It varies from one silverado to the next. Take a can full of gas with you, then let the truck run out of gas and see how far you went after the light came on.
Around 3 gallons.
about 2 gallons, or around 30 miles left
GM designed the low fuel light to come on with an average of 6 gallons of fuel left. However, in reality it is generally between 2 and 4 gallons.
30 miles
approx, 2 gallons. enough to get to the nearest station.
what does it mean if my brake light is blinking on and off when its pushed down in my 1999 Chevy silverado
Enough to travel about 20 miles.
a 2003 Chevy silverado taillight bulb uses a 3157
Maybe 1 to 1 1/2 gallons but don't count on it.
It is on because the ECU has detected a problem with the emissions system.
If you mean a low fuel light, then NO.
It should if it is the round body style such as 2001 or 2002.
