Do "SF" rated oil have any special requirements I need for a Kayo S-200?

Hi, I'm going to do some basic maintenance on a Kayo S-200 SxS. I read the service manual, which mentions using "SF 10w-40" oil.

I had not heard of "SF" oil before so I searched. The first result is to the site BobIstheOil Guy.

There was some back-and-forth about what SF actually meant. I think it is an old classification and not used any more.

But, it seemed like MAYBE "SF" had higher Zinc requirements (ZDDP)?

I was planning to use some normal automotive Full Synthetic 10w-40 oil for the Kayo S-200. But perhaps I should get some Rotella TD full synthetic? I have used Rotella a long time for my diesel car/truck. I already have Rotella 15w-40 at my house I could use.

I think this might not even be a big deal, but with these low-power, older-technology engines, I don't want to assume standard synthetic is what they need.

Thanks!
