Mezzo hit on the bigger issue here with the ethanol content permitted in today's fuel. Ethanol has very different burn properties and is also hydroscopic.
Super u/l does have less ethanol indeed some have no ethanol so best research the fuel specs from your supplier.
The ethanol content creates no problems for modern petrol cars using closed loop injection systems monitored by an exhaust lambda sensor but it will have a huge effect on a 2 stroke using carb.
