5w-30 is fine, so you're Ok. Even the link
he provided lists Pennzoil and Valvoline 5w-30 as having an LL-01 rating, so it's just as within spec as the Mobil 0w-40.
There are others available these days that qualify as well, but I can't find the link I'd seen from another board. If I find it, I'll share it.
