I just filled up 2 days ago and Im only getting 188 miles to the tank according to my gauge....I do have a exhaust manifold leak but even with that I was getting 330city/400hwy....car has 79k

 

thats damn good gas mileage!
driving the new hybrid Z?

 

I use cruise control a lot lol and everyone says I drive like a grandpa...

 

I can easily see 400 miles to a full tank of gas.

 

Just maintain the vehicle once you get it.... run cleaner fuel through it (Shell Brand, Chevron w/Techron). Never run cheap stuff and check out the vehicle's maintenance... Transmission service, Radiator, Rear Diff, etc.... Something I did to mine that showed to help a lot was a 2-stage Fuel System Cleaning. I also run full synthetic motor oil (which I did since I got the car at 20k miles) and it seems to help the motor stay smooth.

Nissan says they build their cars to run at least 200k miles... but you still gotta maintain em.

 

Yup, typically i only get 380 on average, but have also seen 500 freeway driving.

 

I had a 310k mile 1992 celica and it ran at the track exactly what is was "suppose" to run 16.9 stock
I turbo'ed a 2001 kia sephia at 150k miles and still was at full compression 15.2 at 4psi...
My 350z with 140k miles ran a 13.6 which I think is in "spec"

It all depends on how the car was maintained.

If it feels sluggish, usually a fuel filter replacement and a full tank of gas with lucas injector cleaner works well.

 

yessir!
