right-o. premium gas only. as for motor oil, people have told me to use mobil one synthetic. the preferred grade is sited in the manual (5w-30).

does anyone no the filter mesh size?

 

I use Mobil 1 5W-30 in the engine with a Subaru filter and new crush washer at each change. You should also look into the Redline 75W90 gear oils for the transmission (assuming manual) and rear diff at 10K or so (friction modifiers in the transmission, none in the diff).
