Nissan Sentra Real World MPG

I am getting abt 30.5 mpg (average), as per the trip comouter, mostly highway driving. 80% highway and 20% city driving. I have seen highway numbers go as high as 36 mpg but since city driving numbers are not good, the average does not go above 30.5 mpg.

#4 of 88 Sentra SPEC V: Horrible Fuel Economy???? by kermitmbi

Feb 28, 2007 (10:29 pm)

I have a 2002 spec-v. 90% of my driving is city and the speed limit where I do most of my driving is 30mph so its not like I can drive it hard. Every time I fill the tank I calculate my fuel economy. I'm consistantly getting 17mpg (when the whole tank is used in the city). The best I've seen on the highway is 26mpg. I don't drive the car hard, my air filter is clean, my spark plugs are new and my tires have the proper amount of air in them. I don't want to take it to a dealership until I know I've tried everything I can. Is this normal or a problem??

Hi James,
My car is a Nissan sentra XE 2001. I am getting very low gas mileage. I went to mechanic, they found problem with O2 sensor, then they called Nissan, and found that it was due to problem on camsensor which was on a recall. Then nissan fixed it for free, then my mechanic checked the O2 sensor and seemed OK, but still I am getting low gas mileage, practically same as before. The mechanic told me there was no problem in the car. I am getting 17 MPG during winter.
But other are getting around 25 MPG during this time of the year. Any expert comment would be appreciated

#8 of 88 Suggestion by james31278

If you haven't already I would suggest trying a K&N performance air filter. When my Grand Am had the stock filter in it, it was like the car was scruggling to accelerate and after I installed the K&N the car was much more responsive than before. I may also suggest putting on a inexpensive semi larger catback type exhaust pipe because those tailpipes on the "economy" Sentras look too small and maybe hurt gas mileage, the easier the engine breathes the less stress on it in my opinion. Those stock air filters are crap with a capital C, it is like trying to breathe through a straw.

none of you guys are really having a problem, if you have the 2.5 litre engine that is. The new epa sticker for a 2002 spec v is 19/26 which sounds exactly like the range you are getting. Its a performance engine, not a hybrid.

No mnan, mine is 1.8L engine!!!
I have another question, hot air comes out of the vents even when the fan is not truned on. if I put the temp knob to cold region (blue), then cool air comes out. what is it? is it that the heater or AC is truned on even when I dont turn them on!!! all strange things happening. I had a subaru car, such thing never happened.
