Subaru engines never likes thin oils, a heavier oil was always good for them. A Euro spec 5W30 or A3/B4 0W40, 5W40, 10W40, 5W50, 10W50, 10W60 is all good for these.
Using spec Cafe oils sometimes results in the oil light flickering at idle, if you really want to run this oil the oil pump can be bumped up from a 10mm to an 11 or 12mm depending on the engine but to what end, just use a heavier oil. JM2C
