3 mts and my fuel gauge was on empty?? Yes, but don't remember exactly and when dealing with the newer trucks of today I have no idea since mine was 20 gallons.

I'm pretty sure of 2 things by now:

1 - the fuel gauge is purposely designed to show your tanks as emptier than they really are, and

2 - those tanks hold slightly less than 100 gallons (you can't fill them to the tippy-top anyway because of the location of the hole)

Next time your tanks are low, take a flashlight and look in there to see where the level really is.

Yes, you have a reserve of about 15-20 gallons. The fuel Guage won't read all the way to the bottom of the tanks but in all honesty, you never want to run them that low to begin with. You run a greater chance of picking up whatever crap has been settled on the bottom of the tanks by running it all down, ruining the fuel filters and possibly causing fuel starvation in the motor (if you've ever had to prime a diesel engine after running it dry, it's a lesson you'll never want to repeat). Plus, this time of year, you never know what you might run into weather or traffic wise and running that low just isn't a good idea.

First off, the tanks do draw off the bottom but running them low does not make it pick up more stuff. It is going to pick it up no matter what level the tank is. Your fuel is constantly sloshing around and stirring things up anyhow. Someone had a bad experience one time and it was convenient to blame it on low fuel levels. Bunch of hog wash if you ask me.

I forgot to get fuel one day. I was 40 miles into a 90 mile trip and the red light came on... Well I made it the last 50 miles. There was no where to stop to fuel anyhow so I figured the further I make it the less I have to walk. Turns out the truck holds about 170 gallons and I put 164 in the tanks. Not going to do that again... LOL

I've got a 2015 Kenworth too. The fuel gauge definitely makes it look emptier than it is. I’ve found that there’s about a 15-20 gallon reserve. I wouldn’t rely on it too much, though. Running low can stir up junk from the bottom of the tanks, which can mess up your filters. Better to plan stops a bit earlier if you can. I learned that the hard way once!

Keep a wood yard stick in your compartments to check the level of fuel in the tanks. I would mark the yard stick when it was full and then you can make a good guess at the amount of fuel in the tank. You can't always trust the gauge to be accurate.

I get nervous when my Frightliner gauge hits the red zone, but it has gotten down to just above empty several times. It also has two 100 gal. tanks. The most I’ve ever put in was 145 gallons. I think all the manufacturers design in a so called reserve amount to protect drivers from themselves. And also to keep from sucking up from the very bottom. A road service call because of running out of fuel would be very embarrassing.
