Bad Mileage

i would say #2, even when up to 140k, cuz you're in your most economical gear, covering the most miles per unit

Hello,
I'm new to this forum as I just bought my Nissan Versa last week. I am also concerned about my fuel economy so far. I drive mostly in the city but this past weekend did a highway trip up to the cabin and was not impressed by the fuel economy. I have a 2007 1.8S with the 6 speed manual. First I was amazed at the 3,000rpm at 100 km/h. On 3/4 of a tank of gas i only got 270km.....i have a V6 jeep that gets better fuel economy then that, and has a simliar size tank. According to my manual i have a 50L tank, but I just filled up after the fuel light came on and it only took 38 liters....Either way I bought this car thinking I'd be able to get at least 450-500km to a tank. I changed the transmission oil, engine oil, coolant/antifreeze and air filter this past weekend as well. I drive the car, in what my mind, to be very friendly. Never go over 3,000 RPM, and I'm always in 6th gear when i've reached my cruizing speed. Anyone have any suggestions or comments? Thanks

Versamack04 how many miles on your 2007 Versa? I have a 2009 and my average over 44000 miles is 33.4 MPG (US miles) or about 7L/100Km. My best tank was 600 km. The O2 sensor impacts fuel mileage and is typically recommended to be changed at 100K miles.

I currently have 104,000kms or roughly 64,000 miles. No engine light or codes. Brand new air filter, and spark plugs are good and according to the manual don't need to be changed till 160,000kms or 100,000 miles. Car seems to be running fine, idles and revs fine.

First of all, welcome to the Versa world!!

I usually do a mix of highway / city driving, and just filled up today. The fuel light came on at 492km, giving me roughly 8.0L/100km. A few weeks ago I was driving to Toronto & back daily, and was getting around 6.8-7.2L/100kms, and that was surprising considering that it was mostly stop & go on the way home. I usually try to keep the RPMS as low as possible (a little easier to do so in the CVT) and keep to the speed limit ... but I will still pass on the highway if need be.

I dont drive economically usually shift at 2800rpm but it frequently sees 4500rpm under light load(like getting on an on ramp) . All my driving is in town and im still managing 27mpg. Question deos the base 6spd have a low fuel light and when deos it come on? Ive had less than an eighth tank and it didnt come on.

Yes, the 6 speed does have a low fuel light. It came on at around 1/8th of a tank left, and i drove another 40kms or so on it before i fueled up, which put the fuel gauge right on E. In my mind the car should be able to go more then 270 kms on 3/4 of a tank though, and it was all highway driving.....when i filled up from E to Full it was only 39 liters....after doing some reading i'm assuming the car is either a 45 liter tank, or i can drive it for a long time past Empty...according to my owners manual though i have a 50 Liter tank....so i'm not quite sure...obviously if it is a 45 liter tank it will get less kilometers...but I'd still like to figure out why its not getting the fuel economy it should be....

Welcome versamack04!
I too was alarmed how high the revs are in sixth:driving:
I've found city driving is a killer, and so is anything above 110km/h.
Lots of factors can help a bit but the biggest one is easy on the go pedal.
Enjoy the nvf!
edit How cold is it out there? I had to scrape heavy frost Monday morning

Thanks for the welcomes! Well 08versailles, its acctually been pretty hot around here lately. Raining lots but definatly around the 18 degree mark, right now its only 9:55 and its already 20 degrees in the sun....I guess i'll just go easy on the pedal and see how it goes. I upped the tire pressure to 38PSI, and I did purchase some fuel system cleaner which i'll add at the next fuel up and see how it goes.

Question : HR16DE engine

Route 1) Bumper to bumper traffic.
Extreme stop and go. Harsh acceleration at any moment where gap is seen.
Distance : 22 km
Time taken : 40-45 mins

Route 2) Empty Road.
Fast driving. No stop and go, but fluctuations of 120km/h to 140km/h (74 mph to 87 mph).
Distance: 65 km
Time taken : 50-55 mins

Route 2 is mentally more relaxing since its open roads, no battling, nicely driving.

My Question - which route is more economical in terms of fuel consumption?

just curious did you change your radiator

no
going at 140 should'nt cause heatup's i guess.

Route 1 is going to sharjah using ittihad road
Route 2 is going to sharjah using bypass road - best empty road to travel during evening hours of traffic. no cars = no fighting for way


But my radiator coolant is filled to max always.

hmm because my friend has changed his radiator for 2008 tiida and for some strange reason it uses more fuel

was the battery disconnected while the radiator was being changed out? After disconnecting my battery my milage went from shit to super shit. When the ecu loses its fuel trim memory it all goes to hell and takes what seems like an eternity to come back..........seriously starting to hate this car

Might be a bad O2 sensor, making your engine run rich.

yes it was

Hey just giving a fuel mileage update on my car. I upped my tire pressure to 38psi and drove it as nicely as possible...i got 500 km's, which was all city driving, and just filled up today after doing a full tank highway driving and got 620 km's till it hit E....so definatly an improvement from when I first got it, and definatly pleased with it.

Hmm i tried all speeds and its the same consumption

Yup that is what you should be getting. I just ran 530km mostly city and filled up with 45L, which works out to about 33mpg. I'm not running 38psi only 34. On the highway without AC, easy to get 600km +.

I get 30mpg mostly highway between 65-70mph. Kinda wish I got the auto for the extra 4mpg due to taller gears but then it would be a slow turd so its a catch 22 I guess.

Along these lines, is there a way to make engine run a bit lean?
Something crazy like insert a small resistor into the O2 sensor line, either series or parallel?
I always wondered if that was a viable experiment.
I assume very lean on fuel is bad for the engine.
