One of the more common questions about the Ford F-150 EcoBoost is this: Does it
require premium fuel? The short answer is no. But, even though it’s not
required, there are instances where premium fuel is strongly recommended.
The
Ford F-150 EcoBoost is a 3.5-liter V-6 twin-turbocharged engine, and using these turbochargers, it is able to provide V-8 power with V-6 fuel economy. With the get-up-and-go, it provides a more pleasing driving experience than a traditional V-8 engine. However, this has raised questions on where that performance come from? The turbochargers. So, wouldn’t it need premium, aka 91 octane or above, fuel to achieve this performance?

Ford F-150 EcoBoost and premium fuel
Ford states in their owner’s manual for the 2022 F-150, the truck recommended fuel type is 87 octane. So, for an everyday drive, regular fuel is just fine. Kind of.
However, even this can be confusing since 87 is often mid-grade depending on where you live. As we discuss in finding the
right octane fuel for your truck, the minimum fuel at a pump, aka regular, can vary from 85 to 87 octane. Premium can also vary between 91 and 93 octane as well. What this means, though, is whether 87 is regular or mid-grade where you live, that’s the fuel you
must use in your truck to stay within warranty.
Speaking of premium, there are times when it is recommended.
The
manual states on page 252, “For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer.”
You seem to be someone with a F150 eco boost. My statement was a general statement not specific to any one vehicle.
Premium is recommended for hot weather or towing. Under most other situations the ecu can adjust just fine.
