cmhj2000, Welcome to GasSavers. You're saving gas already but you will be doing better soon. Lots of good help around here. If you can, try slowing down a little and pump your tires to 45 psi. You will amaze yourself.
Enter your garage and gaslog info when you get time. Other members like to see whatcha got.
Welcome to GS! I have been waiting for a Vibe to join us because I am eager to see what a GasSaver can do in that drivetrain. There are a few of your sister "Matrices" in the garage, but it doesn't look like they have recent gaslogs.
Had a Moonstone 05 myself (loooong story) ,anyway you've got a good start . Get the pressure to max on the sidewall to start - 40's are *that* easy even with the auto . Start a Garage and gaslog entry and Definitely read up ! Welcome !!
