If it still has good oil-control (doesn't leak or burn much), I'd go
for one of the higher-vi synthetics. Makes for a "happy" engine, IMHO.

I will double on that. I switched to 5W30 Mobil 1 on all my air cooled
engines. It can stand heat a lot better than conventional oils. Don't
worry about the 5 rating. That is only when very cold. When warm it
still has 30 weight viscosity and is a bit easier to start.

I have a 45 year old B&S engine that runs like new using it.
