gas tank size
 

how big is the gas tank on the RX8 i cant find it online and the manual is at home

15.9 US gallons.

:(
it only costs me $14 to fill up the civic.. this tank is bigger then how much i usually spend then if i put premium $30 for a tank wow thats gonna be a suprise at the first fill up

tell me about it

I don't think fuel costs will be a problem for me. Right now it costs over 40 dollars a fill up for my truck. Granted I have a large tank, but I am only getting around 17 mpg. So when I purchase my 8, fuel economy will go up, but so will gas prices (normal to premium.) Therefore, my miles per dollar will probably stay about the same.
