Ahh, ok. Thanks for the clarification. In that case, I believe Ed Wallace, if I recall correctly always said approximately 12% decrease from same octane E0 to E10.

So 12% easily fits in the 10% to 15% delta.

E10 87 octane up here is 2.50 per gallon. At this price, and a 15% mpg increase, the 93 octane would need to be less than 40 extra cents per gallon for me to even try the 93.
I agree. On my recent trip there were too many uncontrolled variables (moderate to severe weather deltas within the trip) to get a good reading on 91 vs 87.

Isn't the EPA testing on the Focus non-STs done on 87 octane gasoline? I believe for the DCT those are 26mpg and 37mpg, city and highway respectively. While that doesn't mean the 2.0 GDIs don't get 10% - 15% better range with 91 octane, I would think Ford would be hammering "You get a whopping 37 mpg highway on 87 octane gasoline, but if you choose to use 91 octane gasoline you'll get a much improved 42 mpg highway."

If this is truly the case, Ford is dropping the marketing ball on a 160 SAE net hp car getting >= 40 mpg by simply failing to tell the customer to change the fuel octane.

morrjr I'm on my third tank of premium, and the car seems to come alive on the higher octane gas. As long as the premium gas prices stay low (under $3.10 in my area for Shell V-Power, and under $3.00 for generic gas) I'll keep on using premium.

cobrajet429 I drive the same route everyday. After 2 tanks of premium still 36.9 avg. I do notice better response in the lower rpm's. Nothing worthy of 40 more a gallon.

How can gasoline affect the transmission on a car?

And if 93 is all you have run what are you comparing your mpg's to to know they are up? I run ethanol free 87 grade and have seen about a 7% increase in mpg's vs running 87 grade 10% ethanol. And I've put 103,000 miles on my mk3. Ethanol free costs an extra .20 cents up here so it's worth it to me. What are you paying for 93 octane? If it's costing you more than 10% than other gas....well if it makes you happy....go for it;)

But since I have the 5 speed, I don't have 6 speeds :) I also may or may not have red lined it coming out of the few tolls I had to slow down for.
Stopppppp.

You're making me miss the NE. :(
