They should be made unbelievably delicate and light, so if the crash into a wall they form a fist sized ball of tin and don’t hurt anyone. THEN they can push the limits to the extreme of how fast something can go.

Some people rest their laurels on principal and principal alone, misguided or otherwise.

Thank you for the link, and the knowledge. I knew about the different levels of gasses, I didn’t know the different testing methods that altered the vehicle output. Its surprisingly pedantic considering the different conditions and driving usage a vehicle can be subjected to, but it’s good to know where they derive…

I could see that, as I have no idea the appeal of a 3 and I love most cars. People seem to swear by them and even after vocalizing their appeal I fail to see it. 500cc dirt bikes are kind of the same as well.

Sorry I’m having a bit of trouble understanding what your saying. I get the higher loading of the cat, but is the engine in US cars on a different warm up cycle than Euro? And by aggressive do you mean more fuel added during that time or less?

Mmmmm. Yes I’m sure that’s true and not some nonsense you just made up. Because that’s what FI forums are filled with, regional comparison of gas. Especially when the octane levels are calculated in the same way. I guess the engines the Canadians use to test gas are just that much more compliant, huh.

Well if that’s true you wouldn’t need a bigger catalyst, you could just turn down the boost to limit combustion tempatures and produce less NOx, since the only real difference is they allow a little bit and the US allows none.

Through the comments here I have determined 91 is a West coast thing and 93 is a East coast thing.

You can actually put regular in most cars today, turbo or not, and it will run fine for a tank or two. But they tune factory cars to run optimally in the most common conditions found in the market, so they would tune it to run better with lower grade fuel, its just safer for the engine, think if the knock sensor…

91 at most stations in:

Well its good to know since I was planning on driving over there and the trips to Cali and Portland were plagued with retarded timing and lack of power. I guess I can drive my nice car out east with less worries of that sort.

So FIAT should design two cars, one for the east and one for the west of America?

I assumed you’re an American because you came off like a defensive asshole trying to wage leverage on an argument using vague terms that you can quickly back out of. AKA “Trumping”. But seriously, say something or fuck off.

Well whoever runs that station should open up some over on the west coast, I never saw a single pump over there with more than 91.

Also, did you even look at that chart? The gas you used an example of is their equivalent of “regular unleaded”, their “superplus” and Shell Vpower is all 93-94.

Depending on the composition of the fuel, the MON of a modern pump gasoline will be about 8 to 12 octane lower than the RON, but there is no direct link between RON and MON.

American gas is shitty compared to Canadian gas. Chevron pumps have 94 ethanol-less handles. It can be hard to find 91 in some states. 98 RON in Europe, which most stations in Germany pump, is around 93 AKI. When was the last time you saw a 93 handle, oh superior American?

I live in the country north of you. We can pump 94 ethanol-less gas from Chevron pumps. We use the same fuel classification system. I have a hard time finding 93 and sometimes even 91 in some states when I road trip.

So the question is, where are you buying 93 in the States? Its not offered at every gas station, I have had a hell of a time finding it in some states when I road trip down there.

If that were true then the MON of that same gas is 84, pretty unlikely. If the RON is 98 its more likely that the AKI or octane is around 93. So good fucking job on showing me up. There is no correlation between RON and AKI, you need to know the MON, which is determined by aromatics and additives, its different for…
