i dont really pay attention to gas mileage or anything and was wondering how far can i go on a full tank, an average. im doing a cross country trip and need to figure out about how many gas stops and such,, thanks in advance. (for your info i plan on driving 80+mph as much as i can,, NJ to lake tahoe is FARRR)

 

I get usually ~400 miles.

 

Whwn I average 78 MPH, I get 460 MPG. Anything over 80, your MPG goes down the tubes.

 

Plan on stopping about every 375-400 miles. When I run up to VA from SC I set the CC @ 79mph and I average about 24mpg. Just FYI On Christmas I borrowed a Passport 8500 from best buy and made it from Fairfax VA to Columbia SC in 5 hours and 45 minutes. I probably averaged (with stops and all) around 85mph. Most of the actual time driving was spent between 95-100mph. You figure 490 miles in 5.75 hours. At that speed I only got around 18mpg. It really helped that there was no traffic too.

Just so you know how fast that really is, it normally takes 7 hours doing 7-9 over the speed limit the whole way.

 

I get 350-375 MPG, but maybe that's so low due to my driving style.

How the hell do you squeeze 460 miles out of a tank at 78mph? Are you going down hill with a tailwind the whole way?? Or do you run it dry?

 

I average 27-30 MPG on my mixed driving. It's true that your mileage goes to crap when you exceed 80. Make sure your tires are properly inflated. I usually go with 36 PSI in the front and 34 in the rear on my 235/45/17, but it's the same pressure I used with my stock tires too. Drive with the windows up, sunroof tilted (avoids clastrophobia), and pop in a good CD. Just make sure your car is properly running since this will be a long trip.

 

I was able to get around 380 miles on a recent trip. All highway and averaging 75mph and 3 people on board.

Not very good IMHO, then again this isn't an econobox.

 

I get 22 mpg on average... something a little around 370 on a tank

 

I run it down to the grissle and I drive with the cruise control set. On long trips, don't like to accelerate hard so that helps too.

Ask some of the NE fellas(well medic knows)that went to Maxus. I drove from Boston MA down to DC on 1 full tank.

 

On the highway...about 27-28 MPG cruisi' a little over the speed limit

My all time low...about 13 MPG during the winter driving back and forth to the train station 2.5 miles away.

 

460 MPG??? Daaaaaaayyyyyaaaaaaammmm!!!!

By the way, joking aside , now that its cold out, to get the best mileage, leave your climate control in economy mode, not auto. With auto mode, the AC compressor stays on.

My mileage typically hovers around 20mpg during everyday driving.
The best mileage I've seen was 27.5mpg averaging 80mph, on a drive down the coast from Monterey.

 

i need to go more country driving and see what i get, i usually get 300 in the city, but i sit in traffic and drive around full parking lots all the time so i waste a lot, and i dont take it all the way, i dont wanna learn the hard way

 

I put about 350-360 miles on a tank. I usually put about 16.5 gallons in. That works out to 21.8 mpg. Its 90% city driving and I'm a leadfoot.

 

low mileage could also be due to the ac compressor being on correct?

for example lately i've only been getting
a little ~280 miles per tank.

but i remember the other tank up before that, i almost reached 380... maybe i hadn't had the AC on all the time, to defog the interior?

weird...

well i'll be driving to toronto from montreal tonight. leaving in about 2 hours. I would like to do like last time and do the trip in around 4 and a half hours ;-) instead of 6... but for fuel economical reasons, i'll probably stick to around 120km's or about 72 miles and hour.

The most efficient speed to cruise at is what? like 60 miles an hour, or 100km's here in canada? Or has that gone up a bit? or?

 

multiplexor, eh? Are you a CSE student?

 

hmm, i want better mpg, theres got to be a good solution, btw does anyone know if the prcai adds or takes away mpg, i heard its better because there is more usable air but i could be wrong

 

My 95 averages about 23MPG, my 02 get's about 20 MPG. My average spped is usually 31 MPH{atleast that's what the dash say's}.

My old 98 I30 averaged about 21.5 MPG.

 

22 mpg
17 mpg with nitrous....

i'm getting around 280 miles a tank with 60% city / 40 % highway. All highway, I can get 320 or so. All city I get 240-270.... I still need to get new spark plugs and i'm going to try and find time to change my PCV valve and clean the throttle body this weekend.

 

Yep, and I stopped for gas twice.
