Premium Fuel

[70NYD]

Use whatever fuel they tell you to.. Anything more and it's pointless, unless the timing is self advanced absolutely untill knock

That's what my Evo currently drinks so this won't be a problem. Glad I could actually find this topic though so I didn't have to create one!

Could you be any more ignorant? The octane rating has nothing to do with hurting the environment. And ethanol production has been shown to be harmful to the environment, nevermind that ethanol contains less energy than gasoline and thus reduces the fuel mileage of vehicles. The ONLY benefit to ethanol being added to fuel is to (barely) reduce the US's dependence on foreign oil.

i wonder why can't they make ecu to adjust whatever octane we want to use...

this car will be daily driver. don't need to spend almost $4 a gallon everyday...

because thats not how it works.. look up how it works, then come back and explain how it is possible to use ANY octane rated fuel, without loosing power/efficiency

I'm upset that they can't design a engine that will run on regular, diesel and/or hamster pee. Very frustrating.

In all seriousness, this car is tuned for performance. If you want a car for fuel economy there are many other options. The cost of premium fuel over a year is negligible especially if this pulls over 30mpg hwy.

I still want more than 30mpg Highway.

Maybe I should just buy a prius for school. And be a baller when I go to work and the grocery store. Lol

Edit: Or.. that new Mazda CX-5.

[WolfpackS2k]

I wouldn't worry about that. My S2000 tops 30mpg on the highway quite regularly. This car should get 34-35mpg on the highway easily.

I'm a little skeptical if premium fuel (91-93) will improve mpg, but octanes above 93 definitely won't help (nor are cost effective). I'm waiting on the EPA ratings but it this thing can get 35 highway, I will be very pleased!

for example genesis coupe. horsepower might go down but you have more money in your pocket.


you sound like you have money to burn dude~

You'll also have more money in your pocket if you buy a cheaper car.

i think hes referring to the fact that the compression ratio is so high. there are a lot of things an ecu can fix but cr isnt one of them

Dude premium would be like an extra $150-200 bucks a year ($3-4 a fillup).

Uh dude? You're trying to over-simplify and misinform on a highly controversial subject in 100 words or less. It's not going to happen like that.

Besides, you completely misunderstood what he was talking about. He wasn't talking about Ethanol that's for sure.

It's not a universal statement. It really depends on the engine compression ratio, timing, and propensity to knock. Honda engines which are pretty knock resistant are tuned to handle up to 100 octane RON from what I understand. I believe the difference between Premium and regular is around 3% better efficiency. 3% more power is a big deal, never mind 3% more MPG at the same time.

I have heard that BMW did a study on the effect of using Premium vs Regular in engine design. I'm usually to interested in other subjects but I should look for that study someday.
