I know I hear all over that using higher octane gas does not really make a difference in economy. Anyone have any thoughts on this??? I know here in Canada, where a block heater is not an option when you buy a vehicle - it comes standard; a lot of gas stations here have what they call "winter gas" where they all have their own secret recipe. I know when that "winter gas" comes out my mileage drops and I start looking at the little 4 bangers until I wake up and realize that I couldn't do half the stuff I do with my van.
