I'm using redline high performance oil (75/90 GL5)
At the moment,seems good to me.
Anybody else use different or better oil in a new age Impreza?
 
Any idea what it's called Nic? Is it just 75/90 or what?
Are you using motul engine oil too,what viscosity?
I'm using mobil 15/50 at the moment.
Also what plugs are you using,pfr7b plugs?
 
I put Millers 75W90 fully synth into mine. I dont know what was in it before, but the gearchange is lighter & quicker now than it was before the oil change :thumbsup:
