How accurate do you find the MPG gauge is? On the way to work this morning it said I averaged 21 MPG at 70 mph.

Have you guys found it to be accurate?

 

dont have it in my truck. i wish i had the overhead console, but i dont. i do it the old manual way.

fill up my truck, reset my trip odometer, drive...fill up my tank and take the miles driven/how many gallons used to fill the truck. i always fill it to the brim, so i always fill it to the same spot because i noticed the automatic stop seems to change at different gas stations

 

Over all I find it for averaging it very close to basic calculating. With in a few 10ths. I let it continue without resetting so I get the big picture.

 

When I filled up last night near my house the auto fill up thing at the station fill the tank all the way to the gas cap... guess thats one way of making sure I can go the farthest on a tank of gas

 

The MPG calculator isn't bad...sometimes it's dead on, but I hand calculate every tank and sometimes it's off by a mile or more. It's just hit or miss.

 

I've found mine is usually dead on. And if its not, always within a mile +/- what hand calculations say.

 

mine is very accurate. depending on my driving habits. i get between 380 -410 miles to a tank which is not bad.

 

Wow you get some good millage im lucky if i get 280 out a full tank

 

That sounds about right... its what i avg on a full tank with city and hwy driving mixed.

We must drive like old friggin men!

 

WOW I don't think I have ever gotten that out of my truck! I think the most was like around 330 and that was like one time!
