Mobil 1 Oil Filter

[JDrex]

Anybody out there using a Mobil1 Oil Filter?
Mobil does not include the wrx on their application charts.
Some post show that an M-104 will work, but I'm wondering if
the filter might be too long and be a risk for high heat?

I have a monsterous commute of 200 miles a week, I'm running
Mobil1 oil with oem filters. The commute is all highway so there is not much strain on the engine, I'm alomost always below 3K on the tach. I plan on using a 7500 mile shedule for changes. If the oil looks OK I might go 10K. Keep in mind here that 10K is 10 weeks for me.

The M-104 is a Honda filter. I used an Honda oil filter that I had left over from my old Honda days when I did my first oil change. The M-104 will fit fine, but the only problem is that the top plate of Honda filters are concave, where as Subaru filters are flat. You can only get about 3-4 turns before it is seated.

I currently use Purolator PremiumPLUS oil filters.

The Mobil 1 filters are pretty good - but not $10 good! See this:

Save your money and get a Purolator PureOne or Wix filter. Just as good for half the price!

BTW, the PureOne WRX and Civic filter are identical except for the fact the Civic filter has an anti-drainback valve that the WRX doesn't need because the filter is mounted upside-down. It doesn't hurt though so I buy the Civic filters by the dozen for my car and my wife's!
