87 vs 89 vs 93 octane - my findings

[LokiWolf]

Those specs also claim 20mpg for the 5.4l. Yeah, I don't think so. Page 2, just says 320hp, not 320 using E85

Read the fine print...you know those little numbers. You can learn a lot...

I get 20 MPG all the time with my 5.4 on the highway cruising. It’s got 2 overdrive gears in a 6 speed dude.

Good for you dude. Must have the lame-o 3.08 gears and drive like a granny.

And there’s the @rjdelp7 we all know and love. When his “facts” and “info” fail...he starts insulting the Expeditions he doesn’t own.

Extended Length models have 3.73s. 6R has two overdrive gears and lockup clutch function in all forward gears 2-6. Saves gas, improves performance. But yeah, it’s just lame-o, dumb, and I’m a douche.

You said it, not us.

 

[rjdelp7]

Can the Eco Boost run E85(or Explorer). The 5.0l Mustang doesn't. I don't think the Shelby can run it. Corvette and Dodge Hemi don't. Strange, if it makes more power. Edmunds did a test of E85 and declare it's a total failure on almost every level.

You did buy a 5.4l 3V...

No, the EB’s cannot run full E85 without a pump upgrade or tweaking the tuning. Technically you can run full E85, but the tune has to be turned back, you get more HP, but less Torque than say E50.

Turned fully up, E50 is the max on the EB Expeditions can run without a Pump upgrade like the ones from XDI.

The pump is the limitation. Flow has to be faster, and you max out the Pump, before you reach full power potential.

Willing to mix...the power advantage is there. I mix 93 and E85 to get to E50 on my Explorer.

I believe it. The question is at what speed? I'm guessing 65 or less.

 

[Jeremygsu]

On my Explorer 93(E10) gets me to 4.06 0-60, same environment, E50 gets me 3.75 0-60. No other differences in hardware.

Your Explorer does 0-60 in less than 4 secs? That's better than a C7 Corvette.

Yep, 2020 Explorer ST, E50 tuned by ZFG.

That's nuts. Is this an AWD?

Has to be. Couldn't hook up and pull that time without AWD. Tires would just spin.

My HD tow EL 4x2 is geared 3.31. It's in the tow guide and confirmed using the axle code.

They all have "overdrive", that means nothing, plus 6 speed doesn't affect highway MPGs either. You might have the best gears in that truck in final drive for MPGs but taller gears don't automatically mean better MPGs. One step higher ratio than that could diminish your gas mileage. It's the final drive that counts on the hiway so 6 speeds and 2 OD's has nothing to do with anything here.

The 5.4 was never mated with 3.31s in the EL models. 3.73 was the only option 07-14 but 3.31 became available on 2WD models for the EcoBoost. 4WD EL EcoBoosts are also all 3.73.

You are clueless lol

Huh? That is exactly what Overdrive’s are designed for!

Yes, under certain circumstances lugging in too high an overdrive can decrease MPG, but on flat ground OD increases MPG.

IF OD’s did not help with MPG, why does the 10Spd have additional? Even on the 5.0...

Moving on.
