I know there is a differenct in AWD vs FWD but what about if you get the towing package? We just bough a new 2008 CX-9 GT two days ago with a towing package to tow our sportbikes up to the mountains and to do track days. We haven't filled up the tank yet so I have no idea what mileage we are getting yet. But the towing package does include a special ECU program. Just wondering what the they do the computer and if it affects gas mileage?

People realize the tank has at least 2.5 gallons left when the light comes on. This is the key in calculating MPG.

Replying to: cx7lover (Jul 07, 2008 9:36 am) What the mpg calculator (either on the car or the one in your head) should be figuring is how many miles you drove on the number of gallons you used. So, if you drove 200 miles since your last fill up and you filled up today and put ten gallons in, you got 20 mpg no matter if there were 2 or 5 gallons left in your gas tank when you pulled into the service station.

You will see some variation with the click-off method when measuring MPG. However, if you do it over a long period of time, it is acurate.

Hi, All: I have installed a ScanGaugeII on my CX9 for about 1000 miles now. I am here to report my findings. I used the ScanGauge as the trip computer that is missing on our CX9 (the 2009 model shall have it!) On my CX9 GT AWD (loaded with accessories and options - saved DVD entertainment system), I found that - it is easy to get 22 mpg with CX9 on highway. On my trip to Sacramento (a bit hilly on some portion of the roads), at 70-75 mph I was able to get 22 mpg w/o much effort. - it is no so easy to get 15mpg on city that full of lights and stop signs. Unless you can time lights perfectly and acceleration so gently (to the extent that does not piss off your fellow drivers), it would be hard to get 15mpg on this heavy CX9 with short 1st gear (4.15 ratio). With some try and error, I am able to do it now with help of ScanGauge to show me the instant MPG. The idle easy kills the MPG you tried so hard to improve. A red light auto-shutdown and start (like in hybrids) would be nice. I did try to drive it like what I did to my BMW, I consistently get 10-12mpg on city street. This what a heavy vehicle with short 1st gear can do to your MPG. It revs hard to get you off line (zoom-zoom). Overall, since my commute is a mix of city and highway, I was getting around 16mpg. With the help of ScanGauge (to change my driving habits), I am consistently getting around 17mpg. As I said, there is not much you need to do on highway other than maintaining constant speed (at whatever you desire). The trick is to be gentle and smart on city streets. Of course, what I found is not ground breaking. It is all common sense, really. However, if you are getting 13mpg now, you should know what is wrong now.... P.S. I have K&N filer in my airbox. I will change it back to OE filter and see what happen to the MPG.

Replying to: ceric (Aug 04, 2008 3:31 pm) I have been contemplating purchasing a Scan Gauge II for our CX-9 since it does not have a mileage computer (ridiculous on a $30,000 + vehicle!). Would you say it is worth the money? We recently moved from OH to Eastern PA and even going through the mountains at an average speed of 65 - 70, we averaged close to 26 MPG! We were in SHOCK! Anyway, just wanted to let you know if you do drive with a conscientious effort, it is possible to get noticeably better mileage (~18/19 in city, 24-26 highway). Please let me know about the Scan Gauge. |
