The Types Of Gas An Acura TL Uses (Explained)

On this blog, we do a lot of research regarding specific questions about different cars. To find the answer, we’ve gone through the owner’s manuals of the Acura TL that were produced from 2013 onwards. Today we’ll look at the Acura TL and answer what kind of gas this car requires. Here’s a quick answer:

Acura TL’s built between 1996-2014 with a 3.5L V6 engine are designed to use premium unleaded gasoline with an octane of 91 or higher. It can also use unleaded gasoline with an octane of 87, but the TL can only use this for a short period of time. 2000-2003 models with a 3.2L V6 engine also use the same premium unleaded gasoline with the same octane of 91 or higher.

However, that doesn’t tell the whole story. Below we go into more detail about the kind of gas or diesel you should use for your specific type of Acura TL. We’ll also discuss if different types of gas are better or worse for the durability of your engine and its performance. Finally, we answer some other questions about the fuel requirements for the Acura TL. Read on!

Fuel Requirements Based On Engine Type

2009-2014

The Acura TL cars made between these years are the fourth generation. The 2009-2014 Acura TL includes two types of engines. One with a 3.5L V6 engine, and the other with a 3.7L V6 engine. These engines are designed to use premium unleaded gasoline of 91 or higher octane rating. It can also use regular ‘high quality’ unleaded gasoline with an 87 octane rating. Anything less than 87 would result in metallic knocking. Similarly, the premium one is highly recommended than the regular one.

2004-2009

The Acura TL cars made between these years are the third generation. 2004-2009 has three types of engines. One with a 3.5L V6 engine, the second with a 3.2L V6 MT engine, and the third with a 3.2L V6 AT engine. Each engine has its own uniqueness. Each engine is designed to intake the same premium unleaded gasoline of 91 or higher octane rating. It can also use regular ‘high quality’ unleaded gasoline with an 87 octane rating. But all three of the engines use the same fuel.

1999-2004

The Acura TL cars made between these years are the second generation. The 1999-2003 models with a 3.2L V6 engine are designed to use premium unleaded gasoline of 91 or higher octane rating. Anything lower than 91 will cause metallic knocking.

1996-1999

The Acura TL cars between these years are the first generation. The models between 1996-1999 have 2.5L engines. These are designed to only intake regular unleaded gasoline with an octane rating of 87 or higher. Anything less than 87 is not recommended.

What Types Of Gasoline Can And Can’t Be Used?

Besides regular/premium gasoline, there is a large variety of different gasoline available in the market. So without further ado, let’s have a look!. We will discuss, Whether or not these gases can be used in the Acura TL.

Reformulated Gasoline

Reformulated gasoline is a newer type of gasoline that is designed to burn more cleanly than conventional gasoline. This means it reduces smog-forming and has less toxic pollutants. RFG is specifically used in areas of the United States where air quality is a problem.

Acura owners would always recommend the reformulated gasoline to avoid any engine problems, particularly the knocking one. It provides excellent durability, considering how the car is being used and on which terrain.

Gasoline/Oxygenated Blends Or E-85

In many cases, fuel suppliers also provide oxygenated blends of gasoline. One of the most popular mixes is regular gasoline with ethanol. E85 is a common example, where 85% of ethanol is mixed with 15% regular gasoline. Cars that can use this mixture normally have fewer miles per gallon but reach higher horsepower and torque.

E85 with various fractions is also known as Flex-fuels.

This fuel may cost less, but you would have to use more of it than the premium gasoline. Car engines that use E85 need specially designed engine parts because regular engines won’t handle this type of fuel and could cause the engine internals to rust. 

To know if a particular vehicle can run on E85, you can take a look at the gas cap. Or you can take a look at the gauge cluster. Sometimes it’s mentioned on the fuel gauge. In the case of Acura TL, however, you can’t use the E85 (flex fuel).

Gasoline With Added Materials

Some types of gasoline have additives to help improve the fuel’s usefulness. These additives can help the car’s engine from getting corrosion and can stabilize certain fuels which are unstable. But it may not always be good for every car.

As for the Acura TL, the gasoline additive recommended is termed “Top-Tier detergent” gasoline. This gasoline is mainly used to help maintain the performance and reliability of your vehicle.

Other than that, this fuel is completely metallic-free and contains the right amount of additives. If you cannot find this particular one, you can use the ACDelco Fuel Treatment Plus instead.

The gasoline additives harmful to the Acura TL contain metals like manganese, which we have explained in the next section.

Gasoline With MMT

Methylcyclopentadienyl manganese tricarbonyl (MMT) is an octane-boosting additive. The use of this gasoline is merely controversial, particularly in modern vehicles. But there is a downside of using fuels with MMT on some cars. The continuous use of this gasoline can cause the building up of Mn-deposits in the engine.

As for the Acura TL, the gasoline with MMT is not advised as it’s known to cause premature wear of the spark plugs and affect emissions. This fuel is only used in racing fuels, completely meant for the track and not for normal use. Any damage that occurs to the engine by the use of MMT will not be covered under warranty.

Biodiesel

Biodiesel is a renewable, clean-burning fuel. It is similar to the ‘conventional’ or fossil diesel. It is derived from biomass, which is plants, algae, and dead animals. It is derived from living materials as well.

As it happens, a variation of the fourth generation Acura TL was rumored to have a diesel engine. But it didn’t happen. So, all-in-all, there is no model of the Acura TL designed to use Biodiesel.

What If I Hear A Knocking Noise From The Engine After Refilling

The owner’s manual has some information about this kind of problem. It is completely normal if it’s a light knocking noise. But if it is a loud knocking noise, it’s a problem you need to worry about. Most of the time, the reason for this is the use of incorrect fuel.

Fuels having less than the required octane rating can cause engine damage, and if used for a prolonged period, loud knocking will be heard. Engine damage due to low-quality fuel will not be covered under warranty. Damage caused by prohibited additives like MMT will not be covered under warranty.

Does the Acura TL Have Good Gas Mileage?

Acura TL does give a good gas mileage, although it’s not considered the best out there. The last TL generation that ended in 2014 has the best overall gas mileage compared with the predecessors. The TLX, however, beats the TL in the mileage game.

What’s The Gas Tank Size Of An Acura TL?

All the generations of this car have different tank sizes, varying from 17.0 gallons to 18.5 gallons. So, the first generation (1996-1999) has a tank size of 17.2 gallons or 65 liters. The second generation (1999-2004) has a tank size of 17.0 gallons or 64.7 liters. The third generation (2004-2009) has a tank size of 18.5 gallons or 70 liters. The fourth generation (2009-2014) also has a tank size of 18.5 gallons or 70 liters.

How Much Does It Cost To Fill Up An Acura TL

When we look at the gas prices, the most expensive gas is being sold in California, and the cheapest gas is available in Mississippi and Texas. The quality is the same. The only difference is the price. How much different? In California, one gallon of regular gasoline is $4.388, while in Mississippi and Texas, that same one gallon costs you about $2.816.

Let’s take an average of 18 gallons. If you are in California, it will cost you $78.98 to fill up an empty fuel tank of an Acura TL. But if you happen to be in Mississippi or Texas, you would only have to pay about $50.67. In a broad sense, wherever you are, the cost to fill up an Acura TL is somewhere between $50-$80. The price varies depending on your location and the gas quality you are going for.
