Ethanol is a poor substitute to MTBE.. Unless there's another additive they use I think most use Ethanol to replace MTBE.. -- PotIsYourFriend ------------------------------------------------------------------------ PotIsYourFriend's Profile: http://www.automotiveforums.com/vbul...?userid=189569 View this thread: http://www.automotiveforums.com/vbul...d.php?t=669345 http://www.automotiveforums.com |

Gas mileage varies with brand of gas?
Two possible answers; ethanol may give you worse mpg than straight
gasoline. This isn't true for all cars & driving conditions. Some fuel pumps give you more than 1 gallon for every gallon of fuel you pay for. Best I've seen is +6 tablespoons (about 2 ounces) based on the state's measure of proper fuel delivery. Of course, some fuel pumps don't give you the amount of gas you paid for- worst I've seen is -2 tablespoons. If your state requires this rating, you might experiment and keep track of mpg based on the rating.
