    If Possible, NEVA run the fuel that low unless U gotta drain and drop tank. Yer fuel pump is cooled by the fuel in the tank, and the return. If U run too low too often, U take the chance of helping along fuel pump failure. A lot of ED owners and Diesel owners sometimes do this also because of the fuel range, and such and the mentality. Too many PPL have trashed systems. Just a saying as yer ride, and do what works for U. All IMHO...........

    Question...Why would you even let it get that low? That just creates a better chance of sucking something bad off the bottom of the tank

    I think that's a myth. Fuel is always being sucked from the bottom of the tank.

    My 2019 1500 classic big horn the low fuel light comes on when the miles remaining hits 50. Every time so far it comes on when that hits 50 miles remaining. I don’t know how any gallons are still in there at that point but I figure it’s between 3 and 4.

    Doesn't the EVIC have a "Miles to Go" counter? My 14 2500 Tradesman's low fuel light came on (I don't recall where the counter was) and I drove it until it said it had 8 miles left in the tank and after filling it, I calculated about 1.5 gallons were still in the tank at that point.

    I try to never go below 1/4 of a tank on any vehicle so I just go by the fuel gauge and then fill it up. Seems to me that most vehicles tend to have about 3-4 gallons remaining when the light comes on. When my wife & I were dating in college, she had a mental level of V for vapor before she bought gas. :)

    On my 13 3.6,it varied. I keep the display set on economy and it tells you how many miles are left calculated from your mileage on the first part of the tank. If you slow down and drive easy you can double it. After driving in traffic for a week, I can hit the open road and watch the remaining range increase.

    You offer good advice, but I have say I have run my vehicles down to fumes more times than I can count, even to running out of gas several times, and I never once had to replace a fuel pump. I have been driving since 1979, BTW. Is it a bit of a risk for the fuel pump? Yes. Is it a very, very small risk? Yes.

    Seen my 17 mega cab gas show less than 15 miles to go. But only took 25 gals to fill and I know it has a 31 gal tank. With no more mpg than it gets it was probably right. LoL
