Have you tried our method of calculating MPGs instead of relying on your NAV?Jacko3 wrote:steve24:
I have no idea what is happeneing to the MPG of most G35X drivers. But I do know that on highway driving where I routinely flog my car up to 7000RPM in 2, 3, 4th gears, I have not gotten below 21MPG. On highway normal driving @ 70 - 80 miles per hour in 5th or 6th gear, I am getting an impressive 25 - 27 MPG. Sometimes, the gas needle doesn't even move---pretty impressive. Infiniti never told us that that the car could get better gas mileage than what was posted.
In city driving, when I flog the car routinely up to 7,000RPM, I experience a best of 17 MPG. Under normal city driving, I experience a best of 20 MPG. Of course, my car is moded out, and I use synthetic oil, so this maybe playing a role in the good gas mileage.
I think you answered the question yourself. You are able to shift into 6th gear with your manual, with the X, you are stuck at 3k rpms when cruising at 80mph which is a huge gas guzzler and needs to be revamped in upcoming models to maximize the overdrive gear.Jacko3 wrote:steve24:

We are also stuck at 3k RPMS in the manuals @80. The final gears for the AT and MT are very close in ratio.pits200 wrote:

The gearing on the X is not made for good gas mileage especially at highway speeds over 65mph.
IIRC, the break in period for the Gs is like 1500 miles and the two requirements are that you don't rev past 4k RPMs and you don't keep the engine at the same RPM for long durations (the engine needs to be sped up and slowed down).Goat_Wiz wrote:Just hit 2k, and I get about 24 mpg. I got 19 once, but I was racing a friend home from work. I do about 65% freeway. I drive long distances to work, but I use the G throughout the day to get around. Work in Seattle, the traffic is awful. Even when there is no traffic, the stopping and going is ridiculous. I don't 'break-in' my cars like most people though. I don't go WOT for 600 miles, but I also don't baby it. It worked for my '07 Civic Si (I know, not a very popular car here, but I love Hondas too) and my Mazda CX-9. I got better performance that most and the gas mileage in my CX-9 is great compared to others that I've read about. I routinely get 22-25 mpg in it. A friend of mine told me to break in cars this way, gradual acceleration to go fast and such. He is involved in racing, both track and off-road. I know our cars and engines are not like those of race cars, but the logic behind it made sense. He just explained that you should drive the car hard from the start, but with some finesse. Just just mindlessly flooring it and constant revving in nuetral. I did a lot of research on it online and the 'break in' is not how it use to be. Some still believe it is necessary to baby it from the start up to a certain mileage. There is also evidence that suggest being too gentle on the car can cause problems down the road. I can't think of the websites I read, but if you google it you will get a great deal of debate about the topic. There were a ton of results when I did it. It has worked for me, and seeing the numbers posted by some of the other G owners, makes me believe it all the more. He told me performance would be better, as well as fuel economy. SOrry my text is being really wierd when I post lately. The alignment is funky.
*had to edit, late here and my post didn't make much sense at first, hope its a little more clear now
To heck w/the environment, have you ever been in a car with straight pipes? OMGSentientbydesign wrote:Jacko,
Please don't get a test pipe. It's bad for the environment and tests have shown near no gains over a hi-flow cat.
