Gas Mileage
Hi Guys,
First of all, I have read several threads regarding the poor gas mileage from some of the G35 coupe owners, and I already know that this car was never intended to be a fuel efficient vehicle, but the fuel consumption that I am seeing is much higher than what other people are seeing including those who have already complained. Now, I know the fuel economy given by Infiniti is probably the most efficient (ideal case) I'll ever see , but the numbers should more or less be in the same ballpark if you're driving conseratively. At first, I thought it was my heavy foot so I figured it would consume a lot less gas if I drove more conseratively so I tested it by doing a round trip 100km in total and all were highway kms. I drove as conserative as I could to see what the fuel economy would be and it still took almost 1/3 of my tank of gas! Even some of the G35 owners that I know who do 50/50 city and highway kms still get around 500kms to a tank, but Im seeing 350km to a tank with 80% city and 20% highway. I think I should still be hitting somewhere around 400kms to a tank. Does anyone know of any defects that may be attributed to an increase in fuel consumption?

Really though, the gas milage in my car is great on the highway. I drove to DC and on the PA turnpike was getting around 32mpg. In the city I avg. 20-22mpg

infiniti = nissan -> nissan is made in japan-> japanese use metric system -> metric system in japan -> japan makes nissan -> nissan = infiniti -> infiniti will work better with metric system
Been getting poor milage lately cause I have been having a heavy right foot lately. Even then I was already experiencing poor milage. Been getting less than 350 miles for a full tank of gas. I use to get 400 miles a tank.

gas mileage really depends on the driver, if granny smith drives the car, she'll prob get a lot better mileage than a true car enthusiast who is willing to take the car near redline, and go on high speed burns. I know it's hard, but drive your car easy and you'll notice a higher fuel efficency. A lead foot burns lots of gas.

I can get from 17mpg to 21mpg... depending how fast I'm driving.

For reference my G averages between 20-22 mpg with 75/25% city/highway. On straight highway running about 110-120 km I get 30 mpg. (Canadian gallons) On a complete full tank to completely dry these work out to 538-593kms/tank city and 810kms/tank highway however I would have to allow at least 75 kms safety margin so as not to run out.
