Before I forget thanks for the video. Good start for my morning!
My '07 low fuel light always came on at "50 miles to empty" on the compute. Every time. Hit reset and it would go out for 5-ish miles and then back on. Truck took 23 gallons of fuel at that point. On a daily driver there was always fresh fuel in the system, even in winter, and I saw the warning from time to time.
On my '17 the low fuel light comes on at maybe 25 miles and not consistently. I rarely run it that low though.
I normally use the left display on my Type 3 dashboard to show digital speed or miles to empty when towing. The tachometer is jewelry.
