just wondering, not planning, but what non vw spec oil could i get away with if i found myself unable to change oil at a vw dealership on a 2.5 liter, 5 cylinder? my 86k mile 2013 passat s runs fine. i'm faithful to the 10k mile oci at a local, decent vw dealership. but, i like to take extended road trips and if i were to find myself over 10k miles in the middle of nowhere needing a "tide me over" non dealer, more generic oil change, what is collective wisdom? i understand the cautions about vw spec but what more common, i.e. non vw or non euro spec, oils would be ok for say 3k miles in this simple, non turbo, robust engine. not looking to cheap out but wouldn't want to dump an expensive boutique synthetic oil at 3k miles either when i next got to a dealer, if this makes sense. thanks all!
