When Nissan pulled the mpg out of their ass

se7enty7 · Apr 10th, 2003, 07:12 PM

They MUST not have been driving my car. I just drove almost all highway miles, and got about 33mpg.

Now.. maybe in PERFECT conditions, perfect temperature, and DOWNHILL the whole way, you MIGHT get the advertised 39mpg. My car is tuned up perfectly, good o2 sensor, and cruise on the whole time. This is ghey.

They probably got it driving DOWNHILL, with the wind, on a crisp 70 degree day with a 98lb weakling in the car using octane booster and nothing else in the car.

I mean really.. I am going for mpg here... That's why I sold my v6 grand am and bought this ...

I thought car manufacturers had to like.. give accurate figures...

I have a 5 speed, FULL tune-up with ngk plugs, nissan wires and everything... and drove all highway and get 33mpg..

Granted it was through somewhat mountanious ga/tn area... but still.. im going up just as much as im going down..

10-1 says its your CAI and wheel/tire package if they were on during the trip.

PatScottAKA99XE · Apr 10th, 2003, 08:38 PM

Altitude it a factor as well.

se7enty7 · Apr 10th, 2003, 08:57 PM

My cai is supposed to increase mpg if driven the same according to myoung.. and my wheels and tires, while wider, are a lot lighter than stock..

PatScottAKA99XE · Apr 10th, 2003, 09:03 PM

Ok so we will rule out the CAI. Are you sure about your wheels/tires? Have you weighed a mounted and balanced one vs. stock. Seems I remember hearing somewehere that Nitto's are on the heavy side. Altitude would still be a factor. Mike is closer to sea level then you would be in your area. Just try trying to help you figure this out.

se7enty7 · Apr 10th, 2003, 09:33 PM

well, my wheels are 12.5 lbs, and according to discount tire the nitto's are 18 lbs, which is almost the same as the others, except falken who are 18.5, and ... blah, it was another popular tire that was 17 or 17.5 but had a horrible treadwear rating

Raise your tire pressures...even if they're already at the recommended pressure. It'll make a significant difference. On my last tank I got about 27mpg, and my car is as tuned as can be(not modded, just tuned to spec). This 27mpg was with 50% city/50% highway driving with loads of hills. While it might not seem like a lot, it's the best I've gotten without running the tank to practically empty. Reducing rolling resistance really helps. I have 195/95/VR15 tires raised to 43psi front, 39psi rear. While the tires might wear a little quicker in the long run(especially in the middle), lots of mountain road driving evens the tread back out

I can drive 100 miles before the gas level dips below the F (for full)

you cant drive a car on octane booster. I ran out of gas one time and tried it. doesnt work

Neil · Apr 11th, 2003, 11:37 AM

could it be how you were driving? doesnt lettting throttle wide open and driving at high speeds decrease MPG?

se7enty7 · Apr 11th, 2003, 12:15 PM

okay
1)
195/95/VR15 barnoun that is crazy profile

j/k... I have 205/50/15 and have the fronts at around 42ish, and rears at 39-40ish (that was when hot)

2)
The dude meant octane booster, and nothing else as in no speakers, no luggage, no nothing.

I really think nissan is just lying. I swear to god I do. I get 27 with 50/50 city/highway... but according to nissan you should get 29 all city...

sethwas · Apr 11th, 2003, 01:05 PM

Well,
On the highway in FL flat with no traffic doing about 65 I can probably get 40MPG (I can go to orlando and back and its barely 2 tanks). I just set the trip meter and fill up 10 gallons worth, when I get to empty, see how many miles, and divide by 10.
In the city I get under 20 if I'm lucky. 24 is mixed.

I'd say it has to do with your non stock tire and wheel combo which adds rolling resistance coupled with your speed and throtttle variance while driving in mountanous terrain.I had a 98 Sentra that actually got better than the rated mpg(it got 32 city).
