I use premium in all my small engines - lawn tractor, snowblower, boat motor, weed whacker, chainsaw. I'm pretty sure they don't require the octane of premium to run good, but premium is the only grade without ethanol in it.
The biggest problem with fuels with ethanol is they go "bad" after about a month and really gum motors up. Even fuel stabilizers don't stop the problem, though they may slow the process down some.
