Hi,
Would straight 50 be ok for an engine?
Or what would one recommend?

What sort of engine is it for?

Depends on the application.
If its for an enclosed engine with oil in a sump that gets hot it might be OK as it will thin with increased temp, however if its for drip fed bearings, it might be a bit thick (unless the engine is a big un).
The manual for my R-H 1HR - 6HP open crank with drip fed mains specifies straight SAE20.

Im not too sure how hot the crankcase gets as i havent ran it for more than a half hour at a time. Thanks for the replys so far .

Probably shouldn't, but I tend to chuck Wilkinsons 20W50 in just about everything four stroke!

My Crossley 1075 barely breaks into a sweat & only by keeping the pot covered can I get as high as 80oC .
I use modern cheap multigrades in old engine applications without a qualm - far better than the oils they were constructed to survive!
IMHO, SAE 50 will be too thick unless the engine is working hard on a summer's day.
