I am a little biased since I am an Amsoil dealer. I run synthetic in everything I own.
Amsoil makes an oil called "Formula 4 Stroke" that is designed for small engine use. It is an SAE 30 that meets the 10w spec due to its full synthetic base stock which doesn't thicken in cold weather as much as conventional.
I have run it for going on 10 years in my small engines with great results.
I like a synthetic for small engines since they run so hot.
