Hello everyone, Which fuel is better for the Ford Fusion, 87, 89 or 92 octane gas? And which gas station you prefer to pump gas at?

The first question is easy--87. The others are just a waste of money given the engine design and calibration.
I avoid stations with E10 fuel (i.e. 10% Ethanol), such as Shell & Sunoco, since they contain roughly 5% less energy than 'regular' gasoline and thus cause a drop in fuel economy. If Ethanol were actually cleaner or reduced our dependence on foreign oil, then I would reconsider, but the evidence is not convincing with present processing. I avoid Citco for the obvious reasons. I generally use BP or Marathon.

Hi fuzionblaze! :wavey: The Fusion only needs a good quality 87 octane fuel (check your Owners Manual). Paying for a higher octane will bring no increase in performance or MPG (unless you have retuned your Engine Management System to take advantage of the higher octane).

What I am going to say next is not intended to aggravate anyone, just save you money. A few members will possibly now tell you that they use a higher octane (on a stock engine) and get better better performance and higher MPG. If it were true, Ford could easily recommend a higher octane to get a better EPA rating, and higher Horsepower ratings for the 3.0. Ford does not make those claims with a higher octane, because there are no benefits. The Engine Management System is not programmed to take advantage of higher octanes.

If anyone saw a tangible benefit with any higher octane fuel, it was most likely due to a poor quality 87 octane being used previously.

Again, I do not say this to insult anyone, but if I have my choice between believing Fords Automotive Engineers, or a non-professional opinion (including my own), I will choose the Automotive Engineer every time. They designed the car.

Short story, use a high quality 87 octane (the recommended fuel), and save your money.

Personally, I use Exxon-Mobil, Shell and BP-AMOCO, in that order of preference.

Good luck with your Fusion. :cheers:

I use 87 where ever it is cheap.  I mostly got to Sunoco, Hess, or Stop & Shop if I have a 10 cent off coupon.  Sometimes I go to Gulf.

My gas cap says "Ford recommends BP", so that's all I use. Just kidding! I laughed the first time I saw that. I typically fill at Costco. QT would be the second choice. QT is "Top Tier".

With my car, I have found that Shell gives the best gas mileage and Sunoco the worst. The Sunoco stuff goes through the car like water (I'm guessing because of the ethenol mixture like a previous post mentioned.) Ironically enough, on my daily commute, the Shell station is the most out of the way and the Sunoco is the easiest to get to! :? As for performance, I don't have any proper instruments to test any of this and I couldn't detect any performance variations. I have tried all of the major brands and all of the fuel economy numbers are fairly close and the difference between the Shell and the Sunoco is approx. 1-2 litres/100 kilometers. I only put 87 octane in as per the manual as it is still in stock tune.

Happy driving :csweeney:

I use mostly Marathon which I think is Shell gas. As mentioned above Terry Dyson likes Shell and if he likes it I use it.

I try to stay away from the small corner store gas stations like a mom and pop store. I go to any of the well known gas stations (BP, Chevron, Shell, etc.)

I normally used either Sunoco and Chevron, but by reading this, I think I'll be using just Chevron for now on. What do you guys think about Chevron? Is it better stuff?

Shia, you can't go wrong with Chevron or Shell. I can't remember the last time I didn't fill up on Shell gasoline, but if I was not around a Shell and HAD to fill up, I'd go with Chevron.

18 months and there has never been anything but Shell in it.
