I have been flying using mogas extensively for over 10 years. My LAA aircraft was one of the first to be cleared for use with E5 mogas (ethanol). I transport up to 3 X 20L cans in the boot. I would never use a leaky can and I use a purpose made siphoning tube. No issues, no problems, big cost saving. My alternative would be a 40 min round trip with a £14 landing fee to fill up with Avgas 91UL at about a 1/3 more per L. One word of warning, mogas in the UK is a very different product to the US.
