Types Of Gas A Lincoln MKC/Corsair Takes (Explained)

On this blog, we extensively research your queries about various automobiles. Today, we’ll look at the Lincoln Corsair (previously MKC) and see what kind of gasoline it needs. We looked through the owners’ manuals from 2015 onwards to find the answer. Here is a quick response:

Lincoln MKC manufactured between 2015 – 2019 take regular unleaded gasoline with an octane rating of 87 or higher. Lincoln Corsair manufactured from 2020 onwards also take regular unleaded gasoline with an octane rating of 87 or higher.

Using the right fuel is essential to get the best performance of your car. However, this doesn’t tell the whole story. Below, we will detail what kind of gasoline should and shouldn’t be used in the MKC/Corsair. Furthermore, we´ll discuss this car’s fuel tank capacity and gas mileage. Read on!

What's Inside show

Fuel Requirements Based on Engine Type

As stated, 87-octane gasoline is recommended for both MKCs and Corsairs. It´s important to clarify that this advice holds for the 2.0L and 2.3L turbocharged EcoBoost engines used in both the MKC and Corsair and the 2.5L I4 hybrid powertrain used only in the Corsair.

Since the MKC and Corsair are luxury vehicles, we´re sure many people will wonder if it isn´t a better idea, in general, to fill them up with premium gasoline anyway. However, this is not typically necessary, and it certainly won´t harm your vehicle but will hurt your wallet.

Using premium gasoline when regular gasoline is recommended doesn´t do many positive things for your car in day-to-day use. This is because the MKC and Corsair weren´t designed to use premium gasoline and, therefore, won´t be able to derive many benefits from it in terms of a longer lifespan.

However, there´re instances in which Lincoln recommends premium gasoline with an octane of 91 or higher. One of these instances is when you´re towing since the higher octane level can provide the little extra power needed to make this happen easier. Another situation is scorching weather. Besides these situations, regular gasoline is the way to go.

What Type of Gasoline Can A Lincoln MKC/Corsair Take?

Furthermore, different types of gasoline are and aren´t appropriate to use in your MKC/Corsair. Below, we´ve outlined all these types so you know exactly what can and can´t be used.

Reformulated Gasoline

First, we have to talk about the use of reformulated gasoline. This is a type of gasoline that burns cleaner than non-reformulated gasoline. For this reason, it´s mandatory to use in some regions of the United States.

Similarly to other Lincoln cars like the MKZ or the Continental, among others, Lincoln MKCs and Corsairs can run on reformulated gasoline just fine. If you have the choice between these two types of gasoline, it´s best to go with reformulated gasoline since it doesn´t cost anything extra but does help the environment and the air quality in your region.

Gasoline/Oxygenated Blends or E-85

Secondly, there´re oxygenated blends of gasoline. Oxygenated gasoline blends typically contain ethanol or methanol, both of which are bio-sources of gasoline. Using both of these substances comes with strict rules that must be followed.

First, methanol cannot be used in any model year of the MKC or Corsair. Methanol is a very corrosive substance that will damage the internals of your engine and fuel system.

On the other hand, there´s ethanol which is commonly used in the United States. MKCs manufactured between 2015 – 2019 and Corsairs manufactured from 2020 onwards can take gasoline with a maximum percentage of 15% ethanol. Therefore, E10 and E15 are completely fine to use.

However, E30, E50, or E85 (also referred to as flex-fuel) can´t be used and will damage the engine’s internal components and the fuel system beyond repair.

Addition of Cleaning Agents

The use of cleaning agents or octane boosters is something that you´ll hear about from time to time. Therefore, it´s good to know that Lincoln recommends against the use of these cleaning agents. This is because cleaning agents often use silicones or metallics that will damage your engine’s fuel system and the internals.

Instead, Lincoln recommends the use of TOP TIER gasoline. TOP TIER retailers sell this type of gasoline. This group of retailers is an alliance that provides gasoline that contains all the suitable cleaning agents your car needs and in a larger quantity than what´s stated by law. You can find a TOP TIER gasoline retailer at toptiergas.com.

What If The Engine Makes A Knocking Noise?

If you hear a knocking noise coming from your engine, then it´s most likely the case you´ve used gasoline with a lower than recommended octane rating. That’s far from the worst thing you can put your gas tank but it’s not ideal either.

Also, you could have used gasoline with a higher-than-recommended percentage of ethanol.

You must stop the vehicle immediately and call your dealer or mechanic if you hear a loud knocking noise from your engine, especially right after refilling. Your car needs to be towed away and drained from its gasoline, and your fuel filter will also need to be replaced.

Continuing to drive with a loud knocking noise will result in irreparable damage that is not covered by any warranty.

What’s The Gas Mileage Of The Lincoln MKC/Corsair?

The MKC and Corsair fuel economy aren´t the best if we´re talking about using gasoline only. Expect to reach a combined MPG in the low 20´s. However, Corsair does come with a 2.5L PHEV drivetrain, and if you opt to go for this Corsair, the MPGs increase considerably.

Corsair Fuel Economy

Engine	Combined MPG	City MPG	Highway MPG
2.0 AWD	24	21	29
2.0 FWD	25	22	29
2.3 AWD	24	21	28

This is the fuel economy for the plug-in hybrid:

Engine	Hybrid MPG	Gas-only MPG
2.5 AWD PHEV	78	33

MKC Fuel Economy

Engine	Combined MPG	City MPG	Highway MPG
2.0 FWD	23	20	27
2.0 AWD	21	19	25
2.3 AWD	20	18	25

What Is The Tank Size Of Lincoln MKC/Corsair?

Lincoln Corsair, manufactured from 2020 onwards, have a fuel tank capacity of 11.2 gallons or 42.3 liters. Its predecessor, the Lincoln MKC, has a fuel tank capacity of 15.7 gallons or 59.4 liters.
