Methanol is commonly sold as "octane booster". It's definitely around.

Is it in common use as such? Meaning 92 octane is 88 buffered with methanol? If it’s just in those little octane booster bottles, I would not consider that a “substantial additive“ in the context of the trillion dollar petroleum industry.

Around here it is used (in solution!) as ballast in tractor tires.
