I drive 600 to 700 miles a week . 560 mile are hwy. I bought a k&n filter a few weeks ago and it helped 4 or 5 mpg otherwise I'm stock. I get 420-460 miles a tank with about 2 gallons left in tank all hwy . I usually am over 100mph on hwy too. City usually 80 mph + i get anywhere from 260 -340 a tank.

Cold air intake coming soon.

 

I'm lucky to get a bit over 300 in my 04 6mt.. what is this sourcery you speak of?

 

gettin labove like 350 or so is near impossible if you drive alot city. with darn stoplights and traffic. i think 400 is easily attainable if the majority is highway miles

 

got an 06 6mt coupe with z tube
i suppose maybe tires matter too so i'm running 255/35/19s front and 275/35/19s rear

i drove from los angeles to vegas and almost half way back to los angeles with a total of 3 people in the car and a full trunk. cruise control on for about 75% of the time @ 80mph. there were times i punched it up to 140mph during the drive. got 453 miles. when i stopped to pump it filled up to 18.2 gal so there are more miles to be had.

check out my mpg
suck it toyota

 

I usually get about 200 miles at half tank mark. Not sure if I actually use 10 gallons but will try to fill up at 1/2 tank next time to find out.

 

Some things I noticed about my G(had it for 2 weeks)
It's an 04 6MT with 22k miles and a fresh air filter.

Whenever I fill up the needle barely reached the top notch on the gauge.
From the point when the low fuel light comes on to the being full takes around 15 gallons, I don't know if that's normal.

The fuel economy itself is OK but not great, I usually shift around 2.5k RPM and don't beat on it too hard. Last 2 tanks I got 19.5 miles per gallon driving a mix of 60% highway and 40% city.

I calculate fuel economy by dividing the number of miles I drove by the number of gallons I filled up.

 

i cleaned my dirty a$$ K&N and filled up the tank....drove from LA to Vegas, drove around vegas, and made it back to Barstow before i had to fill up again......

when the fuel light came on, i had driven 440 miles......but at fill up, i was only able to put 17.5 gallons of premium in....

not too bad on gas!!!!! i dont have any engine mods btw...just a K&N

 

oh yeah, i forgot to mention i was averaging 75-80 mph both ways, with an occasional ***mph!!!!

 

Back up!

Question guys how long do you guys drive before the gas light comes on?

I had the E' light come on and i have 385 miles on the 17 gallons i put in which my car considered to be full.

With that said, is our tank really 20gallons? Are the remaining 3 the 'incase ****' happens gallons?

If so, how deep are you guys driving with the gas light on? I havent even hit 400 and the gas light is on.

2004 G coupe BTW.

 

Or live in Los Angeles

 

I have ran the with the gas light on for about sixty miles one time and when i filled up i put in a little over 18.5 gallons

 

i got 313 miles on a tank of gas, and didnt run it dry so i could have gotten more

 

75 or 80 mph up and down hills? That's pretty fast

 

If I wait for the light to come on I have over 400 miles a tank, usually don't wait that long though...

Worst tank mpg was 18.5 when I spent about 50 miles driving at an HST event. Averaged 8 mpg at the event and a lot of highway trying to bring the rest of the tank average back up!

 

Wow, my car must not be a G35 then. I get average 240-260 per tank. Best Ive ever had was 310 on a tank, once. I dont drive like a pu$$ but also not like im at at the drag strip. Idk what im doing wrong here...
