my mileage dropped to only 33MPG when I switched to 95E10 gas (95 octane/10% ethanol).

my car seems to like 98e5 more (98 octane/5% octane). It's 6,4% more expensive, but consumes it way less.

The compression ratio is 9,8:1.

It seems that the engine management can take really good advantage of higher octane gas. How suprising.
