Before my low fuel light quit working, it would come on around 105 miles. So now this is how I gauge my fuel mileage; after filling up, I reset my trip meter to zero. At 30 miles, it’s about 3/4s of a tank. At 60 miles, 1/2. At 90 miles, 1/4 tank. At 100 miles, it’s time to start looking for a gas station. At 120 miles, I’m running on fumes. The farthest distance I have covered from a full tank was 130 miles. When I filled up right after, it took 4.1 gallons of gas.
