Overall, 94 octane appears to be $1 more than 87 which sells for $4.58 (CDN) a gallon. 91 would be $5.45 and 94 would be $5.58. Keep in mind that our gallon has 20% more volume than a U.S. gallon. These are converted prices that I read at the Petro Canada (Sunoco) pumps yesterday. As you can see, there is little difference between 91 and 94 octane.

I might try a couple tanks of 91 just to see if I notice any difference but like I've mentioned before, I'm very happy with the current performance.
That is a huge difference, even taking into account the imperial gallon to US gallon. If I didn't drive so many miles per year, I would think stronger about premium. Still may try it for a few bucks a tankful just to see if I notice anything that would be worthwhile.

For premium top tier fuel, go to Costco; as their prices is generally lower than most gas stations.
Right now Costco 91 is at 108.9 and the Shell down the road is at 121.9Totally agree with Costco. Filled up at Costco last night. Just got the 87 though.

So in the end what octane should we use in our 17
Sports
Really it's what ever you want. Try a few tanks (probably 3) of each to see for yourself. If you require or want top performance, premium is recommended. The HP and Torque numbers advertised by Ford were achieved using 93 octane. I find 87 or 89 gives me all I want/need.So in the end what octane should we use in our 17
Sports
My '14 SHO and '16 and now '17 Explorer Sports were filled with 87 at the dealer. 93 made a marked difference after two full tanks of replenishment. Ultimately I added a performance tune which make it a wonderfully zippy ride. Cold air intake on the '16 definitely made a difference when full open throttle, despite claims they aren't effective at lower RPM. My '17 just doesn't reach the full power potential at high RPM like the '16 with CAI. The sport model has a turbo for a reason and should have appropriate octane or why would you buy it? Go limited or XLT with appearance package if you just want darker body parts. Torrie at Unleashed Tuning may be able to provide you with the dynos you're looking for if you haven't realized how much 1/4 mile time you make up with better fuel. If you can't observe the improvement without a dyno, maybe something is wrong with your vehicle.I would like to see a dyno test as well
I could really feel the difference on my explorer sport & my SHO before the reprogramming with the Livernois tune
Have not tried the Livernois 87 octane tune verses their 93 octane tune
The Platinum also has the same engine and is the main reason I have that engine. The MKT also had it and ran just great with 87. Lots of get up and go. I'm not at all interested in 1/4 mile or speed times as that is not what I got the vehicle for. Lately I have been running 91 in the Platinum and it seems to have brought the MPG's up a little but not in a way that it offsets the extra cost of the gas. To each his own.........

Mileage for me wasn't the priority obviously, I just love the GTDI. presently with my tune I have to put 93 in, but have the option to program for 91 if not available. For a everyday standard configuration I still did the premium, despite the cost, I felt like i was losing out on the potential.

There is information online that suggests first gen 3.5l Ecoboost engine have more timing chain wear (single) vs 2nd gen 2016 later production to 2019 (dual) with less wear contributing to what you are stating. If it's in warranty that dealer may be stalling to get you out of warranty because it's a big job to repair replace engine. Just a thoughtI have posted two two recent threads on here about issues with my 2015 sport I recently purchased acting sluggish and having all kinds of power issues. The first time the dealership said it was probably bad fuel and that I SHOULD use either 89 or 93 octane gas. I told them that I had been putting 89 but I would then try 93.
I ran several tanks of 93 octane and the car still had issues.
I just took it back to the same dealership and they now tell me the mechanic noticed the lack of power and said he found it was running 3 times as high in octane as it should be. They then told me to use only 87 octane and to never use anything higher again. They said after a few tanks it should start running better. The mechanic said had I kept running at higher octane "I would have burned that engine out".
I'm no car expert and I feel they are giving me the run around. I know the 3.5 ecoboost is designed to run on all 3 grades of gas and I feel even if this helps the problem, it is just putting a bandaid on the issue as there is still something not right with the engine not coping with the higher octanes it is supposed to have.
Those who have far more knowledge on this forum than me, please chime in, as your responses are going to help me decide my next phone call to this dealership, as I'm not real happy. Thanks.

Thanks Peter, he may have been experiencing timing chain wear related performance issues. By now it's worked it's way out. A rattling in cold starts, idle changes have been noted on an Ecoboost forum. I have 2016 platinum with 92k miles, so far so good we don't drive it much now. Still runs strong on 87. F250 gets distance duty runs.Welcome to the Forum.
FYI, the member you responded to was last seen here on July 28, 2018. Seeing he has a 2015 Explorer I doubt he would have any warranty unless he bought an ESP. Perhaps your post may be of help to others.
