| 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

Replying to: KarenS (Jun 16, 2005 9:26 am) My averages over 1659 miles and 5 fill ups: Based on the computer - 20.3 MPG 31.7 MPH Based on mileage, computer time, and gallons bought - 20.2 MPG 28.8 MPH Given the EPA combined estimate of 19 MPG, I can't complain.

Karen, I think those are GREAT numbers, given how you say you drive. I wish my number where as high as that! I'll be interested in what your numbers are on a long highway trip. My bet is 24-25 MPG, which would be great. BTW, I think the gas you are using is some of the best out there, from my experience. Unfortunately we not have any Shell stations in my small town. Thanks for the info. Jay

Replying to: paulo6 (Sep 22, 2008 8:48 am) Yes, I'm happy with the computer accuracy, paulo6. I've never had a car that was within 0.1 MPG of my calculation. I just noticed that I had a 15 hour error on my first fill up (duh!). My earlier 28.8 MPH was wrong. It should have been 31.7 MPH. Come to think about it, that number is meaningless, as it is based on the computer's mileage and average speed. It should always match the computer (duh!). I have noticed that if I top off the tank, the MPH will be a tad bit lower than the computer on an individual fill up. If I simply stop when the station pump cuts off, the MPG has been accurate to within 0.1 MPG. I suspect that this means the computer bases it's calculations on the useful capacity of the tank (actual volume minus the space needed by the fuel to keep the fuel pump submerged minus the remaining volume when the station pump cuts off).
