Funny you should mention the "old fuel".... I got an email from Marty Davis yesterday on that very issue. He stated that he has in the past had fuel that had absorbed water and caused the boat he was setting up to run much slower than expected til he switch to a different jug. He said he was of the opinion now that he wont even puit unused fuel from the tank backl into his jugs - he just tosses it. So I guess it is worth replacing. If you'd like to read the email for yourself, PM me your email address and I'll forward it on to you.
