My understanding is that premium fuels have a higher octane rating than E10 91o Octane or 95 octane in premium is rated at 98 Octane. The RON ( octane number ) is important and ties in to the compression ratio of the engine - higher compression ratios requires premium fuels to prevent pinging or a lack of synchronicity between the explosion of the fuel in the cylinder and the stroke of the piston. In short most engines these days can run quite well on E10 which has only a 91 octane rating and no issues regarding pinging. Pinging will eventually destroy vital engine components and ruin the engine - make sure you use the right octane rated fuel for the vehicle otherwise you will eventually destroy the engine
