2011 Non FFV F150 3.5 ecoboost picked up 62 peak HP and 52 ft lbs torque using E30 of E10.
"Summary /Conclusions
In all cases, non-FFVs tested on a dynamometer using splash blended E30 fuel provided greater horse power and torque based on data collected from idle to wide open throttle.
Use of E30 in vehicles not labeled as FFVs reduced knock retard by 60% when compared directly to E10 in a six tank trial over 40 vehicles spanning in excess of 80,000 miles.
Due to a reduction in knock retard, average mpg on the fleet of participants was not compromised. There was a gain in mpg on four cylinder vehicles using splash blended E30 vs E10. This is not consistent with responses previously reported in EPA certified lab testing using only certified fuels versus commercially available real world fuels.
Service vehicles were found to gain .4 mpg or 5.5% increase in mpg over 107,000 miles traveled on over 14,000 gallons of fuel."
