Which should I use to clean up the fuel system? I feel that my mileage is a little low(avg. 23 mpg) and I am sure that the system has never been cleaned. I do not have too much smoke emissions, other than when I nail it to smoke out a tailgater, which I enjoy. I like the idea of lubricating the system for maintenance. Thanks for all replies.
