Ive been looking around and i see that echo and stihl have their own premixed gas in 32oz metal cans for sale at various places. If im not mistaken the cap is plastic and the container itself is steel. I was curious if it is possible to copy what stihl and echo are doing and just premix and pour some into the seafoam containers? I know it probably sounds a little iffy but i was just wondering if i might be able to contain premixed gasoline in the cans and use them as quick refills on the job instead of pulling out the big red can O' gas to refill my handhelds. thanks!
