Fuel Requirements Based on Engine Type

As stated, 87-octane gasoline is recommended for Aviators that are made from 2020 onwards. On the other hand, the older generation prefers 91-octane gasoline. This is common in some vehicles, including the Lexus RX350.

Since the Aviator is a luxury vehicle, we´re sure many people will wonder if it isn´t a better idea, in general, to fill up current-day Aviators 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 current generation of the Aviator wasn´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 very hot weather. Besides these situations, regular gasoline is the way to go.

What Type of Gasoline Can A Lincoln Aviator Take?

Furthermore, different types of gasoline are and aren´t appropriate to use in your Aviator. 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 Aviators 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 Aviator. 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. Aviators 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

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. 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 Aviator?

For many, it won´t come as a surprise that the Aviator wasn´t focused on fuel economy back in the day. Therefore, the 2003 – 2005 edition of this SUV achieves a combined MPG of 13, with a city MPG of 12 and a highway MPG of 16.

Luckily, the new generation of the Aviator does much better. These days, the Aviator makes use of a 3.0L twin-turbocharged EcoBoost engine. You can have a gasoline-only version or a plug-in hybrid. The gasoline-only version gets a combined MPG of 23, which still isn´t fantastic. However, the plug-in hybrid can achieve a combined MPG of 56, which is quite impressive for an SUV this size.

What Is The Tank Size Of Lincoln Aviator?

Lincoln Aviators manufactured from 2020 onwards have a fuel tank capacity of 18 gallons or 68.1 liters. On the other hand, the 2003 – 2005 Lincoln Aviator has a fuel tank capacity of 22.5 gallons or 85.2 liters.
