What's the most you got out of a tank

Ran into a small issue of forgetting my wallet at home and gas light coming on, on my way home from work today. Only thing I could do was pray that I made it back. I was honestly really impressed that I was able to get 360miles out of one tank. I do about 85% highway driving. 2014 JKU auto 3.21 with KO2 mud terrains

I average 350 to 360 regularly now but when I first bought it I couldn't get it past 320. The Jeep has just under 10k miles now.

Getting to 350 was my magic number because it means I only have to gas up once a week, but to be honest, even when I was only getting 320 I wasn't all that upset. I love commuting in my Jeep.

Dang I wish I get that much on a regular basis. Then again my Jeep is going on 60k. And mileage dropped once I put the leveling kit and mud terrain tires on.

This is commonly known as the hidden 5 gallons. When the light comes on there is 4-5 gallons left on a 4 door, 3-4 on a 2 door.

The thought behind this is due to a carry over fix on the TJ's where there was a problem with the fuel sensor accuracy, where TJ owners were running out of gas before the light came on.

I get 350-360 on a tank (JKU) routinely. 3.5" lift and 35" K02s.

When my Jeep was still stock I was getting close to 400 miles averaging around 22 mpg. JKU, 3.21, 6spd. My commute was 37 miles each way all highway with some traffic thrown in. Now with the 285/70 Nittos and the 2" lift I'm averaging 19mpg and about 330 miles, but I never wait until the light comes on. If I'm around a 1/4 tank and see a cheap station I stop. Commute now is 27 miles mostly highway, but a bit more traffic.

Let it be known I also drive like a grandma...

I'm at 240 miles on this tank, normally have to fill up at 225, but a trip to the lake last weekend for a bachelor party helped. It was about an hour and a half each way, for the first time ever, I saw 20mpg average.
I'd be happy if I hit 275. My drive is usually stop and go city traffic, so not any competition for a Prius, unless there's 18" of snow on the road.

Ok, question for you....

The other day, I was driving, and I actually drove to the lowest point on the Fuel Gauge that I've ever been in any vehicle I drive. I was practically on E once I got into the gas station. Cluster was giving me the "Lo Fuel" indicator and all.

I proceed to fill up, and I barely got over 15 gallons into the tank (even topped off a little).

I'm fully aware that they add a small reserve for stranded situations, and I even was just perusing my build sheet, which tells me I have an 18.6 gallon tank.

Is it possible the reserve is about 3 gallons?

I'm not complaining, I guess I'm more astonished that I have that much reserve space. I don't normally drive until I'm on E, maybe 1/4 left is when I start getting anxious...

I almost always fill up when I hit a 1/4 tank, though I have been known to do so around 1/2. I've never encountered the need to push my luck with low fuel, too many gas stations are passed and the credit card is always handy.

Stock JKRHR with 3.73 auto. I usually get ~225 or so before I fill up. My son went joy riding a couple of weeks ago and got 290.8, the fuel light came on and he panicked (I was not happy).
