The dealer said like E65...1 step above regular but on the internet it says you can use regular....can I use regular gas in this car & if so why would the dealer say to use the higher gas?????

Us the regular kind. E65 is an alternative fuel for chevy with flex fuel. Unless your car says flex fuel use regular fuel.
