Ignore change interval displayed on oil filter?

[jigen]

My sister has a very base 2011 Jetta with the 2.0 engine. For the engine size this car has a big oil filter on there. On the factory filter it says to change every 30,000km which comes out to about 18,000 miles.

Her car will probably do about 12k per year with an oil change every 6 months. With a filter this size would you change it once a year or just change it whenever the oil is done?

Be interested in seeing the responses here. I was thinking of getting some of those Amsoil filters and leaving them on for 2 OCI's.

You should follow the 'vehicle' manufacturer's oil and filter change recommendation while under warranty.

After warranty if you want extend the oil and/or filter's interval beyond vehicle recommendation, your call.

Cheap insurance, Id change it. Im sure itll last for the 18k as stated, maybe do an oil dump at 9k to be safe and leave the filter for the whole run?

If you're going through the trouble of getting under the car, change the filter.

Kind of an opposite, easier, approach is to ONLY change the filter two times per year, leave oil in there for 2 years. Must use a microGreen oil filter (parallel path filtration) to do it. BTW, I don't sell it.

Seems like an excessive change interval for the filter. Maybe if it was pure highway mileage with a new engine. Take the driving conditions into consideration. As others have suggested, just change the filter with the oil change.

i would much rather run the filter for 2 OCIs than the oil. the filter may remove more particles but it doesn't replenish TBN.

Actually, when you add oil to top it off, you replenish TBN. also, you could discard the oil inside the filter each time, forcing more top-off. Microgreen claims to have studies which show micro-cleansing (filtration down to 5 microns) does work very well, although i would only do it with a good synthetic.

18,000 miles sounds a wee bit long unless it is an Amsoil or other really high-end filter. Who makes the filter on this car?

OEM would probably be a Mann, Mahle, Hengst, or Bosch, and it's probably a fleece filter, more than capable of very extended OCIs.

Exactly. Just because it says "up to 30K km" on the filter, it doesn't mean you should ignore the owner's manual, especially when under warranty. Just because it says "up to 15K miles" on M1 bottle, it does not mean you can safely go this far between OCIs and keep your warranty intact.

To the OP: change the filter when you change your oil, at the mfg recommended interval.

I never planned on taking the filter past the 10k recommendation but I won't be taking the oil that far, that's the only reason I brought it up.
