| I've been averaging around 24.4 MPG on my new G35x mainly on highway, using cruise control at 60 MPH. It's slow but i am trying to break in the car slowly and to improve MPG. When driving in city, i am using the sequential sport shift more often. I wonder if that would improve the MPG versus using automatic? | |

In my opinion, using the SS will help with your mpg, IF you shift quickly to higher gears. I believe this has been stated on this thread earlier. However, an argument can be made for "why bother". You could just drive in the city in regular drive mode and let the car do the work for you. Personally I like stirring the pot myself. It's more fun and it keeps you involved in the driving experience. I think your highway mpg is pretty good compared to what I get - 23.3. But I drive at higher speeds than that and use my manual shifting for the drive. I'll bet that if I used drive mode and cruise control ALL the time, I could squeak out a bit more out of each gallon. By the way, if you don't mind me asking, what did you pay for your new model? Do you have the Sports Package on it? Nav? I paid $37,250 for mine almost exactly a year ago in Denver, no Sports Package, no Nav., custom SIRIUS sat. radio (better than XM imo). Plus they paid for my flight from Durango to denver and cab fare to the dealership. I thought it was a fair deal. Safe driving...Jay

2004  29K miles. Auto. None of us bought this car for fuel mileage, driving in snow, or hauling a lot of passengers and stuff. Nor did we expect it to be among the fastest on the road. Dollar for dollar, this car does a lot of things exceptionally well. And day in and day out it is pleasantly functional for what it is. Slap on some Blizzaks and it can be driven year round, albeit with a serious degree of conservative driving. One poster said it best when he suggested taking an uninterupted highway trip over 100 miles, stick it on cruise at the speed limit, and then report back. His point was simply this. The car can achieve reasonable if not surprisingly good highway fuel mileage.....altitude/grade, low temperatures, and ethanol content notwithstanding. If you can't coax a highway 26 MPG out of this car, you need not look any further than your right foot and driving habits. Those of us who report 27-28 MPG highway are not pulling your leg. Last month on a vacation to the White mountains of NH, my wife and I got a round trip highway average of 27. My SIL and daughter followed us with 2 passengers and luggage in his Nissan Quest, and he got 25! He was amazed and finally had to admit that THE MILEAGE PROBLEM WAS HIM! Fooling around on the mountain twisties, brief blasts to 120, and simply enjoying the car while "there," was a different story. Sure, I got 13 mpg, easy. And it sure was fun doing it. 21 mpg in mixed conservative driving is normal for me. Pure around town mpg with traffic makes 18 mpg a moral victory. Stop worrying about the fuel mileage and start enjoying what you paid $39K for. Jack |

I think you're right, Jack. Ease off a bit and watch it creep up. Thanks, Jay |

I should mentiom that I did, indeed, buy mine to drive through the snow. I live at about 6600ft above sea level in Colorado. I can attest to two things: The X drives great in the snow w/o snow tires (although a set of Blizzaks wouldn't hurt) and two, that my mpg in inclement weather doesn't flucuate much from normal driving. Great car...can't wait to get it back from the body shop. All clean and shiny and new....

| I have to say that so far I'm fairly happy with the MPG on my new G35x. I'm averaging 21.4 MPG over the first 600+ miles on my G. What I do realize is that I'm still in the break in period and I haven't applied the lead foot yet (well at least not like I will after the break in period). I'm sure the MPG will drop some once that happens. I had been averaging around .5 to 1 MPG higher on my 2003 G35 that I traded in for my new 08 G35x. So, not that much of a difference really. | |

Replying to: sweendogy (Sep 13, 2008 5:10 pm) Someone else commented on their G's gas tank capacity 16 gallons !?! The 04 Coupe is rated at 20 gallons. I put in as much as 18.5 gallons a couple of times (miles to empty read --- or 0). But I stopped running the tank down when another poster noted that the fuel pump depends on fuel to remain cooler during operation. My wife is back to driving the car daily (mostly highway), so I am happy to report that the fuel mileage plummeted back to 21 mpg from the pure 26+ highway I previously reported from our vacation last month. The lower fuel mileage she gets is worth the price because I can tease her about her lead right foot. Her response is: "I paid for the horsepower and I am going to use it, all of it!" Enjoy, Jack
