Fuel Gauge

On our last trip I ran my fuel gauge down to 1/4 tank (first time ever that low). The low fuel light came on and the gauge started to swing between 1/4 and E. At times it dropped to empty and stayed there for several seconds then bounced back up to 1/4, (smooth road, no up or downs). Luckily I was close to a small town and filled in $20 (about 15 liters, enough to get me home). The gauge stabilized at just above 1/4 and stayed there till I got home (30 miles). At home I fueled up and was able to add 396 liters (105 us gals). This would suggest that I still had 45 gallons of fuel in the tank. Does anyone know at what level the low fuel light is supposed to come on? I am ok with it coming on at 1/4 but the fluctuating fuel gauge at that point had me worried that I might be running on fumes.

Usually the fuel light come on about 1/8th tank. But each coach is a little different. You should be able to easily burn 130 gallons (assuming you have a 150 gallon tank). As you drive you will learn how your fuel gauge tracks your fuel level.

On our coach 1/4 tank requires 105 gallons to fill.

I have a 150 gallon tank. My light regularly comes on at 1/4 on the gauge, something over 700 on the odometer, and takes from 100 to 115 gallons, depending on how much gen time I've had on this tank. So, all this means that 1/4 on my gauge is actually 1/3 in reality. But I almost never go there, because the generator also loses fuel at that point.

When I picked up our new coach from the dealer and drove the 100 miles home, I noticed the light coming on a few miles from home.... I was not happy that the dealer gave me the coach with so little fuel and I was mad that I hadn't caught it when I was inspecting the coach... anyway, I stopped and filled it up, it took 120 gallons, so at least on ours, the light comes on when there is about 30 gallons left .
When ours is at about 1/4 mark, it takes 100 gallons

So the low fuel light on at 1/4 tank is not out of the ordinary. The fluctuating gauge may just be due to sloshing of the fuel in the tank, but why would it only start once the light comes on?

Hi jarwiebe,
Over the life of a coach the times the fuel gets to 1/4 tank or below is rare for the vast number of coaches. The mechanicals involved to move the fuel gage and trip the light rarely get the chance to be exercised. My fuel gage, below 1/2 tank is more of a play toy than a gage.

I reset the trip odometer at each fill up. I know my coach and the MPG I can expect. For me, scheduling a fuel stop every 500 miles or so always works.

+1! I know with my tank and MPG I can get 1000 miles if I push it hard and find a fuel stop. But I start thinking at about 500, and somewhere between there and 700 I'm at the pump.

I hadn't reset my trip meter at my last fill up but I figure I had between 700 and 800 miles when my low fuel light came on. That makes sense that I would still have about 50 gallons "on reserve". 100 gallons at 7.5 MPG towing my Liberty gets me my 750 miles.

Over 40,000 miles our average is 7.05 mpg ignoring the gen usage. I start looking for fuel when the gauge reaches 3/8's. Usually end up taking 75 to 100 gallons, depending on how far I travel to find a station.
