Miles per Gallon
 

HOLEY SHITE! :Eyecrazy: THIS CAR SUCKS GAS!!!!!!

You may know, I have a pet peeve against how-many-hp-will-my-intake-give-me threads, white-goo-on-my-dipstick threads, and synth vs. dino threads, but particularly fuel mileage threads. I hate them.

Nevertheless, I just started my car over the weekend after a LONG stay in the garage. There was still 3/4 of a tank left in the car (I did NOT add stabilizer, but I did add some octane booster for that residual gas.) I have driven for 3 days now AND HAVE VISITED THE GAS STATION TWICE!!!!!! The last tank gave me 15ish mpg.

I think I am going to go back to driving my frigging Chevy Silverado for my daily. I can get 16 mpg if I overfill the tires and I have a 23 gallon tank, so no daily trips to the station.

friggen gas mileage. friggen gas mileage thread.


PS. as an actual contribution to general MPG knowledge, I have done a preliminary experiment varying the air pressure in the tires of my truck and on the RX8. I have noted that small changes in air pressure in the voluminous tires of my truck have a significant effect on mileage; in the range of 0.2 mpg/psi. This means that going from a low 33 psi to a normal 38 psi (in the truck tires) nets me one extra mpg. The low profile tires of the RX8 seem to be immune to this effect. I note no significant difference in mpg over a range of pressures from 32-40 psi. I may continue to collect this data through the summer (now that I am driving the car again) and see what I see.

Did you factor the cost of new tires in to the math at all?
Over inflating tires makes them wear in the middle only.

Carbon, what the hell? Of all the people starting a mileage thread.....

What kind of gas are you using? I'm working on a hypothesis that ethanol content has a large impact on RE mileage and I need some data. Shell V-power 91 has no ethanol content so try some and report back... Most other brands seem to have 5% to 10% ethanol.

shell 91?

hmm...ive never seen 91, but the Shell 93 that i only use has 10% ethanol

Keep your foot off the gas and you'll get 18 to 22 mpg.

Yeah, I know. I am going to have a hard time being an ass on the next one that gets posted, but I'll come through.

Dont worry; I'll come through.
:spank:

So gas. Well, as I understand, here in MD we all have 10% EtOH by law. This started last summer, if I remember. Before that, I was getting 17ish mpg in mixed (city/hwy) driving. On the highway, I would easly get into the low twenties. I fill up at a Cheveron around the corner and at shell stations in the area, when I am out and about. 'Bout a 60/40 split, respectively. If I go out of the area, I hit branded stations, BP/Exxon/Texaco, but this is rare. Always 93 octane. Turbo safe.

Dont take my low mileage to heart yet. It is too early after restarting the car. Plus, I can't help hitting the gas. I will calm down soon, my LTFT will set in, then I will start my log. We will see and I will let you know by PM (or this thread if I feel like stirring the pot.)

I guess the no-ethanol thing varies by region or it's just Canada.

So you answered your own question...........

Damn government regulation.

I love my 8.

I try to use Shell 91 V-Power whenever possible- I have actually noticed the best fuel mileage with it. I can't remember the ethonal content right now.....

Transam Kid: octane ratings vary by region. In AZ and Cali, the highest octane rating fuel we can get is 91 (street legal at least). But when I lived in Pittsburgh, I could get 93 octane. It varies due to state laws reguarding emissions

I boo this thread

Come on! you can do better than that! WHERE'S THE PIE? I would tear this thread a new one had I not posted it.


I am curious why no one has mentioned anything about my theory regarding MPG, tire pressure and tire volume. Here:

I entitle the following equation Carbon's MPG tire pressure proportionality theory, or CMPGTPPT for short.

d(MPG)/dTP=some constant*TV dTP, where TP is tire pressure and TV is tire volume. So here as tire volume approches zero, tire pressue has a smaller and smaller effect on MPG.

It's not the same. Part of the enjoyment is watching noobs get all bent out of shape. Don't get me wrong, you suck for creating this, but it's just not as fun.

If you fill your tires to 78psi you can get 39mpg in the RX-8. True story!

:yelrotflm

I hear helium in the tires helps.

Good job!:cwm27:

Damn carbon that sucks. Maybe you should take your own advice.

1) go to the dealer.
2) go up to the manager
3) place your keys in his hand.
4) ask for your money back.
5) go buy a honda cause you don't deserve to drive an RX8


There how was that? Pretty good flame?

This was your post to me when I questioned the MPG on the 8. You (of all people in this forum) have nooooo buisness posting a MPG thread. :spank:

Another way to look at it :
Driving the 8 really makes you appreciate a 2L 4 banger for the great mileage you get ...........

:ylsuper: PUSH IT :ylsuper:

:rofl:


I need a boomarang smilely where the boomarang comes back and smacks me in the head :fight:
:lol2:

that was pretty darn funny. and, carbon, you were a good sport about having it come back at you.

search you f8cking noob!!


ahh, I've always wanted to say that. Now I'm off to cry about the injustice of it all.


hhmmmmm . . . .

hahahahahahaha
