On a side note, does anyone know why our cars get so many rock chips???

I do not think I get much better than 25 MPG, but I can't seem to keep it at the limit, so I do not know the real potential.

kidkotic2001 · 05-17-2011, 09:08 AM

I get between 30 to 32 MPG when I am not driving fast.

I love how much mileage we get out of our Z's. Hell, I get better mileage than my damn rental, a Chevy Cobalt.... that is shame.... SMH.

You're telling me. My 3300lbs IS300 with the 215hp I6 only averages 20mpg. 18 city and somewhere around 22-23 highway. Yet your 3250lbs 370Z with its 332HP motor does better? Jesus.....

I just did a 100 mile trip all highway and the computer said 17.6 for MPG. I was crusing at around 70 the whole time. Right under 3k RPM's. This is a bit concerning because it's not anywhere near the 26 mpg it's suppose to be getting on highway. Why is it so low??

I am correcting my previous post a bit. I used cruise control exactly twice -- just to see what the optimum mileage would be. I am more in econ's world as I tend to drive the pizz out of my Z's.

Don't know. I get around 23-25mpg at Interstate speeds. 70-77mph. Low tire pressure can cut the mileage by 2mpg. It has for my car. I just checked my TP and they were low. Around 29psi. Supposed to be set to 35psi. My mpg drops, I check the tire pressure.

I have never seen 26mpg. I don't really care though. I just fill up and enjoy the ride.

26 mpg on trip computer at 75 mph steady.

Here's hoping once I get more miles on my Z the numbers improve. (only 1400 miles now)
I'm not seeing anywhere near the mileage of some of you guys are saying you're getting, and I'm running a larger Imperial gallon in my calculations. (5/4th a US gallon)
It is my understanding (from Nissan ratings) they'll get about 33 mpg tops on an Imp. gallon. That's about 26-ish on a US gallon, HWY mileage.
Forget what the computer says.....compare the fuel used against the mileage driven.

I haven't been all that concerned with the mileage I've been seeing so far because I expect it to improve with a little more miles on the clock, but I'm averaging about 22 mixed driving right now, per Imperial gallon. That's in the teens on a US gallon.
And FYI, in the past I 've always been able to get better mileage than the manufacturer's numbers on anything I've driven or owned, so it's not my right foot. When I say 22, that's nursing it. Dreadful mileage IMO.
Thankfully I buy gas in the US.

I just don't believe the 30+ claims unless it's a 5-10 mile trip t 60-70 behind other cars or trucks. I had the 2010 base coupe that got me a max, on just one trip of 200+ at 26.7 mpg, most other normal highway trips, I would get 24.5 mpg.

On my 2013 Sports package with 19 in., wheels, the best I could do was 23.8. At fast speeds of 80+, it's between 21 and 22.

cossie1600 · 11-23-2014, 08:55 PM

I did 27-28 @ 75mph with cruise

mayday813 · 11-23-2014, 09:51 PM

Drove 1,431 miles and averaged mpg 26.7 using calculated mileage not the computer. Mostly interstate driving speeds running about 75 mph. A/C on a good portion of the way. In town 19 to 22 mpg depending on traffic. 40,000 miles on the vehicle. Six speed models have a 3.69 ratio rear end IMO the gas mileage is pretty good considering 332 hp.

Zipper 104 · 11-24-2014, 12:56 AM

That's more like it.
If guys are realistically pulling around 26 mpg or thereabouts on US gallons, it puts Nissan's numbers about right at 32, 33-ish for an Imperial gallon. That was a number I figured I was able to live with before I bought my 370.
Now I just have to do all my driving in the U.S.
