Helo all , I've seen many post on the forum about : I have a xx gal tank but I run it to the fuel low light and I can only put in xx galons ?

Well , I decided to test the accuracy of my ( miles remaining ) counter .

My low light first illuminated with 59 miles remaining in tank . I continued to drive Untill it was at a Range of 20 miles then filled it up .
I feel like it was pretty accurate .
I have a 26 gal tank .

Trip A was this tank of gas , odd how the math doesn't add up ? If you do the math , total miles divided by the avg mpg , this would've taken 28 gals ? Wierd....maybe I filled up all the way nursing it in to the filler port last time I gassed up ? Not sure . I typically get over 500 miles on a tank , but I've never ran it down this far before.

I've never reset this avg mpg page for the life of the truck , and I don't plan on ever resetting it .

This is pretty accurate for me having a 26 gal tank , pretty happy with this little experiment .

Ah nice I literally just got a 2015 Dodge Ram 1500 5.7 v8 two days ago, black with the blackout package. Excited to make new Friends and find ideas on here to do some stuff :)

WOW , been a while ....
I completely forgot about this thread I created .

FWIW , I've found the low fuel Lt & miles till empty are pretty accurate for my truck ..

Too funny, ten month old post about fuel and ironheadmuscle caught the CEL.....

BTW.

I have the 32 gallon tank and my first fill up was when the light came on with sixty miles left on range but I was only able to put in 26. This next tank I ran it until it said 19 miles range and was able to only get 27.7 in, these trucks are really erring on the side of not letting anyone run out of gas. At my last fill up my EVIC said 18.6 and actual was 17.3 (7% off) which is not too bad, Hyundai is horribly over rated when it comes to their computer which was off as much as 18% in my Santa Fe.

I will probably let it run down farther when it is not so stinking hot out, but in Florida I gotta have that remote start to cool it down. I love that it automatically turns on the seat coolers too......

Yes , I was surprised to see anyone post in this thread ....;however, my avg mpg per the evic is off by approximately 1ea mpg ... not accurate , but now that I am aware of this I'm also aware that my miles remaining is about 1ea Gallon off as well , which actually ends up to be approximately .5 gals ....so not terribly bad IMO .
