Just checking out this site looking for ideas on how to spend less $$$ on my 110 mile a day commute. Yes I have a very good reason for that ridiculous commute but don't wish to discuss that now. I drive a 2006 Mazda 3 & went from 27 to around 31 MPG changing my driving habits, speed mostly. I have always maintained my vehicles so thats not an issue. Now that I am outta ideas, I am turning to the ever scary internet for people I don't know to throw out ideas that could kill me. I think I'll go with the tire pressure increase first & go from there. I have heard about increasing pressure a while ago but thought it would cause blow outs. I'll start here & feel free to give me ideas or whatever you wanta say.
