Ok I searched and found many different threads and answers but most where for cars with mods. Ok so I have 03 Wrx 100k miles on it I don't beat the crap out of it but do drive it like it was meant to from time to time. Can anybody help out and tell me what's the best oil brand and weight for a older stock Rex I'm gonna go to dealer to get stock plugs for it and I was thinking mobil1 gear but now I see something about non syn. for the rear. Is this true? I'm between homes rite now just moved to palmdale from norcal so my search is being done from my phone so any help would be great really great! Thanks guys and FYI subys ain't that big here yet so I get looks when I wave lol! TIA Miguel
PS oil size and type for front and rear please oh maybe how much if that's ok also thank u
