one with a high ISO 4548-12 efficiency rating.Also, a filter actually performs better as it gets dirty.

VW 06J115403Q/Mann W719/45 is the exact same filter like in Europe with (up to) two years/30.000 km intervals. So that filter must last for this distance and, more important in your case, for two years. This VW 06J115403Q says "Langzeitfilter" ("longtime filter") on the can. I bet Mann know how to design an oil filter enduring 2y/30.000 km.
yep, air filters work better as they reach maximum restriction but oil filters bypass as they become restricted..That's true for air filters, but not true for oil filters.

Your service manual is giving prudent advice. The one year interval is easy to remember (mine is in Aug-Sep) and you don't have to keep track of the filter change. In addition you can run a lower priced but very good 15,000 mile filter like a Fram Tough Guard that is only $7.00. If you're well below the 9,300 mileage the Extra Guard at $4.00 will serve you well.The service manual for my car says to replace the oil and filter every 15,000km (9300mi) or one year after the last change.

Yes, oil filters can bypass if they load up too much. But I'm not talking about that. Oil filters will lose some efficiency as they load up, even before they ever go into bypass. I posted a graph showing that in the other thread discussing that phenomena.yep, air filters work better as they reach maximum restriction but oil filters bypass as they become restricted..
Even when oil filters bypass, the majority of the oil flow is still going through the media and being filtered. Unless of course if the filer is basically bypassing because it's 100% clogged. Oil filters can bypass even when new if the oil is thick enough and the engine RPM is high enough.so you get a dirty oil filter and combine that with a cold start in a cold climate, the oil filter probably bypasses for a period of time until oil will actually go thru the filter.
And engines wore out pretty fast in those days compared to now - and filtration and cleanliness of oil certainly does have an impact on engine wear. Many studies show that, and no study ever concludes that the level of oil cleanliness doesn't make a difference. It won't hurt an engine if the filter bypasses for a minute or two, because the oil in the sump is already filtered for the most part. But if the oil cleanliness is much worse, then over the long haul it can make a difference in ending wear.keeping in mind that for about the first 50 years of the 20th century most vehicle didn't have an oil filter, you have to wonder how much difference it actually makes if unfiltered oil goes thru the engine for a few minutes.
