Not about the dollars, all about the numbers. Gotta get those MPG numbers up.

I'm driving a 2000 Insight with LTO conversion.

So Ethanol Free >> Ethanol for the MPG numbers, but which octane should I be buying? Some gas stations near me have 90 others have 87.

On my fuel log I track the gas type used. That's the 2020 log, you can find my older log (Pre-Lithium) in there as well.
