Thanks for the imput. I understand that those figure changes. My driving is mostly city, dont have a heavy foot and no driving with no jack rabbit start. On your edge you get about 300 mles on a full tank and and when your almost empty how many miles have you driven? is it close to miles you started with? I don't get even close. like i mention i had 370 on full and now im on empty tolal used miles is 198. thats a difference of 172. Is that normal??????? I've been keeping a close watch on the gauge... driving about 2 blocks and the gauge changes and will continue to change every 2-3 blocks instead of a miles or 8 blocks, so example driving my son to school is only 3 miles from my home it will calculate i drove 10-15 miles i dont believe thats normal.
