H6 Oil Filter and extended Drain??

Went to the dealer yesterday to pick up a long filter and the tech recommended the H6 Filter (p/n 15208AA031). This thing is fat! It may work better with my skid plate since its shorter and from what I can find it has a larger filter area, 201 vs 141. So I'm curious if 5000 mile intervals would be ok with this filter?? I'll post some pics later.

Only one way to find out. Run it to 5k miles and cut it open to see if it's clogged yet

i think the h6 has 7500 mile oci. So in theory you should be fine

Subaru moved away from the fat filters on the turbo cars especially, due to the fatter one putting the wall of the oil filter too close to the header and cooking the oil inside it...

Even the cheapest $4.00 FRAM oil filter will easily last for 5000 miles.

I would not run Fram filter more then 3k. IMO

I finally got around to pulling both of the Banjo filter bolts. The turbo one was about 50% plugged. And the driver side ACVS unit was 25% plugged.

Pic. of turbo Banjo filter. Over 73k on my GT




I stated this earlier.

But change my mind. Do to my oil\filter change history. I put new filter bolts in to see if the clogging took place more in the first 30k Mobil1\Fram or the last 43k, using Amsoil oil\filer.

Amsoil 0w-30 SSO and Amsoil Ea oil filter, Ea15k13 oil filter at 30k-73k .
At 73K, my filtration I use.http://legacygt.com/forums/showthrea...ons-81741.html My oil system now is 7qt. I add 2-4qts over the 15k OCI.
Oil consummation hasn't change sense car was new.
Most off the shelf oil filter, filter down between 20 & 40 microns. Amsoil full-flow oil filter is 15 microns & Amsoil By-Pass oil filter is 2 microns.
This filtration system add 2qts. of oil to you motor. Which help keep the oil cooler.
In short, check you oil level often & top as needed. Use oil & filter that will protect for the OCI your running. OA's is the only way you know that your oil & filter is up for the challenge. After that IMO no OA's are needed.

Another 4k I will have 100k on this set of banjo filter bolts. Then I will inspect & if all is fine. I will leave them out. If I have crap in them. I but new ones in & change them out every 100k.

The deposits are largely due to degraded oil and not the filter falling down on the job. I've cut open a number of filters over the years and none of them looked clogged. This includes Amsoil EAO filters with 15,000 miles on them.

I'm not surprised that Amsoil kept the filter screens clean. A friend of mine has over 200k on his 2005 WRX, using the Amsoil 0w-30 or 10w-30 and an EAO filter, changed every 10,000 miles. I don't recommend running quite this long due to the TSB from Subaru. However I have no doubt that oil quality is the main factor in preventing this problem.

PAO and/or ester based synthetics (Amsoil, Redline, Motul, Mobil 1/0w-40, etc) are superior to Group 3 oils when it comes to oxidative and thermal stability.

OMGHiTed!
Wow, all it took for me was two 8k mile runs on SSO (on a turbo with only 20k miles on it), with an EAO filter, and my turbo was done!

I'm guessing the filter getting too hot from the header wouldn't be a problem on an H6. Should be fine to 7,500 miles, IMO.

Dennis,

I doubt the oil had much to do with the turbo failure at such low mileage. However, for a modified WRX engine I would probably have advised running something thicker than a 0w-30. Particularly if you were doing some off roading on the beach. My friends WRX is mostly used on the highway (about a 30 mile commute each way), so fuel dilution isn't an issue.

When in doubt, go with a thicker oil. At worse you'll sacrifice a bit of high rpm performance due to the increased pumping losses.
