23mpg@80+mph.

Doing 60-65 i imagine i could pull better numbers

 

i just drove 250 miles from orange county to fresno. i still havent pump gas yet my gas light just came on at 360 miles. its a 04' g35x sedan.

 

i got a 05 g35x and im shooting for 400 a tank. im driving real slow lol

 

i just pumped gas today. i pumped 17 gallons of gas. i had 370 miles on the odometer. so im guessing i could get over 400 miles on a full tank.

 

i was able to get 18mpg city miles, i dont know if thats good or bad.

 

just got back from an 1650 mile (round trip) venture from Phoenix, AZ to San Angelo, TX... I cruised at 70MPH from Phoenix to El Paso, TX (~425 miles) for my first fuel up, where I put ~15 gallons of gas into the car (from a topped off tank)... guess that averages to 28.3MPG... the rest of the way, and the way back, I averaged about the same...

I was really impressed!

EDIT: Forgot to mention this was with Premium/Super Unleaded (91 Octane), with average outside air temperature of ~105 degrees Fahrenheit between elevations of 1100 and 2600 feet

 

same thing happened to me a few years ago. i drove from vegas back to california. i filled up at the city limits of vegas and 400+ miles to the tank later, i filled up. i posted about it and got a bunch of haters saying that's a lie. the trip odometer is the only thing i used. i had no other test measurement equipment. just filled up, reset the trip odometer and away i went. right now in city driving in tampa i'm getting around 265-270 to the tank in the same method. this friday i'm about to start driving to california so i'm sure i'll be getting 400+ again on some legs of this trip. 6mt as well.

 

in the 03s the Cd was .26 for sedan and .27 for the coupe.

 

i call bs

 

^ good for you

 

very nice!!!!

i got 28.75 on a trip to the lake.. it was like a 3 hour round trip.. i did 60 - 70 almost the whole way.. and i rolled slowly up to red lights, trying to keep it in like 3rd gear.. i tried not to come to a stop

 

for the nay sayers. i'm currently driving from florida to california. i'm in a small town between san antonio and el paso. i took pictures of this trip. this leg of fuel began yesterday, i filled up in a small town in louisiana, 7 miles from the texas state line (pic 1) and drove to san antonio. stayed the night there and continued driving the next day. i took the next pic at ~150 miles into it, then 300 and so forth until i refilled again. btw i had the ac on the whole time and my car is loaded with suitcases and stuff, i would say an extra 150 lbs or so.

 

I had 407 miles at the end and when i filled up i put 15.8 gallons and my gas light was not even on, so i could have gone further, but the next town was a little far and i didn't want to take the chance. i'm sure the nay sayers will find a way to nit pick at this, but the bottom line is i got the mileage out of it. based on how long i drove and how much gas i put back in, that was about 25 miles average. not an accurate way to measure, but the best i can do. have fun driving.

 

i would go nutz driving that slow LOL

 

its not bad if your on a trip... not sure why. i guess just cause you know you can save ALOT of money.. but yea everyday driving slow is very hard to do in a g35...
