^^ Still pretty funny that he didn't have an answer after the OP posted his MPG with Regular vs Premium.

 

Same engine yes, but tuned differently. Manual says you can "Temporarily" use 87 fuel but only put in a little and replace it with Premium ASAP for 6mt drivers.



If you want to use 87 fuel go ahead. It's your car.

But for an extra 10cents per gallon, I'll go with premium. That's what? An extra $1.80 per fill to go premium. LOL

 

premium is about 30 cents more a gallon in texas

but we do get 93 oct
