1995 Buick LeSabre Owner's Manual - Page 111

Here are some concerns ownershave had about the fuel gage. All these situations are normal and indicate nothing wrong with the fuel gage. 0 Low Fuel Light (Option) If your Buick has this option, a yellow light near the fuel gage will come on when you are low on fuel. You should get more fuel as soon as you can. At the gas station, the gas pump shutsoff before the gage reads F (full). It takes more (or less) gas to fill up than the gage indicated. For example,the gage may have indicated 1/2 full, but it took more (or less) than half of the tank's capacity to fill it. The gage moves a little when you turn a corner, speed up, or stop your vehicle. When you turn the engine off, the gage doesn't go all the way back to empty. 0 0 0 2-55
