Every document I've read now related to changing the oil on a Subaru states to NOT over-tighten the new filter. That being said, how tight do you guys do your filters? How tight is "Hand Tight", tight enough you could still rotate it further basically?

Do people here have preferences with OEM/Aftermarket filters? Checking scoobymods, there are like 7 different aftermarket filters for the turbo subaru, and fram's filter is even 68mm (instead of the old 80mm)

If you haven't already, read this thread for more Subaru oil filter data than you'll ever need:

Cliff's Notes: the standard Subaru OEM 15208AA080 filter is very good.

I have owned many high mileage trouble-free cars. I never filled the oil filter, because they were mounted horizontal.

The wrx is the first car I have owned where filling the oil filter with oil was possible. I do it now because I can while the old oil is draining. Plus the wrx is the first car I have owned where I don't have to raise the car to change the oil/filter.

Does pre-filling really help? Probably, if you drain the old oil overnight and there is no more oil film on the surfaces.

So, I do it because I don't like seeing a red oil light come on for a couple of seconds after I start the car with the fresh oil, and I change the oil frequently.

My other cars where this was not possible, ran well over 300,000 miles maintaining tight responsive I6 and V6 engines. Transmissions had to rebuilt, but never the engines, and they were driven hard through the gears.

This is my first performance car with Nikasil cylinder coatings on Aluminum. I have heard horror stories about gas/oil effects on these coatings. Mostly about BMW's in storage. So I do treat the H4 with a little more tenderness that the "bullet proof" I6 and V6. I don't think it can hurt since my H4 works hard putting out more hp than stock.

Basically, turn it 3/4 to a full turn more just after the seal in the filter touches the metal part on the car. In my experience, it works out to be a heavy hand tightening.

I don't think pre-filling makes any difference. I am pretty sure, oil will come out from oil filter mount if you pour fresh oil without installing new oil filter.

i usually use oil flush before i drain out all the oil. after the oil is gone and i take out the old filter and clean the gasket it was connected to. fill the new filter with new oil and oil up the gasket again, pop the filter back in and fill up the oil tank.

Best thing said in this thread. This is more important than what type of oil you use, what type of filter you use, whether you prefill your filter or not, or whether you crank prior to starting. . .Just change it when ur supposed to.
