Does 2022 lincoln mkz require premium gas

How do you reset the computer? Unhook the battery?

Takes longer than if you use a OBDII reader like OBD MX and FORScan (free software). We're lucky to have that software which is why I sorta stick to Ford and Lincoln for daily drivers.

Under the PCM it's called Learned Octane Ratio. Goal is to have it at 100% for minimum timing pull. FORScan will reset it to 0% when you choose to reset adaptive learning under the PCM.

If you do find true pure gasoline, you'll experience better fuel economy. However ethanol actually allows a engine to work harder since ethanol is harder to burn (and consumes more which is why fuel economy becomes worse). This is why some like to get higher ethanol concentrated fuels like E30 and E89 if fueling systems allow it (the 3.0 MKZ can do this).

Corn makes more power, but real  gasoline allows for better fuel economy.

Hi all. I suspect this has already been asked by someone else, but I couldn't find anything on it. My question is: officially, my 2017 MKZ with the 2.0 Ecoboost runs just fine on 87 octane (regular) fuel. But I also read that "maximum performance" is obtained when it's fed premium. Has anyone here done a comparison to see if it really does perform better? And if so, was it a noticeable improvement? Any help would be greatly appreciated!

Hi 2017. Yes, there are many existing threads on this subject. The minimum fuel octane requirement is 87 octane. The full advertised HP/torque numbers are obtained using 93 octane.

The power difference between the two is generally about ~10%. 89 and 91 octanes will give somewhere in the middle.

Fuel mileage differences are negligible and any small increase using premium is more than lost by the higher cost of premium fuels.

Good luck.

Awesome. I'll try a tank next time I fill up (though unless I feel a big difference, I probably won't continue to use premium. I'm too cheap!). Thanks for your reply bbf2530.

Hi 2017. You are very welcome. Here is an interesting, semi-controlled test by a respected automotive magazine: Is Premium Gas Worth It? We Test High Octane on 4 Popular Vehicles

You can find many others by Googling "regular vs premium fuel" and similar phrases. Try to weed through the "opinion" stuff and find true, semi-controlled, or actual scientifically controlled tests.

In the end, the choice does come down to personal preference as to what is more important. The extra power under your right foot, or the extra money in your wallet.

Also...keep in mind that even more important than octane (remember, 87 octane minimum) is the quality of the fuel we use. So try to use major brand fuels, and use "Top Tier" fuels when possible. The convenience store/bargain brands will save you a few cents a gallon upfront, but they most often do not contain the additive/detergent packages necessary to keep our engines clean.

Good luck.

I have found that 'Top Tier' doesn't mean much.... around here it's just a label.
ARCO (Atlantic Richfield Company) around here has signs that say 'Top Tier' but I know that it's crap gas.

I agree do go for named brands.... 76/Conoco , Chevron, Mobil/Exxon , are what I mean.... LOVES gave me good gas mileage on my trip...

But this is all subjective.... try them all. See what works for you and your driving. 8)

Conclusion for those who may be wondering: I filled up with Premium about a week ago, and have run most of the tank through the car since. My driving style is pretty easy, so extracting max performance is rarely (if ever) necessary. Occasionally I'll put the car is "S" mode (which of course really wakes the car up) to entertain myself, and have been amazed and delighted with the performance they've been able to extract from such a tiny engine. I grew up in the era when "bigger was better", and you weren't a real man unless you had at least 400 cubic inches under the hood! So given that any extra power Premium gasoline may enable is only realized when you're hot-rodding (which for me is basically never), I'll stick with Regular gas.

I'm on my 3rd tank of 93 octane and enjoying the small performance boost. With any more power I think it would need AWD, as the front tires tend to claw for traction on takeoff.

When I had my Mustang ECOboost I ran nothing but premium. I wanted all the ponies I was paying for
One tank of premium isn't going to be enough to re-write the computer.
Besides, if you can spend $50k plus for a car you should be able to afford the extra 10c or so for premium and have fun. If money's tight, fill up at Costco with their visa card and get 4% off
ZOOM-ZOOM.... oops, that's my old Miata ... fun car

What kind of gas does a Lincoln need?

The Lincoln Navigator should be fueled with premium gasoline. This type of fuel will have an octane rating of 91 or higher. Failure to fuel your Navigator with premium gasoline will lead to: Reduced fuel economy.

Can I use regular gas if my car says premium?

In today's automobiles, advances in engine technology mean that even if the owner's manual recommends premium gasoline, the car will typically run on regular without issue and won't damage the engine in any way.
