2015 Subaru Legacy Fuel Gauge Problem
I let the tank get low enough for the low fuel warning light to come on. I filled the car and the fuel gauge light is still on and the gauge hasn't moved. Is the sender bad or just stuck? If it's stuck is there an additive I could add to the fuel and free it up? Removing the tank and replacing the sender does not sound like fun Frown

Find a steep hill. Drive up. Drive down. Drive on a side hill.

No, there is no additive to add. All additives that you can purchase are essentially carrier fluid and a few parts per million of antioxidants or detergents.

Good idea, I'll give that a shot. Thanks.

That worked, now my life is good. Thanks again.

Did you try pulling the negative cable off the battery for 5 minutes to reset the computor?

Your backup plan is called an odometer.
