2013 Honda Accord - is synthetic oil necessary?

My wife’s 07 Lexus oil recommendation is 5w-30 (conventional or synthetic)…and my 14 Highland with the exact same engine oil recommendation is 0w-20. The reason - fuel economy…PERIOD. For t he past year I’ve actually been using 0w-30 in both vehicles.

You are committing a deliberate act of blasphemy!
Yet your car would most likely last the same as on recommended 0W20 or even longer
