Been thinking latley about getting a can of coleman lantern fuel and seeing if there i any difference in performance from the pump gas i've been getting.

Premix, at least over here, guarentee's a 5 year usability in unopened condition. So I would never fear after one year.

Further I never dump, the lawnmower/tractor, etc. love the rests of my mix batch. And I have no problems whatsoever with mix 1 year old.

Non ethanol + Bel-Ray H1-R. Let it sit in a non vented container as long as you like.
