The question is being glossed over IMHO. Assuming the unleaded gas is 10% ethanol combined, with a newer design engine and with likely two years plus of fuel onboard there is no upside.
Sure, I remember the good old days when gasoline was used as a diesel thinner for old or wrong season diesel fuel. Been there done that. That was yesterday's fuel and old engines. The OP has options. One is to listen to those of us who have no skin in the game, another is to assume risk with fingers crossed or lastly give the fuel away.
With the Canadian border closed, storing onboard and consuming the fuel over multi years of Puget Sound cruising seems an unattractive option.
