I did a full fill-up and drove the entire tank empty on a road trip in our former FX4 Maverick using Maverick (ironic) gas station’s “clean-gas/ethanol-free 91” (blue handle pump). I honestly didn’t notice a bit of difference in any capacity.i wonder if anyone has gone with some Ethanol? Alot of plans made for when i get mine landed. immediately under the knife. Trying to finish off 2023 with being one of the fastest mavs on the east coast lol..
from alot of videos ive seen, people claim their butt dyno notice increases in power when going from 87->93/94
I think with the minimal differences with oct switching, its hard to really notice well because A) its minimal and B) the way the PCM handles the power transition through the transmission. which apparently is a downfall on the 8spI did a full fill-up and drove the entire tank empty on a road trip in our former FX4 Maverick using Maverick (ironic) gas station’s “clean-gas/ethanol-free 91” (blue handle pump).

Extra power from Premium on most vehicles is barely noticeable. On my supercharged Mustang, going from 93 octane to E85 is good for over a 150HP increase. Even with the 25% loss of mpg, it is well worth running, and the fact that E85 is cheaper is a sweet bonus. Obviously there are some benefits to running premium on the Maverick, but it would be much more noticeable powerwise with a tune.Only if you want the extra power. Last month my math says it costs me 11.1 cents per mile with 87 & 12.2 cents per mile with 91, so it's not a huge difference, but if you have to count pennies then yes it's not worth it.
