Ecoboost engine question
With the Eco doing so well and loved by many and bragged about by Ford. Why is it not offered in the F250 ? I love mine but I'm curious.

I think premium simply allows the engine to produce more power. The high compression caused by boost lets the EB efficiently take advantage of higher octane fuel. I don't think it has to burn premium, but it is a case where it pays off in performance. FWIW, my old 5.0L Mustang also suggested premium for better performance, but I never used it. The DWs Corvette demanded premium, and that is what it got.
I think the Ford ecoboost has a detonation sensor because it could detonate if the computer had no way to know it was starting. But with the sensor, the fast computer can reliably compensate and the EB can precariously run at max just under the detonation threshold.
I have owned an Ecoboost a hair over 4 years and 69,900 miles now. It's the car version in a Taurus SHO.
The EB will definitely run perfectly fine in all conditions on regular gas. That's what I have been feeding mine all this time. Been in the freezing cold, 100+ heat of TX, LA, FL and never an issue. Sometimes under a heat soak and wanting max power you can feel it not working 100% smoothly but it will still pull like crazy. This year I played around with 89 during the summer and she smoothed out well. Premium still is the smoothest ride and you can feel it work a little better but I get no more fuel economy so I don't run it much.
The EB will most definitely detonate given the right circumstances. Some of us with early builds of the car engine had knock sensors that would chafe and cause erroneous readings. I had 2 incidences of rather violent knocking before they replaced the sensor @ 30k. Sounded like you were shaking a can of Krylon in the passenger seat.
It definitely is a fine engine.
