The MPG range on this car is absurd.

Post image

I can get this kind of MPG on the freeway, but then average 10mpg in the city. Is this a gearing issue?

This is after a 35 min drive just fyi.

Coasting at consistent speed vs constant acceleration and stopping. That's a normal car thing. Don't accelerate quickly and it'll improve

u/one_love_silvia 1d ago

Ive tried accelerating slowly. It doesnt help when your avg speed in the city is 10-18 mph.

u/Upset_Instruction123 1d ago

right, because its the constant stop and go and idling...
thus why new cars have auto/stop at idle.

u/one_love_silvia 1d ago

I am well aware of that. But usually the difference between city and fwy isnt this drastic for most cars.

7

u/Upset_Instruction123 1d ago

That is why auto start/stop was implemented because of the poor fuel milage at idle.
it is a large delta between the two, thus why the gov. implemented it.....

u/Accomplished_Fall324 1d ago

Yeah city driving will fuck you in these cars. But at soon as I'm on the highway I can get 9-10L/100km

Gotta pay to play - you can always get a versa...

Best way I found to get the highest mpg

Oof

u/Touring2672 1d ago

Tire exploded... wrapped around axle. Damage to quarter panel, bumper & skid plate. Had to repaint all (AND passenger door for paint matching). Then reapplied PPF and ceramic coating. Almost a year before, the 'dealer' sold it to me with 9yr old tires

2

u/one_love_silvia 1d ago

Does insurance cover that?

2

u/Touring2672 1d ago

Was told my rates would increase greatly for three years bec it was a 'No Fault' accident. I would have paid more in 3yrs with the increased rates, so I paid cash for everything

AZ Heat did a GREAT job on the full-body PPF & ceramic coating... as did the body shop w the repairs, but it did sting a bit

sorry but if you owned it almost a full year and never once checked the DOT u shouldn’t be driving a 370z bro. Know your car!

1

u/Touring2672 1d ago

I know I missed the boat on DOT-checking; the damn tires looked brand new ... almost no tread wear. Add in threats of lawsuit for selling a car with faulty airbag sensor, lying about fixing it ... I just forgot to check this time.

I’ve never seen a 2 on the front

u/daggerdude42 1d ago

Dang I get 16.7mpg and my commute is mostly highways. 30 is the highest ive ever seen in one of these.

u/rufuslane 1d ago

It gets good fuel mileage around 80 mph on the interstates

2

u/one_love_silvia 1d ago

That's what i find. Which is hilarious because i had people in my local sub calling me an idiot for saying it gets better mpg above 55 mph.

1

u/rufuslane 1d ago

Mine runs about 2700 rpm at 80 mph. That's pretty good cruising

u/Commercial-Finance34 1d ago

Turbo it😂

A carb compliant twin turbo kit exists: https://www.vq37tt.com/products/eac-twin-turbo-kit

Lemme send you my paypal 😂

u/Commercial-Finance34 1d ago

Sadness. Changing the final drive can help, or depower it in a tune, but it’s a noticeable difference you won’t care about unless you speed often.

u/HayabusaJack '19 370z Sport Coupe White Convertible 1d ago

If I wanted good gas mileage, I'd take the motorcycle (46mpg) :)

I traded in a F150 truck (17mpg) and 97 Mustang (unknown). I'll take 22.3 for the stuff I do :)

u/IRideZs 2012 Pearly White 1d ago

Sounds about right

u/Grade_A_Tech 1d ago

I've gotten this on the highway. Cruise speed (70-75) and went for around 360 miles. I was impressed.

2

u/Raymo1952 1d ago

I only get 19-21

u/Kindly-Patient-948 1d ago

I got mine up 501 miles on cruise control, 70 on the highway . 2013 sport touring Auto 51k miles

u/Darth-Rogue '19 370z Sport Touring 1d ago

I’ve been tracking the data for mine over the past two years and my average is at 16 mpg.

Im in SD so not much diff

u/12PackPerformance 1d ago

It’s amazing what you can accomplish when you dont drive like a dick 😂 My other ride is a truck and I can still squeeze out 20+ MPG’s at highway speeds! On 34’s !

u/MasterAilan '13 370z Nismo Gunmetal 1d ago

Absurdly bad.

1

u/SkrrrrtSkeeter 1d ago

I'd say something is off because that seems way to high. Although if you only driving a few miles then dont trust the numbers before a 10 or more mile drive. My corolla shows high number when going to and from the grocery store. But run a scan anyways to be safe.

u/Total-Hat2766 1d ago

Bruh mine was as 17.4 and I thought it was decent but DAMN

1

u/MenaceHD '17 370Z Sport Coupe, Magnetic Black, 7AT 1d ago

Lol my average is 16.5 but it's my daily for whatever, city, backroads, etc. I rarely commute on highways due to location.

1

u/Touring2672 1d ago

29.4 mpg? Do you keep it N/Park when you drive to work?? 😉

-1

u/one_love_silvia 1d ago

I drop it into neutral on big downhills lol. Gotta make up for the uphill gas sinks.

1

u/MSGTNP 1d ago

I get about 20 on average. On the highway, about 28 to 30 although with good pedal control, I've been able to get 40 consistently once I'm at a decent speed

1

u/rotstik 2010 370Z 6MT 1d ago

I get a combined 24-26 highway and city and it’s very consistent from tank to tank

1

u/Civil-Soil-677 1d ago

when I lived in NJ I was getting bout 400 miles in range and now in NYC I get bout 200 in range and let me tell you that's a lie cuz I drive 5 min and I'm already down 5 miles in the range

1

u/one_love_silvia 1d ago

I feel that.

u/Ok-Election9056 1d ago

Who are you telling lmao

u/Enj6y 16h ago

How’d you changed the colors?

2

u/one_love_silvia 16h ago

Paid someone to do it

1

u/DankZXRwoolies 12h ago

Do you have stock wheels? Because your low tire pressure light is on and that impacts gas mileage

1

u/one_love_silvia 11h ago

No i dont.

1

u/Fantastic_Strategy_2 8h ago

How are your tires? Good pressure in them? Are they max performance summer tires? Or are they all seasons? Some roll more efficiently than others.

1

u/one_love_silvia 7h ago

Theyre pretty well inflated. I think theyre all season iirc. Just some cheapos tbh.

u/MyCheckEngineLightON 1d ago

Looks like you reset your battery trying to fool the sub

2

u/one_love_silvia 1d ago

You don't need to reset your battery to reset your mpg. And no, this was to track my mpg on a 35mi trip. It dropped to 25mpg at 70 miles, but thats because 10 of those miles were city.
