Personally I will drain my tank bone dry like last year and start fresh next year. Worked last year and will do again this year. I dump the whole 50 gal. tank out into containers and use in snowblower and lawn mower, it is easily accessible. I put a new Racor filter in this spring and add Startron every fill up and have had no problems. God I hope I did not jinx myself now.
