370Z highway mileage?
 

What sort of mileage are you guys seeing on the highway?

at the right speed and gear with no traffic i can hold it somewhere between 30-35 mpg

If I set it on cruise and reset the MPGometer...

60 MPH = 38 MPG
70 MPH = 32 MPG

I was surprised it was this high, but I've tested it multiple times and get similar results each time.

That is sick!

Wow that's very good for a six cylinder.

from the day i picked it up new till now which is 63000 i get 22.1. thats highway, some city mileage. on a good day i can squeeze out about 410-420 miles per tank but thats rare since its fun to go fast and that makes gas go quick.

I averaged 30.5 mpg from Chicago to Omaha (right around 450 miles) in the Z once, doing around 75 most of the way.

(Which I was quite impressed with!!)

Thanks boss.

I get 28-30 on the highway

Hmmmmm i only see 24ish around 75..... Only has 3500 miles on it tho

Several trips to Dallas / San Antonio / Austin from Houston and average 30.2 MPH @ 75+ MPH.

Ya I drove 100 miles doing about 55 mph and it said I was getting 36 mpg. I wasn't doing constant speed or elevation, so I don't doubt being able to get 38 mpg at 60 mph. Be careful doing this though, cuz I almost died of boredom.

if you can stay off the throttle you'll get better gas mileage... but its just too fun

mid 30s with normal driving

mid 30's averaging 60to70....
overall average is much lower than i care to guess

geez you guys must be driving some freak cars. best i can get is 26mpg when im cruising on the highway @60mph. however, i almost always cruise around 75mph...

What octane are you using?

Ditto. Just drove ~600 miles today from Toronto to Boston. Mostly cruising around 75 mph with 93 octane. Got about 25 mpg. All tires running 35 psi cold, no passenger, light luggage.

Official Nissan specs are 18/26 mpg. I call BS on 30+ claims - you'd think Nissan would boast with those figures if the car could pull them off.

34 MPG in the perfect world of a Turnpike trip with no air conditioning and cruise control. 20.6 MPG, consistently, in the real world of mostly sensible suburban driving with a little fun, every now and then. No complaints. More than fair for a beautiful, fast sports car.

Your right we are all lying or the computer is

91 or better..we only have 91 in california, but there are some places that sell 100 unleaded :icon17:

seriously though...with mixed city driving i get 19. if i do ALOT of highway ill see something in the 22-25mpg range. ive never even seen the instantaneous gauge sit at 30mpg+ when cruising

Your not all lying. Many things affect your gas mileage. I just think some of you don't understand it.

28-30 can be achieved on a warm sunny day and your traveling long distance on a flat road with out many hills.

Short 30 minute trip not so flat roads all highway your gonna see 24-25.

I my self have achieved 29mpg highway with ease on a nice road mostly flat and cruise control at 65. Reality is though expect to get 24-25 because its the most consistent baseline I get in my driving.

Things that I think affect your MPG
Heat level affects tire PSI then affects MPG.
Hills on the road affect MPG
The highway your traveling is uphill verses down hill.
Rain, non rain.

That's what I figured. I think 93 would be a bit better but not as much as what's showing up. I appreciate your response. What do you think of San Diego? Thinking of moving over that way.

I'd agree with those variables. Thanks for that response dude. Type of gas as well as brand or octane I think could be another. Reminds me wish I had Chevron in my area.

how is everyone calculating the mileage? using the in car MPGometer? or trip meter/gallons at fill up?

Did a long road trip to the Virginia mountains last year, I got about 26 to 27mpg average on the highway. This at an average (and relatively constant) speed in the high 70's and measured over a full tank. The scangauge indicated an instant 35+ mpg every now and then, but that was at (much) lower speeds and perfectly flat or downhill bits... I really wonder how people get 30+ mpg average on a full tank. 45mph constant on a perfectly flat road and tailwind maybe?

No, just drafting behind a semi gets me 30+ mpg.

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

and california is beautiful! id love to move to SD one day

because you're drafting behind a semi...thats 18 wheels of rock chipping goodness :stirthepot:

dont draft if you dont want rock chips. even with my full clear bra i stay far, far away from any big cars

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

:icon18:

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.

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.

The best I get -- with cruise control set at 70 - 75 -- is 27 mpg. I think some of this result is caused by the 91 octane in CA. This is the highest you can get at the pump.

Also, the computer, as many have pointed out, is only an estimate. The only true way to determine mileage is the old-fashioned way. Fill the tank to full, drive a known amount of miles, fill the tank to full again and then divide the number of miles driven by the gallons just filled.

Don't forget, c410006, there are no points for second place.

~17 :rock:

i guess around 25 if i try really hard to be boring

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.

All I know is I can get the computer to consistently say 28 - 30 mpg on the highway with 93 octane

onzedge, your alot brighter than you look

Thanks!

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??
