Poll: Which gasoline gives you more mileage? Pls share your experiences. Thanks.

I go with the gas stations which give me rebates on my card that i use.

Same with me, rather than hunting for a gas station with cheaper price, or a gas brand that can give me better mileage. I just go for the gasoline that can give me 3% rebate. That's already 1.50 savings per liter.
