Lately when I have been driving with my windows down, I've noticed that a strong smell of gasoline. At first I thought it was just the other car next to me but when I drove past by my friend, he noticed that there was also a scent of gas. So it does seem that I might be burning more fuel. I checked my car for any leaks and there was none (although gasoline does evaporate in air). My MPG also hasn't gone down, it's about 18-20city and 25+highway. Any idea what could have cause this or anyways to solve it. Could it be the gremlins....could it????
