Anyone have a cyclonic Briggs and what weight of oil are you running in it

I bought a John Deere 535 m with a 25 hp cyclonic briggs and the owners manual recomends every weight under the sun. I’m a 10w30 hd guy anyone got any real hours on one of these engines.?

I have one on my Husky ZT. I have used 10w30 in it which is what was recommended for the engine. First oil change at 10 hours. I have 150 hours on it now and no issues to date (3 years old). I change the oil and filter each year also which is what is recommended.
