Gas cans suck, I just measure the saw tank and put the right amount of oil in and fill right at the gas station. Heh
Had a bad deal once when a larger can tipped over while driving.
I've ruined my forearms running saws and lifting wood I only use 1 or 2 gallon cans max that dont tip in the truck and don't kill me to lift if I don't absolutely have to.
A truck without a rubber bed liner keeps things like 5 gallon cans from sliding around, however, because they don't slide, they tend to tip over. The hard plastic drop in liners are so hard a bucket will slide but not generally turn over. Same with no liner, buckets slide around but don't generally turn over.
I try to always tie the can to a hook with a rope so it stays where I put it.
Plastic cans seem to be more puncture proof the steel cans are, depending on how thick the steel is.
Plastic breathes allowing the fuel to evaporate over time and sun light is bad for gas. Steel eliminates any sunlight from getting in keeping it fresher longer.
I only mix one gallon at a time so I have a better chance of using all of it before it goes bad.
But now that I have found a e-free fuel, I may take my 100 gallon aluminum fuel tank down and fill it up.
When I bought my generators I bought 2 100 gallon fuel tanks so I could store fuel for hurricane season, but that was before they started adding ethanol.
I think I can safely store e-free fuel a good six months in my 100 gallon aluminum tank with no problem, and I can always run it in my truck if I think it's been sitting for awhile and I just need to use it or loose it.
Fill a 5 gallon plastic can full of fuel and seal it tight and store it in the dark and leave it for about a month or two. The can will only be about half full.
