In my 2008 350Z, the fuel mileage computer was dead accurate to within 2/10 of a mpg. Is the Frontier the same way?

My 2006 VW Jetta TDi, is usually 4-5 mpg off ( optimistic)

Thanks!

Mine's fairly accurate. It's off about 0.5mpg lower than what I'm actually getting.

Not to thread jack here, but I guess I will anyway. Does anyone know if you can activate the trip computer functions on a cluster that did not originally come with them? Is it something that can simply be "turned on" or did it have to originally have it for it to work?

Some members have tried replacing clusters and found that it can't be turn on. It's part of the bcm or whatever controls the cluster.

So what modles did it come on? only nismo and LE modles? Is it possible that I have it and don't know it? Like is it under a menu from the odometer reset, or is it have its own screen and all?

i bet..

i had a 2007 mazda3 that didnt have the trip computer activated, and after searching thru forums, i found a guy who had worked at mazda. a few magical presses of radio buttons and ignition turns later, and voila! i had the trip computer.. i really hope that someone will find this to be true here also..

I found that mine was off a little when I reset it everytime I refueled. If I let it go for quite a few refills it seems to be pretty accurate.

And how exactly was the radio tied into your gas tank? Cause that just seems a bit like a tall tale to me.

the stereo in my mazda3 had a display with more info than just whats on the radio... outside/inside temp etc.. the only thing that was different was a name on a button. i could see the mpg in the background, and thats how i knew my display was capable.. its not a tall tale... look it up for yourself.

Fair enough. Sorry for doubting. I apologize.

While it might be possible in some vehicles, I believe this and getting fog lights to work separate from lights or parking lights has been researched and found to be not possible without major hurdles (usually BCM issues).

On mine, the trip computer is generally off. It doesn't seem to recover very well, especially the DTE function. It acts like it has a mind all its own. I can avg about 20-21 mpg on the highway, and the DTE will still only read about 340. Likewise, if I have a bunch of city driving that drops it down to the 16ish range and then go on a highway jaunt, it might only come up to about 17.5 while true calculating shows it in the 20.x range. So for me, it is fairly inaccurate.
