Synthetic oil bad in a lawnmower? Any truth in this self proclaimed experts statements?

[Gebo]

I noticed my Amsoil Small Engine oil is rated "SL".

Damm, what a load of BS. I have two Honda small engines one V-twin 20HP and one single 8HP, along with a generic lawnmower and a Yamaha golf cart. All these engines have used 15-50 M1, 15-40 diesel oil, M1 10-40HM and now M1 10-30. Some are 20 years old and never an oil related problem. All are small engines with no oil pump or filter except the 20HP Honda. They are happy with most any type of oil as long as it is clean and changed reguarly. Probably going to use 10-40 Supertec syn next, depending on availability.

Check The oil level before every start. Top off if necessary. The rest is what we argue about

Yea... no problem for me. Using it nearlt eliminated my oil consumption on an older techumseh gen set.

I use what ever on my regular 2 trash picked Toro "Personal Pace" mowers (which i love by the way). I have a ton of oil that was purchased in the 1980's. so I just run that. if it blows up, i have a nother spare mower engine but they run fine. I have a big yard and just dump the oil when it looks dirty and add another 7 oz. I rotate using them and when one breaks, I have the other one and never fil to cut the lawn.

Run rotella synthetic in my 9 hp diesel genset yanmar.

I've used just about every weight, and type of oil in my mowers. The oldest being a 1997 Craftsman. So being that's my story of use and abuse, when should I expect it to do it's impersonation of a Nuclear meltdown?.,,

Sounds like a nice generator. What’s the model number?
