I run my generator twice a year. About 15 minutes in June when we fuel it up for hurricane season and for about an hour when we put away in November after hurricane season. We keep the jerry cans all fueled up during hurricane season and then one or two small ones in the off season for emergencies.
We can pull fuel from the fuel rail with an adapter and hose and use the Tech-2 to command the fuel pump to maximum output and fill up the jerry cans if necessary.
The mower, edger, chainsaw, generator and trucks all get fed 93 octane gas. Owner's manuals say it's ok and preferred for the small engines.
We use Wavian 20 and 10 liter cans, made in same factory taken over by the Germans in WW2. The flexible spout empties a can in seconds, not days like those Obama spouts.
