i didn't think it was that worthy of question for field testing. i was just bored and couldn't come up with an answer. I knew it wouldn't affect MPG in any significant manor either way because you are probably only coasting like that for >1% of the time you spend driving. but thnx anyways for going out there and getting the cold hard facts!
plus running 555's i don't even want to think about my MPG i pretend gas is free everytime i fill up (helps me sleep at night)
*****Disclaimer - My spelling is horrific! i appologise in advance :)******
