All above is good info….

…..ethanol free fuel will have lower octane.

Like someone posted above, fill with 87 and nothing bad will happen.

The knock sensor will prevent knock.

You’re not driving the damn thing anyway, so why worry about losing a few horsepower?

Just fill up with 87 “Pure Gas”, drop some fuel stabilizer or the PEA additives I listed above, and get on with your life.
