StevenCaylor Posted November 27, 2012 Share Posted November 27, 2012 But the Focus ST puts out the same power using 87 octane IIRC then 93...I don't see Ford requiring 93 for the Festia ST But the Focus ST puts out the same power using 87 octane IIRC then 93...I don't see Ford requiring 93 for the Festia ST How can you "require" a fuel that isn't even available in most of the country?

Deanh Posted November 27, 2012 Share Posted November 27, 2012 How can you "require" a fuel that isn't even available in most of the country? Ibeleive in certain countries their 93 is the same as our 91........ Quote Link to comment Share on other sites More sharing options...
Deanh Posted November 27, 2012 Share Posted November 27, 2012 93 octane. and less mass to move Equals greater ablity to load the engine. BTW 34mpg, too. actually not sure thats correct, all the 1.6 ecos ( and 2.0 for that matter ) are rated at their peaks with 91 octane ( equivilant to 93 overseas ) I think theres more going on internally to raise the roof ( boost/ cam profiles, ECU ) Quote Link to comment Share on other sites More sharing options...
papilgee4evaeva Posted November 27, 2012 Share Posted November 27, 2012 Ibeleive in certain countries their 93 is the same as our 91........ On this coast I've seen 91 octane exactly twice. Both times in the same area (near Glen Burnie, MD). Everywhere else I've been, 93 is premium. Quote Link to comment Share on other sites More sharing options...
OHV 16V Posted November 27, 2012 Share Posted November 27, 2012 (edited) The Midwest and the East get 93, or in some cases, 94 octane. Out West and in Cali, 91 is the normal high. It's been this way for a long time. The reason for this is that "in higher-elevation areas, a typical naturally aspirated engine draws in less air mass per cycle because of the reduced density of the atmosphere. This directly translates to less fuel and reduced absolute compression in the cylinder, therefore deterring knock." Turbocharged engines in the past have typically had trouble producing their power peaks in these higher-elevation areas, even at an octane rating of 91. Obviously, technology has advanced. That's why the Eco engines are rated to produce their power at 91, but can still run fine on lesser-grade. Look at it this way, if you have access to 93 or 94..."the more the merrier."

fordmantpw Posted November 27, 2012 Share Posted November 27, 2012 91 is premium here in MO. There are no pumps around with 93 octane. Quote Link to comment Share on other sites More sharing options...

The Focus ST with an ECU tune and nothing else is putting out 272hp, or 136hp per liter notice the defined drop in HP at 5300rpm as the ECU pulls off the boost. With the 1.6 in the fiesta ST the engine is developing 125hp per liter the same as the 2.0 GTDI in the Focus ST the 1.6 in the Fusion and Escape are only putting out 112hp per liter. either Way it is entirely possible to boost output simply with the ECU, and because the vehicle is lighter it reduces the load on the motor providing a extra margins for the tuners to get more power without destroying engine durability and more importantly emissions.

SoonerLS Posted November 28, 2012 Share Posted November 28, 2012 The Midwest and the East get 93, or in some cases, 94 octane. The availability of 93 is, as far as I can tell, driven by elevation, not region (with the possible exceptions of "special" cases like Kahleefohneeya). Around here, 91 is premium and 93 is exceedingly rare, but if you go ~150 miles south to Denton and the Dallas Metroplex, where you drop around 600' in elevation, premium is 93. If you go out to El Paso (and rise ~3200ft above Denton), 91 is premium again. 1 Quote Link to comment Share on other sites More sharing options...

This is exactly what is making me contemplate buying the 6-speed 1.6L Fusion and then applying the Fiesta ST or equivalent tune to the motor to make slightly more power. I'm not looking for insane amounts more, but I'm sure it could be applied relatively easily. There is a sweet spot between the 2.0L and 1.6L that I bet could be achieved through a little work. I wonder if the Escape and Fusion 1.6L and 2.0L EB are also held back for MPG reasons as well as the durability/emissions situation in general.

My regional statement was a "generality," because, that's mostly the case, but not always, because elevations can differ so much within any given region. Appreciate the help. 1 Quote Link to comment Share on other sites More sharing options...

If you go out to El Paso (and rise ~3200ft above Denton), 91 is premium again. I'm at sea level and we only get 91. And wouldn't higher elevation require higher octane anyway? There is less atomspheric pressure up high so the engine (in theory) could knock more often. You compensate that by using higher octane. I honestly thinks 91 vs. 93 octane is mainly due to the regional refinery specs that supplies the gasoline in your region. The specs are dictated by the crude oil they can buy. For example, all the west coast refinery get the crude oil from Alaska and it is more expensive to get the Alaskan oil to higher octane due to surphur content. On the other hand, "Texas Sweet" from the Gulf of Mexico has low surphur and you can get 93 much easier/cheaper; thus the southeast has 93 octane.

Biker16 Posted November 29, 2012 Share Posted November 29, 2012 Automobile says the ST could get as much as 34mpg... Sounds low. 50mpg for the 1.0EB? Sounds a bit high. Ford says 34mpg not the magazine, it is a performance model after all, not the fuel miser. 50mpg is too high, the fiesta's aerodynamics aren't good enough for that.

There is less oxygen at higher altitudes so that reduces the octane requirement. Quote Link to comment Share on other sites More sharing options...

Biker16 Posted November 29, 2012 Share Posted November 29, 2012 the specs page from ford list the fuel at 93 octane, I suspect they meant 91 octane in the US. Quote Link to comment Share on other sites More sharing options...
