If it's calling for 30 weight, a 5w30 will be thinner than spec at all temperatures below 212, so it depends on the operating temp really.
Is there any Mobil One 10w30?
But yeah, sounds ok. I think they specify SAE30 oil because it's cheaper. SAE30 is pretty standard.

I don't think I've ever seen a sythetic oil in a straight weight....at least not in many years.
