Best Oil for Honda Accord in 2021: High Mileage?

Why Get The Best Oil for Honda Accord?

The Honda Accord is a vehicle that may be found almost anywhere in the United States. It is one of Honda’s best-selling models worldwide as an all-arounder.

If you’re searching for the best oil for Honda Accord, this guide will tell you everything you need to know.

You’ll discover everything you need to make the right decision, from a model overview to user recommendations based on their own experiences.

Whether you simply follow the manufacturer’s suggestion or go by what’s popular, make sure to read every section to learn what works for your specific model and year.

Factors to Consider For Honda Accord Recommended Oils

For most owners, the best solution is to go with what the manufacturer recommends. The recommended engine oil for the Honda Accord may differ depending on the generation or even specific models. As a result, it is essential to consult the owner’s manual for your individual vehicle.

If you have an older model and don’t have the owner’s manual, check for one online. Alternatively, you can look at what other people have been utilizing (more on that next). According to the owner’s manual for the 2010 Honda Accord, Honda recommends the Honda Genuine Full Synthetic Motor Oil.


The manufacturer recommends SAE 5W-20 for the 2010 Honda Accord. It only specifies one viscosity and provides no alternatives. The manual also indicates that synthetic oil can be used, implying that conventional oil can also be utilized.


The four-cylinder engines need 4.2 quarts of fuel, whereas the V6 engines use 4.5 quarts. So you’ll just need one 5-quart bottle of motor oil.

Oil Specification

Aside from the 5W-20 viscosity, Honda requires that the oil be API-certified. It also suggests Honda Motor Oil 5W-20, the manufacturer’s own oil. You can, however, substitute any comparable from any other brand of your choice.

Top Rated Oil for Honda Accord based on Mileage

Because the Honda Accord has been around for more than three decades, most owners with high-mileage vehicles should take it into consideration as well. Depending on the mileage and condition of the vehicle, you may require a slightly different viscosity or specific high-mileage variations.

Regardless of mileage, the most popular oil brands for Honda Accord are Mobil 1 and Pennzoil. Users appear to trust this brand regardless of the year of manufacture or mileage on the odometer.

Some owners claim that semi-synthetic (synthetic blend) engine oils can be used in low mileage Accords, particularly those from the previous two generations, as long as you stay to the prescribed viscosity (0W-20).

So, based on user recommendations, here’s what we know about low-mileage and high-mileage Hondas, since Honda officially makes no differentiation based on mileage.

Low Mileage (Below 75,000 miles)

  • 5W-20 semi-synthetic or full synthetic
  • 0W-20 semi-synthetic or full synthetic

High Mileage (75,000 miles or above)

  • 5W-30 full synthetic
  • 0W-20 full synthetic

Although conventional oil can be used in Honda Accords with over 100,000 miles, the optimum oil for a high-mileage Honda Accord is a 100% synthetic or a synthetic blend. Most manufacturers claim that switching from conventional to synthetic will be easy. However, at the end of the day, it is all up to you.

Important Note: If your high-mileage vehicle has engine difficulties such as leaking, you should utilize High-Mileage variations of complete synthetic oils. Such oils are intended to avoid and combat such problems in aged engines.

To find the best motor oil for Honda, look for one that fulfills API SN, ILSAC GF-5, and ILSAC GF-6 criteria, as well as Honda motor oil approvals. We recommend ILSAC GF-4 motor oil for older Honda models.

1. Castrol Edge 0W-20 Advanced Full Synthetic

The Castrol EDGE 0W-20 is our top pick for the Honda Accord for several reasons, including the fact that it is a group IV full synthetic oil that is API certified for gasoline engines and authorized for GM dexos1 Gen 2. The best news, though, is that Castrol EDGE is the least expensive oil on our list.

Viscosity loss (thinning) due to shear is one of the most challenging difficulties that oil makers encounter while creating motor oil. As a result, Castrol engineers decided to take a risk and infuse the EDGE 0W-20 with Fluid Titanium.

At first look, this may appear to be yet another gimmick, but that is not the case. Castrol engineers conducted x-ray studies on highly compressed engine oil and discovered that Titanium molecules reinforced their bond at high pressure. Because Titanium molecules tighten their bonds under pressure, the oil thickens and provides a cushioning effect, effectively resisting viscosity loss due to shear.

If all of that technical jargon bored you, here’s the major takeaway: Castrol EDGE with Fluid Titanium improved oil film strength by 30% when compared to oil without Fluid Titanium. This is especially essential because motor oil 0W-20 is already one of the “thinnest” grades available.

Another advantage is that Castrol EDGE with Fluid Titanium has been demonstrated to minimize friction by 20% when compared to lubricants that do not include Fluid Titanium. And it makes sense: the Fluid Titanium-infused oil thickens in high-pressure lubrication spots, such as between valves and camshaft lobes, and then returns to its free-flowing form once the pressure is relieved.

The thick concentration is made up of completely refined synthetic molecules. The best engine oil for Honda Accord provides more lubrication strength. To maintain the intended efficiency, cleanliness must remain at its peak. The fluid has a 42 percent higher rating for preventing deposit accumulation.

As it happens, superior output instantly outperforms conventional and blended choices. The less wear, oxidation, and breakdown, the greater the mechanical activity. It reduces unnecessary gasoline consumption, improving total fuel economy.

This motor oil is API certified for gasoline engines, which Honda requires for use in the Accord. It also fulfills or exceeds industry requirements such as API SN PLUS/ API SN, ILSAC GF-5, ACEA A1/B1, and is GM dexos1 Gen 2 licensed (very important for turbocharged engines).

Finally, we have nothing but good things to say about the Castrol EDGE 0W-20. It’s a real group IV full synthetic engine oil (which is quite rare) that has been authorized for the most recent GM dexos1 Gen 2, which means it has excellent high-temperature resistance.

Surprisingly, it is also very affordable. You don’t need to spend a lot of money to keep your Honda Accord in good condition; the K-series engines (which are most likely under the hood of your Honda) are not picky and are quite reliable. As a result, Castrol EDGE 0W-20 is our top choice.


  • Increased system compatibility
  • Excellent lubricating film strength
  • High resistance to damage
  • Transformation under pressure
  • Improved fuel economy
  • API SN PLUS/ API SN, ILSAC GF-5, ACEA A1/B1, GM dexos1 Gen 2 licensed


  • No extending spouts

2. Mobil 1 Extended Performance 0W-20 Full Synthetic

There isn’t much to say about Mobil that hasn’t already been stated — they’re an absolute giant in the oil industry, having been studying and manufacturing synthetic oils since the 1960s. Numerous oil analysis studies have been conducted since then by customers and automobile enthusiasts, and these have only served to underline the fact that Mobil 1 family lubricants outperform the majority of competitors.

At the time of writing, Mobil 1 Extended Performance 0W-20 Motor Oil was prepared with a proprietary combination of high-performance synthetic base stocks and a balanced additive package that meets or exceeds the requirements for the hardest and most recent API Service Categories for gasoline engines.

Its unique formula measures full synthetic molecules that have been refined. There is no need to be concerned about chemical power or cleanliness. Every incorporated part is very functional due to the protective characteristics. The uniform concentration causes a quick response to sustain the burning.

Its special blend contains useful additional components. A well-balanced portion means excellent support for cleanliness and fighting outcomes. Sludge, deposit, and buildups are combated with a premium mix fortification. Its expanded power is applicable to practically all current automobiles.

The oil fulfills the latest API SN PLUS Resource Conserving criteria, which means that the 0W-20 Extended Performance provides better fuel economy, lower emissions, increased turbocharger protection, and is compatible with ethanol fuels up to E85.

That sounds wonderful, but I’m sure you’d like the stats to speak for themselves, so here they are: Mobil 1 0W-20 Extended Performance protects the engine for up to 20,000 miles between oil changes.

ExxonMobil recommends Mobil 1 0W-20 for use in modern high-performance gasoline engines equipped with turbochargers and superchargers. Unless your Honda Accord was constructed in 2018 or later, it does not feature a turbocharger or a supercharger; however, this does not imply you should not use this engine oil in your Accord.

Turbochargers generate extremely high temperatures, necessitating the use of high-performance full synthetic engine oils that can “handle the heat.” This increased extreme heat stability isn’t required for the naturally aspirated engine found in most Accords, but it’s absolutely advised, and it’s one of the key reasons Mobil 1 may extend the oil drain interval up to 20,000 miles.

Mobil 1 0W-20 Extended Performance is API certified for gasoline engines, which is one of the requirements for Honda’s Accord. Aside from that, the oil satisfies or exceeds API SJ, API SL, API SM, API SN, API SN PLUS, API SN PLUS Resource Conserving, and older standards.

It is GM dexos1 Gen2 licensed, demonstrating its exceptional extreme-heat stability.

Mobil 1’s 0W-20 Extended Performance is, unsurprisingly, one of the best engine oils for the Honda Accord on the market.

Mobil 1 Extended Performance Motor Oil 0W-20 is ranked second on our list because it is somewhat more expensive than the Castrol EDGE listed above. Aside from that, it’s an excellent pick for a Honda Accord.


  • Superb chemical stability
  • Fully synthetic base-stocks
  • Service interval is safeguarded
  • Broad mechanical usability


  • No softening effects

3. Royal Purple SAE 0W-20 High Performance

It’s quite difficult to break into the oil industry, but Royal Purple is still going strong and has amassed a big following since customers couldn’t resist the amazing quality of their lubricants.

The Royal Purple SAE 0W-20 engine oil is a group V synthetic base stock engine oil — a true, high-quality fully synthetic oil. That is why it ranks third on our list of the best engine oil for Honda Accord.

In May 2020, GF-6, a fully new ILSAC performance standard, was introduced. To meet the GF-6 requirements, oil manufacturers had to improve their lubricant formulas to reduce engine wear (in order to pass the new timing chain wear test), provide better protection against LSPI (Low-Speed Pre-Ignition), which primarily affects small-displacement high-power turbocharged engines such as the L15B7 and K20C4 in the tenth-generation Honda Accord, and improve fuel economy.

Exceeding the most stringent industry standards is now the name of the game at Royal Purple, and it is the reason for their success in the incredibly competitive oil sector. Royal Purple High Performance engine oils have been GF-6 certified for well over a year.

Royal Purple High Performance engine oils have its own patented blend of additives known as Synerlec, which is one of the reasons Royal Purple synthetic oils outperform conventional oils. The Synerlec additive technique outperforms the requirements of the GM dexos1 Gen 2 as well as the preceding ILSAC GF-5.

The incorporated additives are activated by usable technology to commence relevant functions. There are numerous additives available to assist with the molecules. A clean surface provides a supportive environment for the components that are involved. There will be no more white sludge or lubricant deficiency.

Surface lubrication on a regular basis lowers metal contact, lowering frictional loss. To reduce fuel consumption, the chemistry regulates exhaust gas emissions. And it directly leads to increased resistance to wear and corrosion.

Royal Purple 0W-20 High Performance, like Mobil 1, is compatible with ethanol-containing fuels, thereby minimizing sludge development and lubrication starvation.

The 0W-20 High Performance oil is totally compatible with other synthetic and mineral lubricants that you may have previously used in your Honda Accord. It is strongly advised to wait until the manufacturer’s first planned oil change before switching to Royal Purple.

Royal Purple, like the other synthetic oils mentioned above, is API SN licensed and API certified for gasoline engines, as well as GM dexos1 Gen 2 approved.

Royal Purple 0W-20 High Performance is exceptional in every way. Because of the outstanding oxidation stability provided by group V synthetic base stocks, it allows for longer oil drain intervals, saving you time and money.

It may be overkill for a naturally aspirated 2.0L Honda Accord, but if your Accord has the new turbocharged VTEC beast under the hood, Royal Purple is the clear winner.


  • Chemical formula that has been stabilized
  • Anti-wear additive
  • LSPI resistance
  • Improved fuel economy


  • Slight initial improvement

4. Valvoline Advanced Full Synthetic SAE 0W-20

I’m sure you expected to see Valvoline on our list, and there’s a good reason for that: the 0W-20 Advanced Full Synthetic is a premium full synthetic oil that’s API SP and ILSAC GF-6A certified. And, like the Castrol EDGE, it’s quite affordable, and depending on the time of year, it might even be cheaper.

The anti-wear additives and detergents distinguish Valvoline Advanced Full Synthetic SAE 0W-20 from the other full synthetic oils on this list.

The formula concentrates especially on harmful factors. Wear, deposits, and heat are three of the key culprits. Its premium ingredients begin operating quickly against the agents. Your internal mechanism is cleaned, removing accumulated buildups.

The oil is API SP licensed, which means it protects against Low-Speed Pre-Ignition (LSPI), has improved timing chain wear protection (a big plus because timing chains are used in the 2.0L and 2.4L Honda engines), improved extreme temperature deposit protection for pistons and turbochargers, and better varnish and sludge control.

The 0W-20 Advanced Full Synthetic is now approved for the most recent ILSAC GF-6A, which was launched earlier this year, because it is API SP and API Resource Conserving licensed. Full synthetic engine oils had to pass the Industry Sequence X Chain Wear Test (Timing Chain test in short) in order to be approved for the GF-6A, and Valvoline nailed it. Valvoline’s 0W-20 Advanced Full Synthetic demonstrated 40% higher wear prevention than industry standards.

In terms of detergents, the 0W-20 Advanced Full Synthetic performed 25% better than industry standards during the GM Oxidation and Deposit engine test. Given this, it’s no surprise that the oil is GM dexos1 Gen2 licensed.

Valvoline’s 0W-20 Advanced Full Synthetic, like all full synthetic oils on our list, is API approved for gasoline engines, which is one of Honda’s primary needs for the Accord.

Because it is API SP certified, 0W-20 Advanced Full Synthetic is compatible with ethanol-containing fuels up to E85, as well as all other conventional and full synthetic engine oils.

The featured container holds 5 quarts, which is sufficient to fill the tank to a satisfactory level. In addition, the bottle has an easy-pull tab and a precise pour spout. Its sideways handle makes it easy to transport. Overall, the combination allows for simple smooth handling.

The proprietary SynPower technology is included in a fully synthetic formula. Durable chemicals initiate great resistance to abrasive stress. Excellent support for complicated systems is maintained through uniform concentration. It can also be used with other conventional or synthetic fluids.

Valvoline’s 0W-20 Advanced Full Synthetic is difficult to beat for the price. It has received all of the most recent API certifications, proving that it is one of the best full synthetic SAE 0W-20 grade engine oils on the market.

It’s a little much for an Accord, but with the price so low, there’s no excuse not to spoil your Japanese beauty.


  • Premium SynPower stability
  • Superior system security
  • Long lasting anti-wear additives

What to Look For When Buying Motor Oil for Honda Accord?

Oil API standards

API license is one of Honda’s primary criteria for engine oil used in the Accord. API, or the American Petroleum Institute, classifies engine oils and other chemicals for safer and easier use.

Honda expressly demands that the engine oil you choose have an API certification stamp that says “For Gasoline Engines.” Don’t worry, all of the engine oils on our top 5 list of best oil for Honda Accord carry the API certification seal.

Aside from that, API service categories are an excellent approach to assess engine oil quality and performance. As an example, consider the following:

API SP and API ILSAC GF-6A certifications are available for the premium Royal Purple 0W-20 High Performance. API SP is the most recent service category, which was launched in May 2020, and it is assigned to engine oils that provide protection against low-speed pre-ignition, timing chain protection, increased high-temperature deposit protection, and other benefits.

High Mileage Oils

Engines have a lot of moving parts that wear out over time due to friction. Because worn parts lose mass, the tolerances between them rise. Lifter noise is a classic example — a larger gap between the valve stem and the rocker arm causes that distinct and unpleasant tapping noise.

Moving parts aren’t the only ones that wear out with time; the continual heating and cooling cycles also take their toll on rubber seals and gaskets. Rubber seals and gaskets contract as a result of these temperature cycles, becoming harder and more brittle with time. Worn rubber seals and gaskets will no longer form a perfect seal and will eventually spill oil.

That’s where high mileage engine oil comes in. High mileage engine oil contains seal conditioners, which can swell up rubber seals and gaskets and, if you’re lucky, stop oil leaks. As a result, if your engine is showing signs of wear and getting it repaired isn’t an option, try high mileage oil.

No Additives Required

Oil additives are something we personally despise and highly advise against as technicians, and Honda feels the same way.

Honda clearly notes in the Accord owner’s manuals that engine oil additives are not required for their engines and may even have a detrimental impact on the engine’s performance and lifetime. And, like Honda, we believe that oil additives are largely marketing tricks.

They cause more harm than good, and if you buy API certified engine oil, it already contains all of the necessary additives. You’ll merely mess up the additive ratio and cause complications if you use additives.


How Much Oil Does the Honda Accord Require?

This may differ slightly between models, particularly generations. The four-cylinder engine typically requires 4.2 quarts of fuel, while the V6 engine requires 4.5 quarts.

The oil capacity of the Honda Accord has changed slightly in recent generations. The 1.5-liter engine uses 3.4 quarts of fuel, whereas the larger 2.0-liter engine uses up to 4.6 quarts. You should be alright purchasing a 5-quart bottle for a Honda Accord, as no model has a capacity greater than five quarts.

Is It Necessary to Use Synthetic Oil in Your Honda Accord?

Most Honda Accord owner’s manuals do not clearly state that you must use synthetic oil. However, Honda recommends using their own Genuine Honda oil, which is full synthetic, thus buying top quality API certified full synthetic motor oil is a smart idea.

Conclusion: Get The Right Oil For Your Honda Accord Now

Finally, you should get everything in the right oil. You must make the final decision from the list of the best oil for Honda Accord. The appropriate one offers to reduce your hassle in a variety of ways.

Bear in mind to use one with the API SN, SP, ILSAC GF-5, GF-6 specifications when selecting engine oil for your Honda Accord.

And the best oil has to be Castrol Edge Advanced Motor Oil. You don’t have to second-guess yourself when it comes to the fluid. It absolutely covers everything – quality, output, service, and price.
