Hi friends,

Possibly a dumb question (as I for some reason cannot fully wrap my head around the oil viscosity thingy), but my 2013 2.5 Prem CVT manual recommends 0W20 synthetic oil. If I was to use Mobil 1's 0W40 oil instead, would it do any harm, either in short run and/or over time?

I currently have only a few hundred miles on my 2013 OB, but plan on doing first new car oil/filter change around 1000 mile mark.

thanks,
plex

When your mother said NO, it was NO. Period. (I was a good boy)
So if Mother Subaru says that 0W20 is the best oil grade suited for your car, stick on 0W20 ! ;-)))
