Premium Unleaded?

How big are your blow off valves going to be? HKS? Tial?

It read the manual two years ago and yes your right its like the Raptor, that's why I wrote recommended.

The Escape 2L Ecoboost has a 10-1 compression ratio.
Prolonged use of 87 is not going to be good in the long run.

Ah crap, recommended didn't take on my phone. Fixed it.
I still shake my head when people talk about using the cheapest gas thay can find, it's not a rental folks take care of your stuff.

Also look at page 177 in that owners manual.
Plus not sure if that manual is for the EB high output 3.5L
And if you can use E85, you can't in the Gen1.

Are you sure its actually required on her Escape? This is another one of the engines where the power numbers Ford list under specs was achieved with 93 octane. The owners manual for the Escapes with the 1.5L Eco and 2.0L still states that 87 is the minimum and premium should be used for additional performance.



Ford has done a lot of work making sure their engines can run 87 as a minimum as a premium fuel requirement might deter people from getting an Ecoboost in their next Ford.

My wife currently drives an EB Escape and runs 87 all the time. No issues, if 91 is required, that is a surprise to me.

Here is what I am seeing on both the 2016 Fusion EB and F150 EB: 87 octane, minimum; 91-plus, recommended

Not required, recommended

Higher octane fuel is no better for your engine than plain 'ole 87. Premium just detonates at higher compression, thus reduces knock on high compression / turbo engines. Premium also won't get you better mileage or less buildup on engine internals so long as the detergent levels are the same on both grades of fuel. Numerous tests have proven this.

Harambe prefers premium.

You definitely sound sure of yourself, but what you are stating is not correct. To simply say prolonged use of 87 is not going to be good in the long run and just an ignorant remark. No matter the compression. Any fuel can be detrimental if the engine is not properly tuned for that octane level.

Not sure what you are talking about to the Gen1, but they can easily accept e85??

Yup! The 5.4 was designed specifically to be able to use E85 and according to @Wilson the 6.2 has no problem running the E-30 he runs either. Don't know where dude heard you couldn't use corn juice in a Gen1.

Read your manual!!!!!!!!!!! For the Gen1 6.2L Raptor.
Don't know anything about the 5.4 Raptor
Wilson only uses E30!!!!!!!!!!!!

I've been around the garage for 40 years you do learn somethings in that time.
You go right on ahead and do what you think is best for you.

I sure would like to see those tests.
