Fuel
Hey everybody. Just purchased a new 2025 F150 Tremor with the 3.5L and 402a trim. I have kind of a ridiculous question, but coming from owning Ram pickups I’m curious what octane fuel you use. The Hemi engine recommended 89 octane, so that’s what I used and the 3.0L Hurricane stated minimum of 87 octane, but noted better performance with higher octane, but it was so minimal it wasn’t worth the extra cost. The owners manual for the F150 has very similar wording. 87 minimum, but better performance with higher octane. Just curious what others use. With unleaded being over $5/gallon in my area and this pickup having a 36 gallon tank compared to 23 in my previous pickup. Looking to see real world if it’s worth the extra cost at the pump for higher octane in these twin turbo engines. Thanks.
