gas mileage
 

So I purchased a 2013 370 NISMO on 15 Jan 2013, It recently got totaled on 17 April this year. My gas mileage avg 18.7 mpg, and my gauage would show appx 325 - 350 miles to a fill up. I just purchased another 370z NISMO 2014, im averaging low 17.6 mph, and a fill up shows 310 miles to the tank. A friend mentioned to disconnect my battery overnight, to let everything re-set and compute for altitude changes from Clovis NM 4,295ft to Albuquerque 5,355Ft. Does this make sense ? and are there any dangers to disconnecting battery ? other than having to reset clock, garage opener etc.. Thanks for suggestions and help

to my knowledge there is not danger in disconnecting a batter, just make sure you tighten everything back up... did you just try resetting your mpg counter to 0 and a couple times and see what you get that way. maybe your foot got heavier so you're getting less?

LOL... I know as the temps rise, the less fuel you can put in the tank and the car is starved of oxygen which can lessen the gas mileage as well. will keep an eye on it.

Put gas in the early morning when cold during fill ups.. use the low speed setting on the trigger.

I might have to restart mine by disconnecting. I think im at 13 mpg.

cool let me know what happen. Gonna do mine tonight..

No need to do this. After a few key cycles of turning on and off your car your ECM will adjust.

i honestly don't even want to look at the mpg cause it's not that good on gas, i always have the outside temp displaying lol

LOL.. I check my mpg almost daily to see if any improvemt.. definately gonna try those suggested tips tho.

i did for the first week of owning the car, after that i gave up lol. i know a tank lasts me about 4 days max.

New car is going to be tighter. Give it a few months

thats all i get now too. My other Z i could ride for a week.

If you disconnect your battery (I don't think it's necessary), just be sure to do the window reset procedure. And if you are going to be opening/closing the door while the battery is disconnected, be sure to lower the windows at least a little before disconnecting.

Mine has 500 miles on the odometer and my gas mileage is climbing. I'm at 21mpg now but drive 25miles to work mostly highway. Sure hope it gets better than that!

I am not sure how people can get 20+ mpg on this car. Stock I was averaging 14mpg. Now with a giant turbo sitting there, I am getting somewhere between 8-12mpg.

I guess some of you guys bought a sports car to granny it.

Even if I drive it spiritedly at various points, I still manage 20mpg. I don't hotrod it every where I go, because for one it's not possible on my commute to work, no matter how hard I try, and two I still have to watch out for 5-0 so I try to keep it reasonable so as to have a chance to save my *** from getting a ticket.

AMEN my man, im getting 14 mpg stock so when i see these 20 mpg numbers im pretty shocked.

I don't try to drive for good MPG, but I have tracked it using Fuelly since the very first fill-up. Now, 50 fill-ups and 11,500 miles later, my average is 22.9 MPG. I don't baby it, I just have a lot of highway between my house and the office.

Luv that 5-0 comment. Mahalo from HI :tup:

I'm at just over 2,000 miles, primarily interstate & highway. ~23 mpg.

I'm in Albuquerque too with a 13 nismo, but my numbers are significantly different. 379 range on fill up, 20.1 mpg with 19.4 mph. And by no means do I ever granny it lol. I want to know if its my UPREV econ mode at work so please post your results after you reset it.

If 21 is all you guys are getting on the highway, how in the heck did the government rate these cars at 26 highway? Being pushed? I thought the EPA was more accurate.

how can i improve mpg

try driving in reverse :P

If it's all highway, then I can push that 26, even 28 - well, before my exhaust. I'd assume it's about 23/24 now with the exhaust/HFCs. Haven't done one in a while, but I did see an avg drop in mpg after the install, and it's been consistent for a year.

great feedback.. I dont think I will do the battery disconnnect, will just wait. I did howerever try the start then off, then start a few times. Will see what happens. Im due for a fill up today. Seems like Im always at the pump with this Z vs my 2013 Z.

i have a 2013 and i'm still always at the pump lol, but granted i drive about 100+ miles a day

WOW, those are some great numbers. I get on mine here and there to and from work, 40miles round trip, im at 17.6 mpg, and fuel range at 320 miles tops.. ugh...

i used to drive an rsx-s to work and back.. i usually got about 30mpg, i miss those days :( lol

I would say too that changing all fluids to synthetic would help a smidge. I just hit 21.8! Yahoo!!!!

No way... Lol :-)

When I had my 09 manual/sport/base w/ nismo exhaust and injen intakes, I averaged 22-23 driving pretty aggressively. One trip to NC from Florida, I averaged 27-28 highway at 80mph and got almost 500 miles to a tank. With my '13 auto, I got about 20 combined. With my new '14 sport/manual, I'm getting 21-22 combined but its still got less than 1k miles on it. The best average I ever got was when I was modded.

Plus 1 more reason for mods!

When my gas tank get empty, I fill it up. Other than that, I don't worry about my mileage status. If I was that worried about gas mileage, I'd be driving something different.

Wow, that is worse than I get my GT-R.

In all reality it takes more skill to drive efficiently. I find it a challenge. :stirthepot:

Totally agree with you. Just by going to a true dual exhaust has increased 2 to 3 more miles per gallon on my Z. I'm averaging 23 on my commute back and forth to work and 27+ on road trips plus picked up a few ponies along the way. Best mod for me thus far!

Yeah, the highway is where I saw the serious MPG gains consistently.

I once put 500 miles on a single tank of gas in my 370z. One thing I have noticed is the Z gets near its EPA suggested MPG going around 80 MPH for highway ammount. If I really only go the speed limit 65-70 that goes from around 26-27 MG to 30-31 MPG.

Too bad the same is not for my GT-R. If I go 80 or a bit more I get like 20-21 MPG if I am lucky and I have to go 70 or below to actually get the EPA 24 MPG.

Not that I really care about the MPG that much but I am curious how the numbers differe so much in real practice for the cars considering the highway difference is only 2 mpg (24 vs 26)

Also, if I'm leading traffic, my average is about 21-22 highway at 80. If I'm behind someone, it'll go up to 24-25 at 80. Thats pretty sizable, but lower mpg>rock chips any day lol

First 1,000 miles in brand new 13 sport 6mt Z, 14.5 mpg, mostly city driving. Put on a different exhaust at that point and since then I've been averaging 16.5 mpg, same type of driving. Not sure if the engine broke in a little to help this but I think it's mainly the exhaust.

Skill? You mean will power to hold back. Lol
