Use Mobil-1 in everything except motorcycles. Motorcycles use Amsoil synthetic.
Have a riding lawnmower that is 22 years old and been using Mobil-1 10w-30 since the break-in. Runs great - no leaks - uses no oil - Briggs & Stratton Twin cylinder. This lawn mower has seen many hours over the years.
I have no issues with synthetic.
My neighbor who grew up with a father and mother that owned a small engine repair business and has worked on many small engines runs synthetic oil in everything, including using Stihl 2 cycle synthetic oil in mixed gas.
