2003 Toyota Matrix Block Heater

Its really hard to say. If I had to guess I'd say 2 mpg or less.

I'll be installing a block heater on the Paseo this fall yet. I'll try and do some testing when I get it on the car.

Do you have the Matrix block heater or did it go with the car?

I sold it with the car. I had the marinco plug on it. So, if I would have removed that there would have been a big hole in the bumper.

I added you ~2MPG estimation to the Wiki since we had no data. I listed it as an estimation.
