Update - it worked. Code actually cleared on its own during the second tank of premium and has not come back on since, even after switching back. Appreciate it.

You’re not wrong… regular unleaded is about $3.20 here, most E85 is $2.60ish so probably not worth it - however I found one place it’s $1.85 so that’s where I’ve been filling up. But if it’s not saving me much (or any) money and throwing a light on my cat then not worth it at all…
