Wow! Vastly different experiences here. I have never filtered my Coleman fuel, never bought new each year -- just replace that gallon rectangular can each time it gets low.
And I have never had a stove clog even once, and have never had a flare-up, or a slow-down for any reason other than pressure depletion.
I DO check out the stove before I head out, though, lighting it up and testing it for leaks (rubber O-ring cracked once). I oil the pump once in a while, too. ...but that is all.
