I have a 99 r6 and ever since I've had it the fuel warning light is dim compared to the other lights in the cluster.Is this normal.Also ,how far can you go on reserve (miles).

usually you can go around 18 miles on reserver from what i have heard from ppl running out personally I havenn't ran it out of gas yet

I've gone 25 miles with the fuel light on and I put in only 4.04 gallons and that completely filled it up...
