Hi, guys I just purchased CX-7 (Touring FWD with moonroof and bose, XM radio Wheel lock Splash guard and all weather mats) I think I got kinda good deal (23K) 5000$ less than M.S.R.P The reason why I choose CX-7 is good gas millage. yeah I know it sounds like wrong but it has good gas millage. How do I know before I got the CX-7? According to consumerguis's real world fuel-Economy Champions in midsize SUV category u can easily find CX-7 in second place. not to mention that without hybrid it's first place!!!!!!!!! It's 2times better than worst champion in midsize SUV category here's link http://consumerguideauto.howstuffworks.com/consumer-guides-real-world-fuel-econo- my-champions-cga.htm I used to think to buy CR-V but since honda doesn't wanna give rebate to the customer. I changed my mind to buy CX-7 because It's bigger, stylish, fast and handling champion. (not to mention EPA Champion) before the reason why I didn't consider CX-7 is MPG but as soon as problem is solved I purchased CX-7. I didnt get it but I can't wait!!!!! |

Replying to: oldarmy (Nov 02, 2007 9:56 am) Have not had problems, I just went on a 1200 mile trip for a week, and I was doing about 70 miles average and my fuel consumption on highway was 22 MPG. I tested premium gas on the first 2 weeks I own the car and I felt the smell of raw gas several times, i contacted the delaership and they were upset at me for using premium gas. Had something to do with the engine management system and the the software. dmele72406  nyc.rr.com

| Purchased in Feb 08. 2500+ miles. Houston, TX area. Used consecutive tanks of 93 Octane and consecutive tanks of 89 Octane (R+M). Up to 10% Ethanol so Octane rating may actually be higher than stated. Overall averaging 22.16 MPG using spreadsheet. Low of 21.5 MPG and high of 22.99 MPG. Top up tank and stop on first click. 70/30 hwy/city. Does anyone have a scanguage ii to determine best economy/speed/gear on CX-7? Thanks | |

Replying to: dmele426 (Apr 29, 2008 9:17 am) Your computer has probably pulled boost, reduced timing advance, and added fuel enrichment in "self-defense" to keep from pinging..reducing power and economy. Now that it's broken in, I'd put premium back in it, it might take a tank or so worth of driving to "re-adapt" the stored table values up to where they should be. |

Replying to: outbackeddy (Sep 07, 2007 3:51 pm) with 8,000 miles. The Total miles for the whole trip from SW Louisiana up to Northern AR. was 1835 miles. Total amount of gas used: 82.8 gallons over all gas milage for the trip was: 22.16mpg $3.93 per gallon average cost per gallon of gas. We experienced a low of 18.59mpg in town up in the Ozarks. We experienced 26.36mpg, 26.41mpg and 25.9mpg on trip back home with mostly interstate and about 254 miles of two lane. Our speed was from 55-60mph on two lane. Interstate speed was 69-72mph with cruise control. Since my dealer changed the computer chip in the engine, it goes into 6th grear much easier. Passing 50-70mph is great, almost fantastic. It was a lot of fun to drive the CX-7 for 11.5 hours with several stops. We had two adults and lots and lots of stuff packed into the back with both seats down. I did mix tanks of Premium with 89 octane and had no problems with drop in power or gas milage. Going up to AR we experienced 21-23mpg. In town driving in the mountains was 18.59mpg on one tank and 19.71mpg on the second tank. Going home was more down hill with beautiful weather and gas milage was over 26mpg on two tanks and 25.9mpg on the last tank.

I purchased Cat in December of 2007 with 9000 miles on her. I'm up to 15000 now. During the winter (I'm in MN) I was averaging 15 MPG. This was due to extreme cold, lots of snow (hence lots of AWD use) and never warming the car up (a lot of city driving). Over the last couple of months, I've gotten around 19 MPG. Again, a lot of city driving and short trips. I have found that Kwik Trip and Shell premium provided the best results. I have used a tank or two of 89, it depends on the price. I am setting out on a trip to Florida (have finally regained my senses and will be returning to my birth state) so am interested to see what 2000 miles of interstate will do. I expect a jump in mileage once I arrive in Florida due to warmer weather and the retripping of the computer from the highway driving. I have always kept my RPMs to 2000 to 2200 on the highway unless passing. This varies the speed of the vehicle between 60 and 75. A lot of people think it's the speed that matters, but RPMs seem to make a bigger difference. I used to own a Hybrid Escape so learned a lot of hypermiling techniques that I have transferred to the CX-7. The only thing I really miss about the hybrid is the CVT which allowed one to put the transmission in neutral when coasting down a hill, which allowed for a much longer coast. |
