Hi..

I have 2008 - 1.6L versa.

I do not get good mileage compared to what is should be getting as of 1.6L nissan engine.

I usually try to drive around 100 kmph if im on highway.

I do some quick acceleration till i reach around 50 kmph... (not crossing 3000 rpm).... then continuing with gentle acceleration and then cruise at the desired speed...

i get around 8.2L/100 km at the best and an average of 9-10 L/100 km.....
which is much lower for a small car... (i know 2.4L cars getting this economy)
i expect 6 or 7 L/100 km....


what could i do to improve efficiency?
what is the most economical speeed for versa? [i get 2000 rpm for 80 kmph]
should i accelerate gently in lower speeds, or do a quick accelerate to reach the cruising speed quickly?

tips tips? =)

 

[freddddddy]

THANKS GOOGLE, 8.2L/100km = 28.7mpg for everyone on here.

Well if you're going 100kmh that's actually good, any faster and you're losing gas efficiency.
Gently accelerating will definitely help during the lower speeds. At least that's what I do and I get around 34-38mpg = 14-16km/L. I notice when I accelerate quickly (3K rpm +) it eats my gas way faster. Hope it helps

 

[sgvaibhav]

thanks...

will do gentle acceleration after my next fill-up... and see how my mileage goes by...

then i'll update here

btw, which can be considered as the most economical speed? 80/90/100kmph?

 

[sgvaibhav]

hi.

ok here it is.
finished my full tank

i checked my ENTIRE stats log, and i'll state it here


AVERAGE FUEL CONSUMPTION = 24.42 mpg / 10.38 kmpl
LAST FILL UP FUEL CONSUMPTION = 26.27 mpg / 11.17 kmpl

During the entire last fill up, i did the best economy driving i could ever do. Never revved - never crossed 3K rpm..
Drove without a/c lots of times.

Around 65% driving was highway.
Accelerated as gently i could to save fuel.
Average speed was around 80 kmph - 90 kmph (50-55 mph).

Now is this normal, or is something wrong?
I did the best i could do my driving style.

Check your tire pressures and switch to synthetic oil!

 

[sgvaibhav]

Keeping Front 33 psi
Rear 32 psi.

But i always add 1 extra psi while fill-up to compensate for any loses.

 

[08versailles]

sounds like your mpgs should be better cuz you're doing everything right.
how many litres and km at fillup? which transmission?
i filled last night about 42L for about 595km= 40 miles per imperial gallon
low fuel light came on at about 580km
down a bit from lots of running around/short trips
i use synthetic oil too, tires 38 psi, lots of rural driving at 90km/h, not much city

 

[sgvaibhav]

ok
i have automatic transmission, i fill full tank. [i guess my fuel tank is 45L capacity 'maybe']
last fill up was 41.63L - got 465km = 31.55 miles per imperial galloon.

i know i drive a little more around city, but i still think my economy is horrible...

reading about ur fuel light coming on at 580 km, i have done 560 km MAX on full tank - with low light coming on at around 530 km. [so i tried my max range i ever could.

isnt 38 psi too high?
how much extra has to be put in for synthetic oil?

 

[08versailles]

i find 40+ psi too high, 38 just right
oil volume same for synthetic or conventional
hmmm yes 1.6L motor should give better mpgs, but not as good as new 2012+ sedans with cvts. i dont know if you can get 4 speed automatics any more
i believe fuel tank is 50L, i've put in 48L once

 

[sgvaibhav]

i just remembered all of a sudden...

How important is it change fuel filter?
I got 107K km on my odo, and i havent changed fuel filter.

Does fuel filter impact mileage?

Yes big time. I had a pick up that had dropped down from 15.5 to 13 mpg and had no power on hills. I change out out the fuel filter at 140k and it was like a new truck again.

A tune up in general may help. plugs, plug wires, air filter.

 

[bstewart8]

I get like 24 mpg city...

 

[sgvaibhav]

Ok Next step - synthetic oil + fuel filter

any suggestions on which synthetic oil?

I'm new to this forum - signed up specifically for this post - and I'm getting terrible City mileage. Not even remotely close. If my conversion is correct, the City mileage for the 2012 Hatchback 1.8L should be 28mpg - or approximately 8.5L/100km. I'm getting a stunning 14L/100km (as per most recent fill-up). I've been really gentle on acceleration, simply because I wanted to make sure it wasn't my driving behaviour. I consider the car broken in, because I have put almost 25,000km on it since January of this year. The only thing impacting my mileage beyond driving would be the fact that ok in northern Ontario, so sometimes I have the car idling for twenty minutes before taking out. Even so, I can't see that eating into my mileage that bad. It's getting really frustrating and I'm thinking of going to my dealer with my most recent numbers.

 

[08versailles]

Welcome!
I know it's not as cold down here [coldest was -26] but i never let it idle to warm up.
Start it, scrape it, go. Try for a few fillups. Fuel/air mixture is extremely rich during cold idle, and won't warm up readily until the engine starts really working ie moving the car.
Make sure you're not low on oil first. Which transmission do you have?
I'm south of Hamilton, where ya from? Welcome!

 

[sgvaibhav]

i idle the car in D during start-up xD

 

[Greatwhitenorth]

I'm from Timmins, so probably a few degrees colder than Hamilton area

I've got the Continuously Variable Transmission, which is also the source of another problem for me (which also may be affecting the mileage).

 

[Versa12]

Winter Blend of fuel is out now and has less energy in it which results in worse MPG then the summer blend of fuels.

Quick acceleration pours fuel into the motor and makes it work alot harder which destroys mpg.

Are you letting the car idle to warm up in the morning for awhile? If so you are getting 0 mpg.

 

[sooner4x4]

+1 on Versa12's comment; 0 mph = 0 mpg.

Synthetic oil will not yield a mpg gain that can be measured. Lots of misconceptions and misinformation floating around about that. Yes, there may be a fraction of a mile per gallon increase but it would be masked by more common and significant variables. (driving style, tire inflation, winter gas blend, altitude, head winds, dirty air filter, etc.)

The CVT tranny will yield 10 -20% better mileage than a comparable 4 speed automatic. This is true on the Versa and on the Subaru's. Read through a few hundred hours of forum posts and this will become apparant. Yes, I own a Subaru also (with the CVT).

If your Versa has over 100k miles, it is due for new spark plugs. This can definitely yield better gas mileage if the plugs are about worn out.

Bottom line, there is no magic formula to increase gas mileage. The biggest influence is driving style. The Versa gets less than average fuel economy for it's class and size of vehicle, especially in the four speed auto version. My much larger, heavier, taller, AWD Subaru Outback with a luggage rack gets better gas mileage than my Versa.

 

[Greatwhitenorth]

Does idling my car for ten minutes before I drive it really burn that much fuel, though? With the CVT, good driving behaviour, and a broken-in engine, I feel that my 2012 Versa should be getting better mileage than HALF of what the company advertises.
