Fuel Quality and MPG

[23OBX2.7]

I'm sure many know this. but thought I'd mention huge impact grain derived fuel has on 2.7 for this who don't

For the last year switched to Chevron 94 after Mobil 1 stations dropped 93 octane. Was getting terrible milage in Mustang and Bronco 2.7 so switched to Shell Red Label 93 this week.

What a huge difference. 30 % better economy and drives way better.

Mentioned it to a buddy and he pointed out the Chevron is grain derived fuel and it has been know to ruin high end cars.

Good to know about Shell Red Label 93. I use mostly Country Mark 93 octane, and my Bronco (which has the ProCal tune) loves it. Also had good luck with Sunoco 93 octane. I average 23 mpg on the 2.3L MT.

I'm using Costco 93 and get consistent 21 MPG with a 2.7

Hmm... interesting

My fillups are mostly at Chevron and Valero. There are only a handful of Shell stations nearby though. I try really hard to stay away from anything else when I can help it.

But I never thought to try to clock if there was a difference between them. I'll have to pay more attention.

Wouldn't that just be... ethanol? Which they usually disclose the E-number (around here it's usually E10 or E15, same as most all the other stations). True that more ethanol will tank economy - it only has about half the energy content as petroleum based gas. But they blend it because it's cheap, it provides additional knock resistance (the Octane rating - that's why you see a lot of the Tunes requiring some blend of E85) and for emissions.

I've not noticed any appreciable difference regardless of where I fuel up the Bronco. Most fill-ups are either at QuickChek or Shell, with 2 out of every 10 being at Exxon or Mobil.

I always run 93 and continuously average just over 16mpg regardless. 2024 Wildtrak. Always in Sport mode and 2H. I don't drive it like a racecar (that's what my other toys are for) but I don't baby it either. Only performance mod so far is an AFE Momentum GT intake.

In Canada its mystry fuel just lime many products haha but its drives way better now.

I've noticed a marked improvement in MPG since running ethanol free 91 in my 2.3.

I normally run Shell or Exxon 91.

Obviously you just use maple syrup and Molson in your gas tanks.

That is interesting, someone else here was tracking their mileage and they noted a singificant reduction in MPG when going ethanol-free.

Not saying you or they are wrong - just interesting to note.

Where I am in Colorado you don’t find many name brand fuels. I run 87 in my 24 2.7 Wildtrak. I’m getting any where from 20.5 to 22.4 hand calculated.

I have no idea what's in the fuel I believe regulations require 10% min ethanol for all gasoline pretty sure the octane booster additive makes all the difference.

Cannot speak to Canuck fuel, which is generally not sold in the same gallon-units we use, nor even the Bronco since mine is still being built.

But, I've long had noticeable increases paying extra for ethanol-free. I've even gotten close to 40 in the Spider on the 91EF from Buc-ee's. They also have 86. Increases were also noted in my now-departed F-Type. There was a price to be paid though...

In California all fuels have min 10% ethanol. Thank you corn industry lobbyists.
