On my drive to IAG yesterday to get my taillight overlays installed I have finally surpassed 1k miles on my 2013 WRX. I have searched around for a while on here about what oil and filter to use and have decided on a few.
I plan on using Rotella T6 5w40. Would I have any warranty problems with this down the road? My manual says to use 5w30.
Or should I just use Motul 5w30? Although expensive, meets the required 5w30.
I'm still debating on which filter to use. The OEM blue? Or Purolator PL14460, PL14610, or PL14612? Again would I have warranty problems if I use the larger Purolator filters?
