they can run on regular fuel but not optimally. The GXP performs pretty badly with regular. With premium it drives quite a bit better. My shortstar also only 'requires' 87 but it performs quite a bit better with 89+I'm curious if that'* why the GXP drives so bad in comparisons between it and the SSEi. If dealers are only putting in the 87 octane because that'* all they 'require' that'd make a big difference on your driving impression..
