My Honda uses 5w-20 in the crankcase and 10w-40 in the transmission. It's like water. The VTEC doesn't work right without it.

216's were supposed to use SAE20 oil, I wonder how well 5w-20 would work in one?

I suspect other than a bit of extra lifter noise and slightly low oil pressure a 235 will be fine. The main bearings are so big they probably will be fine. You may burn or leak more of it though.
