Does anyone work at a Subaru Dealer and know what Engine Oil they use? I've asked mine twice, and got 2 different answers .
They said it's Castrol, but weren't sure what type. I assumed Magnatec, but one post on this forum said Edge.
Weight is most likely 5W30. They said that when I called them last week, but the first time I asked they said 15W30 (which isn't even a grade that the Manual suggests, so I doubt that).
Reason is that I'm getting my Oil analysed. I run E85 and have some mods, so I want to know if my oil changes are frequent enough and if the oil is holding up. And they need to know exactly what oil was used.
I'll probably just do the oil changes myself from now on. But when I was still running 98, getting it done at the dealer (at half the normal engine oil change intervals) was ok.
