A Guide to the Honda Civic’s Gas Types [EXPLAINED]

A Guide to the Honda Civic's Gas Types [EXPLAINED]_1

There are only so many automotive icons that can give you the trinity of bulletproof reliability, fuel-sipping efficiency, and limiter-bashing ecstasy like a Honda Civic could.

However, even the most ironclad of built Civics can start to falter when the wrong type of fuel finds its way into their VTEC-powered cylinders, let alone a completely stock one.

Hence, this is the ultimate gas-type guide to avoid being greeted by a certain knocking sound on your Civic while also not blowing several dollars more on high-octane gas as if you own an Accord!

What kind of gas does a Honda Civic take?

Honda Civic models made between 2001 and 2024/present are designed to take regular unleaded 87-octane gasoline. 

However, Honda recommends using at least premium 91-octane gasoline for the Si and Type R models for optimum performance.

Honda Civic GX models can only take compressed natural gas (CNG).

What kind of gas does a Honda Civic take_1

Given the Honda Civic’s popularity and well-known reputation for reliability and efficiency, it’s no surprise that the majority of its models can take your regular 87-octane gasoline from the pump.

That is, however, if you opt for the lower or “non-performance” trim models for each generation, such as the 1.7-liter “D17A” of the 7th-gen Civic or even the 11th-gen Civic’s turbocharged 1.5-liter “L15B”.

For more sporty Civics like the “Si” and the top-of-the-line “Type R”, on the other hand, Honda advises using at least 91-octane fuel, which puts you in “premium” territory, for peak performance.

But as far as compatible gas types for the Honda Civic are concerned, there’s more to it than just the octane number you can see on the pump.

As we progress through this guide, we’ll also be tackling other important info about the specific types of fuel blends, additives, and what you should and shouldn’t be using out of them for your Civic, so stick around for that!

Honda Civic Fuel Requirements by Generation and Engine Option

Most 7th-gen to 11th-gen Honda Civic models require at least regular unleaded 87-octane gas, with Si and Type R models recommended to be filled up with premium 91-octane gas for optimum performance.

The 7th and 8th-gen Honda Civic GX trims require compressed natural gas (CNG) for their engines.

Keep in mind that most of the engines listed in this part are for Civic models only sold in the US/North American market with the addition of some models sold internationally as well to give a more general idea of each generation’s engine options.

The 7th-gen Honda Civic was made between 2001 and 2005 with three different choices of engines, one of which doesn’t drink your typical liquid gasoline.

The base 1.7-liter “D17A” 4-cylinder engine powers the DX, LX, EX, and HX trims with unleaded 87-octane gasoline being the minimum fuel required for it.

A version of the same engine was made to run on compressed natural gas (CNG) and was only fitted on the GX trim.

A hybrid 1.3-liter “LDA” I4 engine was also offered starting from 2003 under the “ES9” code, which was also designed to run on regular 87-octane fuel along with its electric motor.

For the 2006 model year, the introduction of the 8th-generation Civic also completely revamped the previous gen’s engine options.

Aside from the distinct differences in styling to the last gen, the 8th-gen Civic replaced the old 1.7-liter engine with a larger 1.8-liter “R18A” I4 that makes 140 hp and runs on 87-octane gasoline.

The R18A also serves as the base engine for this generation’s “GX Trim”, which is designed to take compressed natural gas (CNG).

A more powerful 2-liter “K20Z3” engine is fitted on the Sporty “Si” trim, while the “K20A” powers the top-tier Type R model sold in Europe, Japan, and some parts of Asia.

Both of these K-series engines can be run on 87-octane fuel at minimum, but premium 91-octane fuel is recommended to unleash their true performance potential.

On the more fuel-efficient side of things, a 1.3-liter LDA-MFA I4 hybrid engine was also offered in sedan form and also designed to run on regular unleaded 87-octane gas.

The 8th-gen Civic also offered a 2.2-liter turbo diesel option that was only sold for the European market.

The 9th-generation Civic entered the scene in 2011 for the 2012 model year as an updated platform both in terms of styling and choices of power plants.

A newer version of the 1.8-liter I4 called the “R18Z” is equipped on the lower to mid trim levels of the 9th-gen Civic, more specifically the DX, LX, EX, and EX-L coupes, and DX, LX, HF, and EX sedans.

Every one of these trims fitted with the 1.8-liter engine is tuned to run on 87-octane gasoline just fine. However, the GX trim, which also uses an R18 engine, runs on compressed natural gas (CNG) like its previous-gen counterpart instead.

The older K20A from the 8th-gen Si was replaced by the bigger and torquier 2.4-liter “K24Z” I4 for the 9th-gen model, and while it can run on 87-octane fuel if needed, you’ll be getting the most out of the engine when using at least 91-octane instead.

This goes the same way for the “FK2” Type R introduced for this generation in Europe and Japan, which now sports some forced induction (a turbo, basically) to boost its “K20C1” I4 motor to 306 hp when filled up with premium 91-octane (95 RON) gas.

The hybrid sedan model was also fitted with a slightly bigger 1.5-liter “LEA-MF6” I4 while still maintaining the same 87-octane requirement for its fuel.

Similar to the 8th gen, the 9th-gen Civic was sold with “i-DTEC” diesel variants equipped with either a 1.6-liter N16A turbo I4 or a 2.2-liter N22B turbo I4 for the European/UK market.

1.6L N16A1 Inline-4 (I4) Turbo Diesel (European/Indian Market Only)Diesel Fuel

A brand-new 10th-generation Honda Civic was released in 2015 with North America being the first to get its hands on the popular Japanese compact car.

Available in aggressive 2-door coupe, 4-door sedan, and 5-door hatchback body styles, the 10th-gen Honda Civic “FC/FK” was offered with a new turbocharged 1.5-liter “L15B” I4 as the smallest engine.

Despite being the first factory turbocharged Civic engine not carrying the “Type R” badge, the L15B only requires unleaded 87-octane fuel to make every bit of its 174 horses.

However, this is assuming you don’t have the Si (Sport Injected) trim, which has a more performance-oriented 205-hp version of the same engine. While you can still run the usual 87-octane just fine, premium 91-octane fuel is where it’ll really shine.

A 2-liter “K20C2” naturally-aspirated I4 is also available for the 10th-gen model that is designed to take 87-octane fuel. Even with the increased displacement, the lack of forced induction makes it have the least power of the bunch at 158 hp.

But if you were really looking for a powerful Civic that you can unleash on the twisties while having all the modern comfort and tech, then the FK8 Type R with the same 2-liter K20C1 turbo I4 carried over from the previous gen will fit the bill.

With 306 hp (316 hp for the European and Japanese markets), the Civic Type R FK8 can properly stretch its legs when fed with at least premium 91-octane fuel since it was tuned to run optimally with such.

Of course, there’s the additional diesel option in the form of the same 1.6-liter N16A “i-DTEC” I4 turbo diesel, though once again, it’s only available in select markets, specifically in Europe and India.

2.0L K20C1 Inline-4 (I4) Turbo (Civic Type R)87-Octane Gasoline (Regular) (91 Octane or Higher Recommended)

The newest Honda Civic “FE” or “FL” (sedan or hatchback) model marks the 11th generation of the popular Japanese econocar with optional “go-fast” bits.  

While it arguably has a slightly more subdued and “mature” look than the 10th-gen model, the 11th-gen Civic actually has a lot in common with its predecessor once you take a look under the hood.

For starters, we still get the same 1.5-liter L15B 4-cylinder motor for half of the trim levels, albeit now providing about 180 hp, a 6 hp increase over the last model. 

The good news is that you still don’t need to spend extra on premium, as 87-octane fuel is all that it needs even with the slight bump in power output.

The same goes for the 2-liter K20C2 non-turbo I4 on the FE2 Sedan and FL2 Hatchback, both of which retain the same 158-hp power output and 87-octane minimum fuel requirement.

The 11th-gen Civic Si gets a new 200-hp “L15CA” turbo I4 motor, and like previous Si engines, it can run on 87-octane fuel as needed but prefers premium 91-octane fuel to perform better.

Even the newest Civic Type R on the market, the “FL5”, is capable of running on 87-octane fuel with its upgraded 316-hp (325 hp in Japan and Europe) 2-liter K20C1 I4 turbo motor.

But of course, don’t expect to make that peak power output unless you fill it up with at least premium 91-octane gasoline, which is what Honda highly recommends for the most powerful Civic ever to roll out of its assembly lines.  

Types of Gasoline/Fuel That Can Be Used in a Honda Civic

The Honda Civic is compatible with fuel such as TOP TIER detergent gasoline, up to 10% or 15% ethanol blends (E10/E15), and compressed natural gas (CNG) for GX trims.

All gasoline blends compatible with the Honda Civic must have a minimum octane rating of 87 to avoid engine knock and damage. 

TOP TIER Detergent Gasoline

TOP TIER Detergent Gasoline_1

As far as recommended gasoline blends go, the majority of manufacturers, including Honda, endorses TOP TIER gasoline for its engine-cleansing detergent additives.

Compared to other gasoline brands that may vary in terms of detergency levels, gasoline formulated according to TOP TIER’s standards has a higher detergency concentration, making it one of the most recommended fuels for your engine.

Through such detergent additives in TOP TIER fuel, your engine will be well-protected against the buildup of carbon deposits and any debris that may impede its performance and even cause damage to its components over time.

This makes TOP TIER detergent gasoline highly recommended for the Honda Civic, especially for the more recent models starting from the 9th generation onwards that have more advanced engines and fuel systems.

With over 60 US fuel brands adopting the TOP TIER formula, it’s a fairly common gasoline blend to see. Just be sure to look for its signature green logo/label (as illustrated below) and choose the recommended octane for your particular Civic model.

TOP TIER Detergent Gasoline-2_1

Up to 10% or 15% Ethanol Blends (E10/E15)

Up to 10% or 15% Ethanol Blends (E10E15)_1

The majority of today’s gasoline contains an oxygenate called “ethanol” that is blended for its octane-boosting benefits, renewability, and lesser carbon emissions. 

Based on ethyl alcohol and derived from corn and other suitable grains, ethanol is mixed with gasoline in several different “blends”, the most common ones being “E10” (10% ethanol) and “E15” (15% ethanol).

When using ethanol-gasoline blends on the Honda Civic, in particular, it’s important to mention that not every model year or generation is compatible with the same ethanol percentage. 

According to the owner’s manuals of several Honda Civic generations, models made from 2001 up until 2013 are compatible with up to 10% ethanol in gasoline (E10).

In contrast, 2014 and newer Civic models are equipped with fuel systems that can take up to 15% ethanol blended in gasoline (E15).

Be sure to take note of these limits depending on your particular Honda Civic generation and model year, as using gasoline with too much ethanol can corrode and damage your engine and fuel system components.

Cars like the Honda Civic that are limited to only 10% or 15% ethanol can be classified as non-FFVs (non-Flex-Fuel Vehicles), and will thus be equipped with a regular black gas cap instead of a special yellow one for FFVs.

Compressed Natural Gas (CNG)

Compressed Natural Gas (CNG)_1

Aside from the typical liquid gasoline that most people are familiar with, a limited amount of Honda Civic models are equipped with special fuel systems that can run on compressed natural gas (CNG).

Such Honda Civic models capable of running on CNG are the “GX” trims of both the 7th-generation and 8th-generation Civic, which are powered by the 1.7-liter “D17A” and 1.8-liter “R18A” respectively.

Going by this, instead of the usual 12.4 to 13.2-gallon gas tanks that most Honda Civic models come with, the Civic GX models are equipped with smaller 8-gallon tanks instead. 

 Types of Gasoline/Fuel to Avoid for the Honda Civic

Avoid filling up the Honda Civic with gasoline containing MMT, E-85/Flex-Fuel, any fuel with over 15% ethanol content, or gasoline with a lower octane rating than 87.

Honda doesn’t mention using reformulated gasoline (RFG) for the Civic, so it’s best to avoid it for now to be on the safer side.

Gasoline Containing MMT (Methylcyclopentadienyl Manganese Tricarbonyl)

Gasoline Containing MMT (Methylcyclopentadienyl Manganese Tricarbonyl)_1

Regardless of your Honda Civic generation, the Japanese car manufacturer strongly advises against using gasoline containing the fuel additive “MMT” due to its known downsides.

MMT has been used as an octane-enhancing additive in both leaded and unleaded gasoline for decades. However, MMT is known to be very toxic to the environment when emitted out of your exhaust.

Honda also states that using MMT or any manganese-based additives, in general, can negatively impact your vehicle’s performance and fuel economy. It can potentially cause your malfunction indicator lamp (MIL) to turn on as well.

In addition, MMT is also notorious for prematurely wearing out your vehicle’s catalytic converter and fouling its spark plugs, making the trade-off with MMT just not worth the risk.

E85/Flex-Fuel and Ethanol Blends Higher than 15%

E85Flex-Fuel and Ethanol Blends Higher than 15%_1

Since we already learned that the Honda Civic is only capable of taking gasoline containing up to 15% ethanol at most, this means that the use of E85 or “Flex-Fuel” is completely off-limits for the Japanese compact car.

In general, there hasn’t been a single Honda vehicle that is compatible with E85/Flex-Fuel, at least not from the factory. 

E85 can contain up to 85% ethanol and only 15% pure gasoline, and it together with other higher ethanol blends such as E20, E25, E30, and E50 is incompatible with and can corrode the Civic’s fuel system.

As mentioned earlier, one of the main differences between a Flex-Fuel vehicle (FFV) and a non-Flex-Fuel vehicle is that the former is equipped with a special yellow fuel cap that can have “E85” printed on it, while the latter only has a regular black one.

E85Flex-Fuel and Ethanol Blends Higher than 15%-2_1

Reformulated Gasoline (RFG)

While many major car brands and models sold in the US are compatible with reformulated gasoline (RFG), Honda does not mention using it in any of the owner’s manuals for the different Honda Civic generations.

Despite reformulated gasoline’s known benefits of having a cleaner burn and reducing toxic emissions, Honda’s non-inclusion of any guide for RFG signifies that it’s best to stay away from this type of fuel until otherwise stated. 

Does the Honda Civic get good gas mileage?

The Honda Civic has always had a good reputation for fuel economy across all its generations, with the newer 11th-gen models capable of achieving a gas mileage of up to 33 mpg (city) and 42 mpg (highway) with the 1.5-liter turbo I4.

Honda Civic Gas Mileage Per Generation

The Honda Civic has a combined gas mileage of 29 to 41 mpg (2001 to 2005), 23 to 42 mpg (2006 to 2011), 31 to 44 mpg (2012 to 2015), 25 to 36 mpg (2016 to 2021), and 24 to 36 mpg (2022 to 2024/present).

Honda Civic CNG models have a combined gas mileage of 28 MPGe for both the 7th and 8th generation.

Frequently Asked Questions (FAQs)

Does the Honda Civic need premium fuel?

The Honda Civic does not require premium fuel as it is designed to run on unleaded gasoline with a minimum octane rating of 87. 

However, Civic Si and Civic Type R models are recommended to be filled up with premium 91-octane gasoline to the best out of their performance-focused engines.

Is the Honda Civic available in diesel?

There are Honda Civic diesel variants offered for the European market and other select markets internationally, such as the 8th gen’s 2.2-liter N22A2 diesel, the 9th gen’s 1.6-liter and 2.2-liter i-DTEC diesel, and the 10th gen’s 1.6-liter N16A1 diesel.

What type of gas does a Civic Type R need?

The Honda Civic Type R requires gasoline with a minimum octane rating of 87, but Honda highly recommends using at least premium 91-octane gasoline to get the best performance out of its turbocharged K20C1 engine.

Why do I hear a knocking noise from the engine after refueling?

If you hear a knocking noise after refueling your car, then you may have put in the wrong type of fuel, the fuel octane is lower than what’s required for your engine, or the fuel has been contaminated.

In addition, engine knocking sounds may also be caused by issues with your air-fuel ratio or ignition timing, which is why it’s recommended to have it properly diagnosed by a mechanic as soon as you can.
