I've got a 96 GL with 259k on it. I recently put 56 dollars in it (13.5 gallons) and the fuel gauge stated that it was full. I drove 365 miles on it between a good mix of city and highway driving. 60 of those miles were driven with the fuel light on. I was trying to run it completely out of gas but decided to fill up before that happened because I heard that could damage your fuel pump. Is that about as good as I can expect for a vulcan? I feel as if I could of gotten 20-30 more miles on it but I wasn't so sure.
