I have a 2011 toyota corolla that i bought brand new 3 weeks ago and the sale sticker says its 26mpg city and 34mpg hwy but when i fill it up it feels the same as my 2007 toyota tundra thats 16mpg city and 24 hwy so to me it feels like my corolla is bad in gas in doesnt last very long, is there something wrong with it? Also my brother has a v6 3.5 dodge charger 2007 and it seemed great on gas when i drove it up to the beach but my corolla doesnt seem very good on gas, please help, thanks!
