I’ve decided to test my fuel tank warning light, as I’ve never let my tank get down below 1/4. Just would like to know my distance I can safely go on a fill up. And where I am on the tank when at E.
My 88 XJS Coupe says it’s capacity is 25 U.S. gallons. I assume that’s 24 tank, and 1 gallon surge tank.
So I am going with a 24 gallon capacity. I’ve been reliably getting 12 mpg, so that means about 288 miles to empty. Right now, I’m sitting a hair above E, and the odometer reads 244 miles. The light has not come on yet. FYI, about 1 1/2 years ago I put in new tank and new fuel level sender. I also do not have the trip computer anymore.
Most of my other cars, the light comes on when there are 2 gallons left.
I’m starting to think of the Seinfeld episode…and see how far I get? I may purchase a gallon of gasoline and keep it in the car with me!
Any details of your own experiences would be welcome.
