When Does Your Gas Light Come On
I want to determine just how many miles on average our 8's can drive once the light comes on before you are truly empty. I am assuming that since I got to 265 miles the last time (before my mods), filled up (12.9 gallons) and had 3 gallons left in the tank, that I probably had another 30-35 miles maybe.
What has everyone else been getting?

I notice im my car that when the it gets to E i still have a bit left in the tank, so it might be more like 40 miles for him from light>E, cause no one wants to run the car all the way down to nothing.
I do notice the while my gauge stays very even as it drops (about the same miles for each 1/4 tank) it does get more 'sensitive' as it gets lower. I notice that when im at the point where the light is about to come on, if I accel fast, or go up a hill i can get the light to come on for just a sec till I return to a cruise or flat surface, also right after it has come on if I brake hard or go down a hill it will go off. interesting.
I personaly love the fuel gauge in this car, best ive ever had (this is the 3rd car ive owned, but only one of many ive driven)
here is another thread with similar topic, some of the post also awners the question about when the light comes on : https://www.rx8club.com/rx-8-discussion-3/ode-my-fuel-gauge-68955/

apparently not everyone knows that or he wouldnt have asked. please explain why mielage would go down. one would think that since you have less fuel in the car the car weighs less so your mileage should increase.
see not disagreeing with everything you say. just trying to educate myself.

I'm not referring to less gas mileage when closer to E. I was implying that I could have pushed the car close to 300 miles before I would have been scared that I would have the engine stop. That's not to say that 3 gallons of gas left and 265 miles so far would mean it would go over 300 miles, just I didn't want to push it.
I just wanted to know how many gallons are left in the tank once the light comes on so I can determine how long I have left before the E in my gauge turns to W = Walk.
Looking at the other thread - https://www.rx8club.com/showpost.php...54&postcount=6 it seems that if the light comes on between 245-265 (seems average) then I have roughly 30-35 miles left before I am in trouble. So it's probably safe to assume that at 280 miles I better find a gas station soon. I am going to try this on my current tank and see how many gallons it takes to fill-up when I hit 280 miles. I would have tried it earlier as I just hit 250 miles and was just below 1/4 tank, but the wife took the car out last night for the first time and decided to fill it up for me. Thoughtful but screwed up my theory... oh well.

my experience has been that the light always comes on at about 13 gallons used. i guage this from the fact that after the light comes on and i go tothe stastion i usually fill up with 13.5 gallons. i have gone 340 miles and filled with 14 gallons after travelling for 20- 30 miles with the light one. so mine at least is pretty consistent

yes exactly . i agree . i dont mean to imply she doesnt. her post about etanol was ver helpful.
but anybody that makes statements like the one here or like " brake squeal is usually caused by low brake fluid" should be called on to explain them. if you or i made them several of the more knowledgeable folks on here would set us straight.

I can go 35 miles once the light comes on and have done it many times. I get between 19 & 23 MPG normally without driving it very hard. I let it loose to redline once a drive, usually near the end. Drive on........!!

I HATE all you high mileage chumps!!!!!
My light comes on @ 120 miles which means
I need to get my butt to a gas station fast.
If not, my mpg will be one human power...

I have an AT so I really can't do much "spirited" driving.
I use the highest octane available here @ 91.
My Service Department wants to let one of their monkeys drive the car for a week to check my honesty.... er, I mean, my mileage.
Yea, like thats going to happen...
My lease is up in 10 months.
I'll just sweat it out until then (even with skyrocketing gas prices)
