Gas Mileage for 2000 Nissan Maxima

Gas Mileage for 2000 Nissan Maxima
Hi all,
I have a 2000 Maxima GXE. I bought it about a month and a half ago. I am seeking some help/advice on the following matters and would greatly appreciate any inputs:
1. The gas mileage on this car has been around 20-21 miles per gallon including significant highway driving. Nissan claims this car gives 21 city/27 highway but I have not had mileage of over 21 miles per gallon despite significant highway driving. Can anyone tell me why that may be? Do I need to do something to the car to get better gas mileage?
2. I use premium gas (91 Octane) for this car which is what I was told is required for this vehicle. Someone told me that the low gas mileage may be due to using Premium gas as it is more refined form of gas and burns faster than regular. So by putting regular, I may improve my gas mileage. I am not sure if its true or not but I would like to know the Pros and Cons of using regular gas versus premium for my nissan and also if using regular gas would improve gas mileage or not.
I would greatly appreciate any responses.

Re: Gas Mileage for 2000 Nissan Maxima
How fast do you drive? How hard to you accelerate? Premium gas (high octane) gas means just that. Less likely to detonate, engine ping. If you use lesser octane gas, you'll get less than desired performance and your engine will or may ping or knock. The thing about high octane gas burning faster is wrong. High octane gas burns less easily and that's why you need it for our engines, high compression. You should get better gas mileage with high octane gas. Check your tire pressure and all the usual stuff associated with improving gas mileage.
Could get into more complicated diagnosis... O2 sensors, emissions... air filter, fuel filter, if clogged? , so on. Drive with your windows open... many factors.

Thanks for the info. I normally drive at 75-80 mph on the highways and around 35-50 mph inside city. I use 91 Octane for fuel. I guess I will get a tune up done on the car soon and hopefully that will help a bit in improving gas mileage.
Thanks for your response.

Just get a full tune-up if its near the time. My 99 gets great fuel mileage, i averaged 23mpg on my last monitored full-tank run, and that was with very very hard driving on my part. With a lighter foot i managed 25mpg, my foot cant get any lighter

The Maxima gets terrible mileage in the city, unless you keep the revs below 2500 rpm and go the speed limit all the time. But who buys a powerful V6 engine to keep it under 2500 rpm? No one. With my 4th gen, which I maintain religiously, I get ~16-18 mpg in the city, and thats trying to keep it easy on the go pedal.
On the highway, I notice a huge difference if I keep my speed around 65, as opposed to 75-80. I get around 26mpg going 65, and around 22mpg going 75. I hear commercials on the radio saying how going 65 vs 75 saves 10% on fuel. I do not doubt that. It seems strange that would be the case, but try it out, you will notice a mileage increase immediately. Its hard to keep such a good engine turning a tad over 2000rpm on the highway when everyone is passing you, but thats what you need to do to get good mileage.
Now, if you have a 5-spd, then its different. With 5-spd it probably has more to do with shift points rather than the speed you end up driving at.

Thanks for the info. but....
Thanks for all your responses; I really appreciate it. Well, even at 75-80mph on highways, the RPM is at 2500-2600 and rarely touches 3,000. In addition, I use cruise control on highways. As far as driving at 65mph, well the speed limit on our highways here is 70 mph and really I don't feel I can drive at 65mph in that case, lol. Still with 75-80 mph, the RPM is around 2500-2700 so the gas mileage should be around 25-27 on highways.
Anyway, I guess a good tune up and changing air filter may help as well as keeping the tire pressure correctly.
I appreciate all your help folks, thanks a bunch.
