What type of fuel do you usually use in your car?

I have a 2020 Fusion SE with the 2.0L EcoBoost and AWD. Just passed 101k miles. It’s running fine, no issues, but I’ve noticed when I use 87 octane, it feels a little rough. Ford says premium is recommended, but I don’t really want to use it all the time. I usually go with 89 octane, and it seems to run smoother. What do you guys usually use?

If it feels rough on 87, there might be an issue. These cars should be fine with 87 normally.

It’s not a big issue, just a noticeable difference. Ford does recommend premium for this engine.

Most cars say premium is recommended, but they’re still designed to handle 87 without problems.

If it says premium is recommended, you might want to stick with it. Using lower octane means the engine won’t perform as it’s meant to.

Higher octane will give the 2.0 a bit more power, but if you’re using a good brand of regular gas like Shell, you should be fine.

I stick to 93 premium but only fill up small amounts at a time, usually less than half a tank, and always from Costco. It’s just a couple of bucks more per fill-up. I’ve noticed my MPG might be slightly better, but honestly, it’s mostly for peace of mind with the 2.0L engine. I haven’t seen a huge difference in how it drives between 87 and 93, though.

I always go for premium in my Titanium. The 2.0 EcoBoost seems much smoother on it.

I just use 87 in my 1.6. No issues so far.

Ford says 87 works fine, but if you want a bit more power, higher octane can help. Stick with good-quality fuel and you’ll be good.

I switched to Shell 91 V-Power Nitro+ after using 87 and 89 for about a year. I had issues with misfires and changed coils and plugs a few times. Once I switched to premium, the problems stopped, and it’s been about six months now. Might be a coincidence, but I’m happy to pay a bit more for peace of mind.

The 2.0L with a turbo is designed to work best with premium. Running 87 is okay short term, but over time it can lead to problems like carbon buildup, lower MPG, and more repairs. The money saved on cheaper gas now might be spent on maintenance later.

I use 93 in both my 2017 1.5L and my 2018 2.7L.

I’d stick with 93 octane, especially when it’s hot outside.

I use 95 premium (European fuel rating) for my 2.0 EcoBoost. Occasionally, I’ll add octane boosters or go with 100 octane. It runs great, and I also clean the injectors with Techron now and then.

I’ve been running Shell 87 in my 2014 Fusion 2.0 EcoBoost and other family cars without issues. My old Focus ST manual said you’d get about 10 more HP with 93, but I never noticed a big difference.

I use E15 in my 2014 2.5L. Works fine for me.

I usually stick with premium.

Turbo engines do better with higher octane, but Ford’s system adjusts for lower octane if needed. You’ll lose some performance, though. I always use 93 in my Sport.

I just use regular gas most of the time.
