not even exotics... my landrover takes 94 oct! :O LOL

NO vehicle sold in North America REQUIRES 94 octane. None.

My friend puts in 94 octane in her 2005 Corolla. I laughed......

Would it make ANY difference at all in a Corolla?

Ferrari recommends Shell 91 oct V power gas.

^^ it's actually worse to put 94 in the corolla

what octane should bikes use?
gas SOOOO expensive 1.12?! today
i still cant get over the fact that in dubai its 0.40/litre

My Sentra is bone stock and it pings on 91 :(

My friend told me to switch from 94 Techron to Shell 91 and I'm hooked.

your sentra is just a piece of shit and will ping with any gas in its tank. I would rather take the loser bus than a Sentra.

:werd:

chill dude...

^yeah thats really mean, although my 2003 corolla had over 230,000kms on it and never pinged on 87, so I wonder why the sentra is that way

Maybe he has a very old Sentra that was poorly maintained.

theoretically it's worse.

it's hard trying to explain to people why they don't need to put 94 octane in their civics..

" BUT BUT IT"S FASTER, I CAN FEEL IT "

GM recommends 93 for corvettes

im tuned on 94 ... i require it :p

lol

'05 ser. Perfectly maintained.

Why is it worse anyway? I need to educate her on this so she doesn't toss more money down the drain.

Well I'm no expert on this but i'm sure it has something to do with: The octane rating in fuel represents the fuel's resistance to detonation, that's why some of the higher end cars with a high engine compression ratio needs a higher grade gas so it doesn't detonate too early (knocking). This is the part i'm not sure, but I think if you put in say 94 in a corolla, the fuel will not be lit up at the right time, therefore lowing your performance as well as having left over fuel in your cylinder.

^ yup.

If your car is meant to run on 87 octane, and you put in 94 octane, you will have unburnt gas in there because the 94 octane burns slower.

If your car is meant to run on 94 octane but you put 87, the gas will burn too quickly, and possibly cause detonation (knocking in the engine)

Now, some cars have knock sensors AND are able to advance/retard the timing automatically. For example the Lincoln MKS has hp ratings for regular octane and premium octane. (it's about 10hp difference for that car)

I was talking to the owner of super save gas last week, and we got to talking about "bad fuel" - a few things stuck in my head:

- It's very rare that a gas station's 94 octane isn't 94 octane. If tested, that's the MINIMUM that it must come back as. Most 94 octane fuel leaves the refinery at 97 or 98 octane to make sure that it's still 94 octane 6 months later when tested at the gas station. (the octane starts off real high, then drops fairly quickly, then plateaus)

- So when people complain of bad gas, it's unlikely unless the fuel has been sitting in the ground for a looooong time and / or there is significant moisture in the tank. Most gas stations will not caryy 94 octane if there isn't sufficient demand for it to be used up regularly.

- More common problems related to "bad gas" are water contamination. It's very likely that there is some water in your car's fuel tank - even if you don't think there is any, and even if you have run the tank empty.. there is probably still some water in the valleys and channels of the bottom of your fuel tank. The worst thing you can do in regards to fuel is run your car empty. Always keep a good 1/2 tank of gas in there.

^ plus it saves money to buy the lower octane for a corolla so it's a win win...

thumbs up to you mister ... ive had the botom of the barrel gas from shell 91 and had clogged injectors blah... good way to tell if the gas is getting low at stations is that the pump is really slow compared to normal , when that happens i get the F outa there .



the best is when you see a redneck driving a 86 5.0 rustang throwing 94 in it with nos octane booster ...

I rmb reading somewhere that 94 oct is usually 96-07 oct, where as 87 tends to ship as 87 and go down from there....

Talking about premium gas, I used to put only Chevron 94 in my 328i, then one day while running out of gas (the car was showing 0KM remaining) I went to Domo (too afraid of car stopping on me) and put 10 bucks in their premium (I think it was 92?) and I realize the car feels a lot more of power and roads where I usually do 10KM/L was doing 15KM/L on my console. (I'm pretty sure my driving habits didn't change in any major way, I still press lightly on the pedal)

From there on, I usually get 91 from Chevron but it still didn't feel the same as the one I got from Domo, next time I'm in Richmond, I will be visiting Domo again and see if it was just me..... :D

Learn how to read, he said require....

GM recommnads, but its not needed.
