Really don't matter to me. There was a big stinko on here about Tru-Fuel and from mu y personal experience, I never had issue one with it but then being a multiple Echo saw owner, IU prefer Red Armor, just a personal preference and nothing more. If I was running the saws daily or I was a professional arborist and using lots of fuel, I would be running e-gas. I'm not so I don't and 23 bucks a can ain't gonna bust my arse anyway. Besides, I repurpose the empty cans. I take a can opener and remove the tops and store welding rod in them, segregated by type and grade.
