Report: Don’t use regular in your 2015 Ford Mustang EcoBoost, unless you don’t like power

The 2015 Ford Mustang is being offered with a potent 2.3L EcoBoost turbocharged four-banger, which is a first for the Mustang since the Foxbody generation of the 1970s and 1980s (and boy do we hope to forget about those).

But unlike the original Foxbody turbo-four Mustang, the 2015 2.3L EcoBoost model actually produces power, 310hp and 320 lb-ft of torque to be exact, while being more powerful and more fuel efficient than the base 3.7L naturally-aspirated V6 model.

However, in an interesting find by Mustang enthusiast site, Mustang6G, one has to always use premium 93-octane fuel in order to achieve these power ratings, otherwise, anything less will result in a significant power drop.

According to the site’s findings, the 2015 Mustang EcoBoost will only churn out 275hp and 300 lb-ft of torque if using regular. Now, obviously, the days of fears over engine pinging from using inadequate lower octane fuel are over thanks to knock sensors and engine control computers that actively and constantly adjust ignition and valve timing to compensate, but either way, there’s no denial that different octane fuels provide different power ratings.

So the moral of the story is, if you want to use your new 2015 Mustang EcoBoost to the fullest extent, don’t cheap out on your fuel unless you have to.
