Hey guys, so i just bought a 2004 rx8 with 80,000kms on it 2 days ago. ive only had it for 3 days now and ive noticed it has extremely bad gas mileage. Ive read a lot of posts on here that people are getting around 320-400 kms on a full tank, but ive already driven 67 kms and the tank is half empty :S im very concerned about this because ive been driving it really easy, and i bought it from a mazda dealer which said the car was in perfect condition :S . Is there anything you guys can think of that i should look into?

please dont tell me i should have researched the rx8 more before i bought it because i did, but right now the mileage ive been getting is absolutely terrible .

anyways cheers guys
