I am getting consistently 20-21 mpg on my 350zr. I drive about 50/50 cty/hwy.

I baby my Z. I shift most of the time from 3-4k rpm. I have 33k miles on my car. Stock everything. I am running 19's. Is this normal for most of you?

 

Sounds about right. You could be shifting a little lower though. The car has enough torque around 2.5k-3k to keep it smooth and reap greater MPG as well.

 

No.

 

^You didn't need to quote his msg to respond like a dbag, noob.

 

Did you start another MPG thread? Kill yourself.

 

I would say that is about normal. I'm currently getting about 24 50/50 city and highway. I'm on stock 18's with mods below in sig.

 

I get 21-22 consistently, drive easy 90%
of
the time. All our gas has 10% ethanol which lowers it a bit.

 

So .

 

and I wasn't being a "dbag"...all I said was no thats not normal for me.

 

I get between 19-20 with mostly city driving and only acting like an *** occasionally. All stock besides popcharger.

edit: Im also driving a coupe, you weigh more AND get better MPG... lucky

 

What year ZR?

My wife's 04' ZR averages 21-25mpg highway/city.
My wife's 07' ZR averages 16-18mpg highway/city.

The difference was noticeable on the first tank, and has been consistently 3-9mpg worse than her 04'. Both with the same wheels, tires, and mods.

 

I average 18.5mpg in my 06 ZR.

 

It's normal. If the wheel/tire combo are heavier/wider than stock then you would be losing mpg. You can also shift sooner as previously mentioned.

 

I have an 04. By the looks of it, I think im doing alright with 21mpg. I am going to try shifting around 2500-3000 rpm to see if it makes a difference.

Would adding the Motodyne 5/16 plenum lose MPG as well? With same driving style.

 

The plenum upgrade is a good mod to do. You should'nt lose any mpg. Just keep babying it like you've been doing at low rpm's and you should be fine.

 

15 mpg

 

yes its normal, you could get less u could get more, iv gotten 24-25mpg shifting at 2k putting it in 6th at 37.5 mph its not really much fun though lol

 

thanks guys. I plan on getting the 5/16 motodyne plenum. Did you guys feel the power difference after the mod?

 

I wish I got 21 mpg, It seems the HR's rape gas.

 

I got the 5/16 spacer with the MREV 2 and feel a substantial difference in the mid range. Sounds pretty good too paired up with my intake and exhaust.
