You are in the Infiniti G35 Forum. Your Hosts are pat & karens
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

I know for sure that on my '07X that it is "required" so a) I don't feel I have a choice and b) I want all the performance I can get out of that sweet engine. It is nice, isn't it. P.S. It is still going to be a few weeks before I can report on MPG since the estimate for repair is 3-4 weeks and 16-17K. Ouch.

Replying to: durangojay (Sep 02, 2008 10:08 am) Also, thank you for sharing the crash scenario with us. A lot of us assume all cars are created equal with regard to crash safety, or we give that aspect little weight when selecting the car. Can you share what brand and size tires you have, as well as the tread remaining? Hydroplaning in real world driving is a fact of life; and many of us who opt out of Summer tires when it is time for replacement are in the hunt for an acceptable compromise, willing to give up some dry pavement grip for an increase in better inclement weather performance. I started another thread on winter tires since 30,000 miles my OE Michelin PS Summer tires are cooked, and in New England we get snow. Main Topic: INFINITY G35 COUPE Subtopic: G35 Coupe in the snow. . This winter I can't just garage the car and will have to use the G Coupe as a daily winter driver for the first time. I would appreciate it if you and others would share your winter driving impressions, especially those that have switched to either an all season tire or a dedicated set of winter tires. Again. Glad you are intact and that the car can be repaired. Jack |

I don't want to deviate too far from the thread here, but to my recollection the tire were Goodyear Eagles. OEM on the car when I purchased it. Yes, it was frontal and yes I'm going to have the system checked before I take it back. I have also called Infiniti to register a complaint. It should have deployed. If I need to replace any tires, which I don't know yet, I'm definitely going to go with some that are geared towards wet/snow weather, since I run them year round. Perhaps my MPG will actually go up...j/k. Thanks for your well wishes. I'm sure she will be good as new when repairs are finished. Jay
