It isn't new per say; E-15 aka Unleaded 88 is Regular Petrol with a higher blend of ethanol in it. I've attached links that will explain it better than I. https://ethanolrfa.org/retailers/e15/ https://ethanol.org/ethanol-essentials/facts-about-e15 https://unl88.com/ In short, if you have a newer vehicle, it is safe to use and can promote longer milage. However, if your fuel economy is poor, it will burn up quicker than regular ethanol-10, aka Regular Unleaded gas. Not for use for vehicles that need a minimum octane of 89 (Medium Grade and up), Flex-Fuel (Some are safe to use but if you have flex fuel, use E-85 instead), or older/special vehicles like lawn care or sport utility. (Which actually recommend E-0 or No Ethanol, to prevent damage to the interior of your motor.)
