How Low Can You Go without fueling?

im sure the taste of diesel is still better than the coffee at TA

 

On my 13 cascadia when the low fuel light comes on I have about 20 gallons left in each 100 gallon tank and better be getting fuel very soon.

 

I ain’t very brave, I’ve never let mine go below 1/4… why? The man who owned my truck before me @Diesel Dave told me not to do it… lolol so I don’t…

 

I put on twin 120s and i still havent gone more than 177 gallons between fills.

95% of 240 is 228, i assume i need 15 gallons each side to not suck air, so call it 200 gallons absolute max
I average high 5, low 6, seasonably variable, so assuming 5 mpg its 1000 miles max for me period. (Ive done 1100 a few times)

Ive had to pay for a guy to fill my passenger side 20 gallons before when i was in the middle of chicago, rush hour traffic standstill. I refuse to be there again and i dont trust crossovers to not lie to me.

 

1100 miles, maybe more. Depends on my weight. 220 gallons is about the most. Twin 140 tanks.

 

I have a gauge for each tank .. I'am like @staceydude .. I don't let my tanks get below a 1/4.. But I also have certain places I like to fuel so I base my fuel stops off of that premise

 

Yeah, that sucks. I carry a cheap Harbor Freight manual transfer pump specifically for nonsense like that.

 

My fuel gauge has never worked. I was having issues where one tank would drain faster than the other that screwed me a couple times. I've fixed that but I still never go anymore than 1200 miles without filing up. I have dual 150s and keep them as full as possible always.

 

My tanks capacity is 250 gal. My fuel gauge used to show I was empty after burning 200 gallons but after replacing the fuel level sensor with a longer stick, it got more accurate.

 

The most I've put in with 300 gallons was right around 235-240 don't remember. A guy my uncle works with ran out of fuel literally a mile from the loves in Kirkwood NY and had a service truck bring out some fuel and when he goes to pull out side swipes the service truck Lol. Talk about a bad day
