Choosing the Right Type of Engine Oil for Honda Accord
The Honda Accord is one of the most reliable vehicles ever built! So, it is great you are taking care of it by changing the oil regularly (I recommend every 5000 miles).
The best type of oil to put in your engine depends on a number of factors. I spent a fair amount of time researching these factors, and I am writing this article, so you don’t have to!
At the end of the day, there are mainly 2 things you need to think about when choosing the best oil for your vehicle: mileage and climate. Even though there are a host of other things to consider, such as how you drive, what your daily drive is like, or whether your vehicle has any known problems. I’m going to assume you are a ‘typical’ driver, you live in a climate with cold winters and fairly warm summers, and the car doesn’t have major issues.
Concerning mileage, an important factor is also the age of the vehicle in terms of how many miles are on the car. “High Mileage” is considered 75,000 miles or more, which to a Honda owner, actually isn’t that much! It is pretty common to see Honda Accords with well over 250,000 miles, still going strong! The reason that high mileage motor oil can be important is because of the specific formulation of additives. The additives for high-mileage vehicles are designed to restore the shape and pliability of engine seals bringing new life to those that may have hardened over time. High-mileage oils also tend to be toward the higher range of viscosities within each specification to account for increased tolerances that may exist in vehicles that are older and have experienced more wear.
Consequences of Using the Wrong Engine Oil in a Honda Accord
Using the wrong type of oil in your Honda Accord can lead to various engine problems, affecting performance and potentially causing long-term damage. The choice of oil is crucial as it directly influences the engine’s lubrication, cooling, and overall efficiency.
One common issue that can arise is the clogging of the Variable Valve Timing and Lift Electronic Control (VTEC) solenoid. The VTEC system is responsible for optimizing valve timing and lift for improved engine performance. Using an incorrect oil viscosity or one that doesn’t meet Honda’s specifications can result in sludge buildup, obstructing the VTEC solenoid’s proper functioning. This may lead to reduced engine efficiency, power loss, and even engine misfires.
Another critical component affected by the wrong oil is the Positive Crankcase Ventilation (PCV) valve. The PCV system is designed to control and recycle the gases produced during combustion. If the wrong oil is used, it can lead to increased deposits and sludge formation within the engine. Over time, these deposits can accumulate in the PCV valve, causing it to clog. A clogged PCV valve disrupts the proper ventilation of the crankcase, leading to increased pressure inside the engine. This pressure buildup can result in oil leaks, reduced fuel efficiency, and potential damage to engine seals and gaskets.
Additionally, using an improper oil may impact the engine’s overall lubrication effectiveness. The wrong viscosity or oil composition can fail to provide sufficient lubrication to critical engine components, leading to increased friction and wear. This can accelerate engine aging, reduce fuel efficiency, and potentially result in costly repairs.
Choosing the right oil for your Honda Accord ensures optimal engine performance, longevity, and fuel efficiency while minimizing the risk of costly repairs and maintenance. Regular oil changes with the correct oil type and viscosity are fundamental to the overall health and longevity of your vehicle’s engine.
How to Change the Oil in a Honda Accord?
Changing the oil in an Accord is very straightforward and takes about 20-30 minutes; most of the time is spent waiting for the used oil to drain out of the car! Please visit this post for details on changing the oil in an Accord. All you’ll need is a 17mm socket, funnel, 4.4 qts of oil, a drain pan, and an oil filter.
What Viscosity is Right for Me?
When you see the numbers on the bottle like “5W-20”, very simply, the first number corresponds to the viscosity when the oil is cold (think “W” for “winter”). The number before the “W” refers to the viscosity rating at 0°C. A lower number means there is less thickening of the oil at lower temperatures. The number after the dash (-) refers to the viscosity of the oil measured at 100°C and is an indication of the oil’s rate of thinning at higher temperatures. Visit this post for a more detailed explanation of the SAE numbers.
Why should I use Synthetic Oil?
- Synthetic oil allows your vehicle to get better gas mileage. Since synthetic oil can be manufactured down to higher viscosity ratings than conventional oils, the oil flows more freely, allowing the engine to not have to work as hard.
- Synthetic oils can also go longer between oil changes. This not only saves YOU money, but also reduces waste.
- Synthetic oils increase engine longevity. If everything else is the same, an engine will last longer if synthetic oil is used.
What Oil is the Best Oil?
Before 2011, Honda recommended the use of 5W-20 oil in their Accords. From 2011 and onward, the recommendation changed from 5W-20 to 0W-20. The reasons for this comes down to tighter tolerances in engine manufacturing processes and fuel economy. In fact, if a vehicle will be used for towing, 5W-30 oil is recommended in order to increase the engine life.
For these reasons, the following oil types are recommended based on the year of the vehicle.
For a Honda Accord made in 2011 or newer, use this:
Mobil 1 Extended Performance Full-Synthetic 0W-20
For a Honda Accord made in 2010 or earlier, use this:
Mobil 1 Extended Performance High-Mileage Full Synthetic 5W-20
Honda Accord Oil – Viscosity, Pour Point, Density, and Flash Point
In this section we conduct a comprehensive exploration of crucial engine oil properties that play a pivotal role in maintaining the peak performance of your Honda Accord, namely: Viscosity, Pour Point, Density, and Flash Point. Understanding these characteristics is essential for every car enthusiast and Honda Accord owner, as they directly impact the engine’s lubrication efficiency, longevity, and overall smooth operation.
1. Viscosity: Viscosity is a measure of a fluid’s resistance to flow. In the context of engine oil, it is one of the most critical factors influencing its performance. There are different viscosity specifications, notably Viscosity @ 100°C, Viscosity @ 40°C, and Viscosity Index. Viscosity @ 100°C indicates the oil’s thickness at operating temperature, while Viscosity @ 40°C measures its flow characteristics at a lower temperature. The Viscosity Index reflects the oil’s ability to maintain consistent viscosity across a range of temperatures. Proper viscosity ensures that the oil effectively coats engine components, reducing friction and wear for smooth operation.
2. HT/HS Viscosity: High-Temperature/High-Shear (HT/HS) viscosity is a crucial measure at elevated temperatures and shear rates. It indicates the oil’s ability to maintain a stable viscosity under high-temperature and high-shear conditions. This is particularly important in modern engines with tight tolerances, as it ensures proper lubrication in demanding operating conditions, preventing metal-to-metal contact and reducing wear.
3. Pour Point: The Pour Point of an oil refers to the lowest temperature at which it can flow. This property is crucial for cold starts, as it determines the oil’s ability to circulate in the engine when temperatures are low. Choosing an oil with an appropriate pour point ensures proper lubrication even in chilly conditions, reducing engine wear during startup.
4. Flash Point PMCC: The Flash Point, measured by the Pensky-Martens Closed Cup (PMCC) method, is the temperature at which oil vapors can ignite when exposed to an open flame. While not directly impacting engine performance, a higher flash point indicates better resistance to thermal breakdown. This is crucial in engines that operate at high temperatures, as it ensures the oil remains stable and continues to provide effective lubrication.
5. Density: Density is the mass of oil per unit volume. While not as commonly discussed as other properties, it plays a role in fuel efficiency. Optimal density ensures that the oil doesn’t contribute unnecessary weight to the engine, helping maintain fuel economy.

ASTM D2270 provides a standardized approach to calculate VI based on kinematic viscosity measurements at 40°C and 100°C. This method enables precise assessments of the oil’s ability to maintain consistent viscosity in various operating conditions, crucial for preserving engine efficiency and reducing wear.
3. ASTM D4683 – Standard Test Method for Measuring Viscosity of New and Used Engine Oils at Low Temperature (Low-Temperature Cranking Viscosity Using a tapered, Rotating, Low-Temperature Viscometer)
Cold weather performance is a significant concern for engine oils, particularly during startups. ASTM D4683 addresses this by measuring the Low-Temperature Cranking Viscosity, providing valuable insights into an oil’s flow characteristics at low temperatures. This standard is vital for ensuring optimal lubrication, minimizing engine wear, and preventing potential issues during cold starts.
4. ASTM D97 – Standard Test Method for Pour Point of Petroleum Products
The Pour Point, as determined by ASTM D97, indicates the lowest temperature at which an oil can flow. This test is critical for understanding the oil’s behavior in cold climates, ensuring it remains fluid enough to circulate and lubricate engine components during chilly starts. Choosing an oil with an appropriate pour point is essential for maintaining engine health and preventing wear in cold weather conditions.
5. ASTM D93 – Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester
Flash Point, measured by ASTM D93, is the temperature at which oil vapors can ignite when exposed to an open flame. While not directly influencing engine performance, a higher flash point signifies greater resistance to thermal breakdown. This is particularly important in engines operating at high temperatures, ensuring the oil remains stable and effective in extreme conditions.
6. ASTM D4052 – Standard Test Method for Density, Relative Density, and API Gravity of Liquids by Digital Density Meter
Density, relative density, and API gravity are critical parameters in assessing the overall quality of engine oils. ASTM D4052 standardizes the measurement of these properties using a digital density meter, providing accurate data for evaluating the oil’s composition and compatibility with engine systems. Maintaining optimal density is key to preserving fuel efficiency and engine performance.
In conclusion, adherence to ASTM standards is paramount for selecting, testing, and ensuring the quality of engine oils.
