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.
