Such bad mileage!!

As far as me driving my FR-S, getting decent gas mileage and having fun, last week we drove 600 miles, including going over 3 mountain passes, on twisty roads (no freeways) and averaged 32 mpg.

Yep, going a bit faster than the speed limit ....... and having a bunch of fun ......

Now, what about this double efficiency thought of yours ..... ??

Wel im just comparing two vehicles. Ive built 10 jeeps in my life. Most of them burly rock crawlers. Not made for any sort of fuel efficiency. Im in canada, forgive me for not making conversions, in my WORST jeep, a gas guzzling pig. 4 tires and rims probably weighed 600 pounds. Extremely low geared 5.13s. Top speed of 86km hr. Gas prices are the same, id pay 76-80$ for a tank and id get around 350-400 km per tank. With my twin. 50$ to fill up and i get around 350-400km per tank. A STOCK jeep with 2000 less pounds gets around 12-14 mpg. Why in the hell would a big old jeep get almost the same as a brand new 4 cyl car? Id expect the car to be waaaaaaay better. I dont expect to get 1000 miles to a tank but i expect to double the kms for dollars. I actually tried to drive liie a grandma, shifting at 2200, never being aggresive. For a whole tank. It was stoll SHIT mileage. It makes no sense that i wouldnt. I almost feeel the mpg display on my frs lies to me.

The displayed MPGs on the dash trip computer is also generally off if you're using E10. Use Fuelly and log your miles/gas for an accurate picture of your mileage.

I have headers and a tune, and even after lightweight wheels and a CF driveshaft I'm averaging 23-24MPG, commuting about 24 miles a day. If I baby it I can still get 30-31 on the freeway doing 60, usually more like 27-28, but seriously, who drives these cars like that?

Drive like there's an egg between your right foot and gas pedal, shift early, coast often and downshift (in other words, drive like a septuagenarian) and you'll get stock mileage. If you've been hammering the gas reset the ECU, maybe check the air filter and the alignment, and buy some RTV to patch the hole in your wallet.

28.5-29.6 mpg mixed driving rural city and hwy 101. 2014 6 spd manual. It finally stabilized after 13 fill ups.

TRD intake/exhaust lowered my mpg by 3. I'm happy with it.

A decent tune will improve that, and the power as well. Changing the intake usually requires a tune to realize the full benefit, if any, and you shouldn't be losing MPG from that.

I ask again how is $76 to 80 (weird choice of numbers) for 350 "the same" as $50? That is a 50% difference. And again that is not factoring in the difference in price between regular and premium.

Also how the hell does 12 to 14 mpg be equal to 24?

Math appears to be beyond your abiliy. You have no concept of reality do you?

YIKES ...... @Norinradd ....... I don't know where to start.

You are using too many different methods of measurement, with too many variables, for me to make since of what you are saying.

What kind of gas mileage (expressed in miles/gal or litres/100 kilometers) are you getting with your jeep and with your twin .. ??

I suggest you not trust your on board mileage calculator to give you an accurate reading.

Hate to break it to you math professor but 50% of 75$ isnt 50$.

Its fine. I just expected better mileage out of a lightweight NA 4cyl.

50% of $50 is $25. $50 + $25 = $75. Ergo, $75 is 50% more than $50.

Well, I wasn't surprised at my FR-S's gas mileage ........ since my Miata got about the same mileage ......

And once again total inability to grasp a simple grade 4 level concept.

I give up since you oviously do not comprehend a thing people say to you.

If you think 24 mpg out of a 2.0 liter engine is bad: http://www.fuelly.com/car/mazda/rx-8...arakawa/392021

There is a lot more to consider than the amount it costs to fill the tank and the distance driven between fuel ups to determine how efficiently an engine makes power. There are also some flaws in using only that, unless the driving environment and cost of gas per liter were identical in both situations. That's not even getting into power output or fuel delivery, as well as countless other variables I'm too lazy to list.

If you're not happy with the current efficiency in your FRS, flash it back to stock and be sure to keep the Primacy (or comparable low rolling resistance) tires. If you're still not getting comparable efficiency to others with a stock car, there may be an issue with either the car or driving technique. If you're not happy with the average fuel efficiency others are getting for the engine displacement and power, research your next vehicle more carefully prior to purchase.

Ergo 50% of 75$ is $37.50

You really need to get a life tcoat. Get your veteran bum ass off the couch, stop feeling sorry for yourself. Its your fault you went to fight a bullshit war for your corrupt owners. Youre on these forums 160 hrs a week.

Or stop trolling my posts. I could give a fuck about your opinions let alone this clear aching you have inside you to belittle people from behind a screen. Get the fuck out.
