Gas with 10% ethanol can ruin lawnmower engines.
The old sets of wheels gets the corn free.
I’ve ran it in the 16 Tacoma and saw no real difference.
What I do know is you better not let stale 10% ethanol gas stay in your lawnmower tank over winter or you will have to get the carburetor cleaned out in the spring. One of my lessons learned the hard way.
