Gas tank needle goes up while driving...why?
I notice that from the time I start the car to after I am driving for a few minutes, the gas needle goes up about 1/8 of a tank. Is this normal? Whats the correct reading?

this is just a shot in the dark but... if you have any varrnish buildup on the sending unit, it can cause an increased resistance, after driving, the slosh wears off the varnish and you have an accurate reading again.
again, this is just a guess
again, this is just a guess

The reason that your needle is doing that is probably from the floater inside the tank. It might not be able to fully read the gas level when the car is first started. Try changing the floater unit if it really becomes a problem because I had a friend whose car went from empty to full and back to empty. Hope that helps

My car does the same thing as well. I really wouldn't worry about it a lot. The gas gauge actually fluctuates naturally under normal driving. Anyway, we can go so far with the light on Id say worry about it at that point.
