i mixed up some drews brew last night. i was all disappointed because i was only getting like .3 mpgs better. but today i reset the over head and drove around town a little but and took a few short runs on the highway. now the over head is reading anywhere between 16.9 and 19.6. hopefully it stays this way.

quick question on the over head. is it more accurate if you reset it everytime you fill up? or just dont reset it at all?

 

Mine seems to be more accurate (if you can call it that)when I leave it alone. The closest it's been is within 1.2 MPG of actual. Mine reads higher than it should.

 

mine normally reads higher than what the overhead says too. ill check it out. as long as i get the illusion that im getting good mpg's ill be happy
