What fuel do you use?

[2020-MAX-Limited]

Regular Unleaded. Since we are above 5,000 ft in Colorado, our Regular Unleaded is 85 Octane. Don't tow, don't hammer it; in fact, just baby it. Never had an issue with knocking or any engine/drivetrain glitches.

The 2022 Expedition Owner's Manual states 87 Octane is the recommended fuel. See page 197. Interesting! I run 87 in Phoenix. No problems.

Because our driving is pretty much limited to running around in town, we run on 87 Octane, but we always buy top tier products which have the same amount of additives as the higher Octane versions. If we were going to drive under conditions that require a higher octane (towing, mountainous roads etc.) we would use the higher versions. Granted ours has low mileage, but so far, so good.

I live rurally so if I am staying in town or around the area I will use 87. If I plan on traveling I switch to 93. Without a doubt 93 is what it loves based on acceleration and shifting. All the gas in my area contains ethanol except for a few stations near the marina. Since purchasing always ran gas with ethanol.

There used to be a show on the radio called Click and Clack, the Tappet Brothers. They were humorous, but I thought they were very well informed, both graduating from MIT.

They always claimed that it made no difference between regular and high test gas. I've been running regular with ethanol in 4 of my Expeditions with no issues. They still have had plenty of power, even pulling my 9,000 pound trailer.

I even run that same fuel in my 1981 Yamaha 650 with no issues.

I was running 87, but it seemed to stubble or hesitate some. Went back to 91 and it runs better.

The manual says 87, "for best overall performance...91 or higher is preferred". Somewhere, perhaps the brochure, it states to get the 400 hp in the platinum, it needs 91.

And not to beat this dead horse, you do know gas is gas, right? From some one who loaded and hauled it for years and years, it's all the same. Out of the same pipeline, out of the same tank, out of the same trailer. It doesn't matter if it's Costco, Shell, QT or Sunoco....it's the same. IF additives are put it, it's at the terminal and it's AT MOST, 1% of what's in your gas. Buy it on price point from a busy store. Don't fall for "mines better than yours", or it runs better on brand X. It's all the same...this is FACT.

Click and Clack, the Tappet Brothers

Ahh, yes, Click and Clack. Funny, smart guys. I just don't know anymore. With all these turbo and supercharged engines, more and more manufacturers are requiring premium. Do they really know something (Tom's been gone for almost 10 years, the shows been off air for almost 12 years), or has time pasted click and clack and technology has changed and premium is required?

Try this (I ain't wasting money on 93 octane.)

Is Premium Gas Worth It? We Test High Octane on 4 Popular Vehicles

We tested higher octane fuel than manufacturers require on the Honda CR-V, BMW M5, Ford F-150, and Dodge Charger to see if it impacted acceleration or MPG.

Interesting and kind of what I expected. I'll continue to do what I'm doing, which is run the truck on 87 when driving locally and on 93 when towing and / or taking long trips.

Have been using Costco 93 octane on all my Ecoboost trucks for years. More power, better fuel mileage and they are Top Tier rated.
