sorry if this has been posted. i tried a search to make sure i'm not being repetative, but i didn't find anything.
i was wondering what gas type would be best for the 05? would stepping up the octane to the premieum be better? or is the regular ol' unleaded the way to go.
i've heard high octane on some cars can be more damaging than good, but i don't really know a whole lot on the subject...so i thought i'd ask the pros.
besides the prices sucking royally, i'm just curious. i want to make sure i do what is best for the engine and the life of the car.

No point in exceeding the manufacturer's recommended octane. Higher octane means the fuel will resist early ignition at higher compression ratios. So, engines running high compression will need higher octane to avoid knocking/pinging, which is premature ignition due to the pressure inside the cylinder.

does running plus or premium on occasion, like icwspiker3 said, beneficial? i think i've heard an *old dads tale* that said, "putting in a tank of the good stuff on occasion will help to keep the engine cleaner and running better."
i'm guessing this may be bending the facts a bit...and if putting in the wrong octane gas would make the engine knock and what not, i don't know how it would benefit it. i guess i've heard it is almost like putting in one of those gas additives to you take to clean your fuel injectors or what have you. i personally haven't used any of those yet, didn't know how well that kind of thing worked.

What will keep your engine clean is buying from the gas companies with, well, cleaner gases. Esso/Exxon is one of the dirtiest, and Chevron is one of the cleanest. Not sure about the American gas stations though.

As I said, I'm not sure about American stations. Here in Canada, there is a big difference between the brands. Esso is filthy, Petro Canada is so-so, Chevron is great, and Mohawk is extremely clean - just to name a few.

It really depends...I talked to a mechanic friend of mine, and he said that the real difference is in the additives...some of them actually lower the evaporation point of the fuel, and can cause some problems.
Another mechanic friend told me to only buy gas at the major stations...not from ma and pa shops. I had been having trouble with a check engine light due to an O2 sensor tripping...I switched back to the name brands (I had been using Costco gas) and voila! Haven't seen the light since...I was all ready to change out the sensor too...

newer harleys come with a sticker on em recommeding 91 or better. I just figure it had somethin to do with epa emissions. bikes are real lean from the factory just to satisfy epa.
dont know if octane affects that at all...

There are that many chemicals in our petrol (what with low sulphur, ultra low sulphur, optimax etc etc) that it is hard to know which is best. I think that Shell has one of the cleanest and best performing (hence why Ferrari F1 use them) petrols on the market. I also think that BP claim to have the cleanest as well!

Higher octane gasoline also has a lower BTU output which translates into slightly lower M.P.G., it also is a waste of money.

Here in germany we have unleaded/normal fuel: 91 octan, premium/super: 95 octan and super+/optimax: 100 octan.
has the GT or V6 more power with more octan?
My neighbour drives his bmw 525i with unleaded and sometimes with premium fuel (91/94 octan). He says: "More octan, more power and higher topspeed."

nothing has changed yet, but i'm still hopeful. if it doesn't go off, i'll put in in the shop soon. all it had to do was last until i traded it in on the mustang...what a bummer.
