Replying to: 5_more (Feb 22, 2009 6:21 pm) I have a new 2009 mazda 5 sport auto trans. and I am getting overall approx. 25pmg (5 tankfuls so far). I live in northern ky and when I use the auto defrost the a/c always kicks in, so I turn it off (and it does get very cold here at times) so I have mentioned to my wife not to use the auto climate control whatsoever in the winter. Now the brakes were a bit touchy for my wife and I, but we adjusted as everyone does. I can't help but think if one gets 20mpg on the M5 then your probably safe to say that in the Sedona one would be averaging 3-4 mpg less as well? At any rate I would like to hear what comes about with this mystery...

Replying to: 5_more (Feb 22, 2009 6:14 pm) Correct...coasting vs pressing will save you the gas...but the action of pressing the brake does nothing to your MPG. E=0.5mv^2 The energy lost is heat from brakes plus the drag of the engine (unless you're in neutral). Indirectly you're correct, but again it's not the action of braking saving gas, but if your are or aren't light on the gas pedal. I think you're confusing being light on the gas pedal and coasting with the action of pressing the brake. The former will give you better MPG. You should gradually accelerate after a stop sign or red light to improve MPG too. You don't want to zip off the line and then coast to a stop and think you'll get better MPG...that won't happen.

Replying to: tomas_elantra (Feb 23, 2009 5:42 am) Your Mazda5 is getting 25MPG in Kentucky, and i'm getting 20.5 in my Mazda5 after 4 fill-ups. I live near Buffalo, so it's colder. But 4.5 MPG colder?? I'll find out Wednesday when i take it in. Hopefully I don't get a song and a dance. As for "5 More's" comments, your way past me in breaking this down. Thanks for your imput though. Here's how I drive: 1. Don't burn out when taking off from a stop. 2. Accelerate just enough so the guy behind me isn't all over me. 3. Don't tail-gate. 4. I usually go the speed limit, or 5 to 10 over, depending on traffic flow. 5. Try to get off the gas and coast some when approaching a stopping situation. As for the Sedona, I really wanted it  . I had a list of 5 values when I was shopping. MPG was on the list. An 8-10 MPG difference (assuming the Mazda5 would get 25MPG...HaHa) between the 2 cars resulted in me buying the Mazda. That 8-10 MPG difference adds up when the cost of gas shoots to $4 per gallon.

The source of that energy is in the gas tank. sbsteggs, To really make you mad... I've been getting better gas mileage in my Sienna than you're getting in your Mazda. My Sienna gas mileage is about 5 mpg lower than my Mazda 5, both in the city and on the highway.

Replying to: 5_more (Feb 23, 2009 4:15 pm)  . I kept my 1994 Lumina APV over my 2001 Venture because the Venture was an absolute piece of junk. It had a major list of problems. I had only always bought Chevy's, but that Venture ended it for me. So i buy this Mazda5 and seem to have an issue with it right away. So i'm not mad, just bummed and kinda laughing a little.

Replying to: sbsteggs (Feb 23, 2009 4:45 pm) * Cracking noise from the base of the windshield when it is cold * Body vibration at 50mph * Uneven tire wear -- the rear wheels sit like this / \ * Rear suspension noises when cold Motor mount and rear shock failures are also reported. Good thing you got rid of the Venture. Watch this: http://www.youtube.com/watch?v=HDQrPnAhSmI How's the rear main seal on the APV?

Replying to: 5_more (Feb 23, 2009 8:15 pm) The suspension seems really stiff and already creaks in the cold. And i can already see the back tires set like this "/ \". Like it's sut-up like a racecar. HMMMMMMMMM. Did i get a Mazda flavored Lemon?

Replying to: sbsteggs (Feb 23, 2009 11:26 pm) All I can add is that I do not let the vehicle warm up in the mornings, perhaps only about 30-45 seconds max, but that should not matter regardless. This morning as I write this it is 18 degrees out, and I would bet you are not that much colder there. If what you mention in the above comments is correct then clearly something is definitely not functioning as it should on your Mazda, and I hope the dealership can fix this for you. Could you have received bad fuel somewhere? This is a LONG shot but I wonder if the oil is ok ~ possibly somehow it is contaminated or lost it's viscosity in someway? The same would apply for the transmission fluid? I realize that this is FAR out there for possible explanations.
