I asked this qyestion on a different forum, but theres more Candians on here. Is the Husky Premium the stuff one wants to use? I fill up at Shell, Esso 91 but noticed Husky has some Higher Stuff. Did have some Pre Igniton happenning but think I have it covered but still curious? My 340 has 10 1/2:1 so need to keep good fuel in it. Thanks D
