What's the best ways to improve gas mileage on the 4th gen?
I've been driving a lot more recently and with gas prices above $4 I'm interested to know what things work best to improve mileage on the 4th gen Maxima?
So far I've read: Use premium fuel, don't use fram air filter, don't accelerate rapidly from 0, the hotter the girl in the passenger seat the better mileage you get
What else?

That's more a general than a specific question. Make sure your tire pressure is correct, tune up (replace your spark plugs, ignition coils rarely go out but sometimes do, air/fuel ratio sensors, replace your filters,and oil change) and you should see a difference

1) Avoid Rabbit Jumps
2) Lose Weight
3) Throw out unnecessary weight
4) Tune-up : Spark Plugs, Air Filter, Fuel Filter, PCV Valve. Clean out TB, IACV, EGR tube. Make sure you used 5w-30 for oil.
5) Proper tire pressure.
6) Coast to a red light/stop sign. Check out more hypermiling tips/forums
7) Use cruise control on the highways [Drive at the posted speed limit]
8) Buy Coilovers (Aerodynamics)
9) Avoid anchors (Wheels)
10) Make sure Knock sensor and your o2 sensor's are working properly.
I accomplish 22-25mpg with 70city/30hwy (Heavy traffic here in Los Angeles, CA) with no mods. Make a fuelly account to keep track of your mpg's.

Most of it is driving style. I highly recommend the ScanGaugeII or ScangaugeE, being able to see how your driving effects your fuel economy really helps. http://www.scangauge.com/products/ I went from a city best of 26.9 mpg to 28.6 after driving with the scangauge installed for a couple tanks. You would pick up more mpg than I did if you aren't using any hypermiling techniques already.
I also picked up and extra 5-15 miles per tank after various performance mods.

+1 on Maintainence, I picked up ~2mpg from new spark plugs alone.

Agreed about driving style.
I just drove 466 miles on one tank...avg spd 72 MPH, with radio and air conditioning cranked...and I got 29.56 MPG.
If the car is properly maintained in the first place, the mileage will show as a result.

doubt the radio has anything to do with gas mileage lol

What tune up's does Nissan recommend at 130K miles, anyone have a link, I didn't see a link in the stickies.
***where did you guys buy your NGK spark plugs and how much did you pay for each one?
*** whats the best price you've seen on O2 sensors?

MPG is calculated based on realtime engine management/monitoring parameters of sensors. These info can be acquired via a good OBDII scanner. Realtime rpm, tps, vehicle instantaneous speed, ... are included in the calculation. You can also monitor timing advance, fuel trim, IAT, and adjust your pedal to go light/easy or hard. I'd rather invest in an OBDII scanner for tuning your car.

The amount is negligible to most.
You can't tune an A32 with an OBDII scanner.

I've had my dads car just over a year now. I drive roughly 60 miles to work (and back) with about 45 of that freeway, mostly 70 mph. My worst fillup MPG was 26.7, my best just last fill was 31.2. I frequently see 29.6 - 30.x.
I've noticed the biggest impact on my mileage is going over 2500 RPM. Whether it's from acceleration or cruising, if I got over that I'm closer to the 27MPG.
My car is all stock, some Firestone 50k all-season tires at 32PSI. I put between 89 and 91 octane and that seems to have hardly any impact on my mileage unless I run 89 four or more fillups in a row.
I've never gotten less than that 26.7 and that was mostly running around between the malls and home with the wife on a 300 mile weekend shopping spree.

He's probably using Ethanol-free gas. http://pure-gas.org/index.jsp?stateprov=LA

Just replaced knock sensor and I got 32 hwy, but even with the bad KS, the DH regularly got 35 with it. We get ethanol free gas when we can, but usually just have to go with whatever grade premium we can get. We swear by Michelin tires though. Just put new Defenders all around after running over 100K on the old Michelins. Great blend of durability, MPG, traction, ride quality and noise level. They always give us our money's worth.
