Dude this is a BOARD it is ment to talk about stuff if i want to POST that he is full of **** and i do not think he was able to get 58MPG in his Aveo then i have the Right to do so. Now i have driven accross the country. 28 states i have been to. i also have been in 2 other countrys. Mexico and Canada. I know that 55 is not the Speed limit in all the states. here in CA it's 65 and some roads it's 70. but Trucks and trailers have a 55 MPH Speed Limit. AZ has a 75MPH Limit. I think Utah does too. so what is the Speed limit for the area you got the so called 58MPG? i think that all of the Numbers for this So called 58MPG should be posted i think you should post Milage, Fuel, Speed Limit, Google Maps the area so we all can se it. i am willing to recreate what you did to see for my self that it can or can't be done. as much info that you have to get the 58MPG is needed so start making a List.Originally Posted by ontarian_frog
