i had my mpg up to 32.5 mpg

got in my car , started it up and the mpg display started to go nuts going down and down, up a little then finally ended on this :

but yet my fuel range says this

anybody have any idea why it would do this. or has this happen to anybody else? no i didnt reset the display either.
thanks for the help!

 

how recently did you reset it, and how long was it idling for? idling kills your mileage. you are getting ZERO mpg while idling. and that will totally bring it down

 

bend a long time since i ve reset it-maybe around a year- this happen as soon i started the car and was getting ready to back up.

 

you can not reset the tank mileage calculator. When u reset the mpg estimator it just resets the mpg. When u get on the highway to go a long distance u will see the the miles in tank remaining will go up or stay in the same spot for the first 30 min to 1 hr of driving

 

what are you referring to?

 

I believe stonny is referring to the distance until empty aka, "fuel range"........ that cannot be reset or anything... the fuel economy can however....... and if you want to feel special, reset the economy while going down a really big hill.......... yea 99.9 MPG

 

I was told if you reset it, don't do it in neutral. If you are in neutral, yet moving aka, coasting, it'll go nuts. I got mine up over 75mpg before I put it in gear and reset again.

 

Weird....

 

lol or do the opposite and reset it while peeling out.

 

im gettin 360 to a tank....unhook the battery and let it do a relearn....youl get better gas milage maybe..i was gettin like 300 to a tank and i started gettin 7-11 gas and did that battery thingy and now i get like 360...lol its sounds like bs but im tellin you...i dunno wtf is going on....i know the car adjusts fule range and whatnot according to yoour driving curve...thats where the relearn helps
