What is the Oil Capacity of the 2021 Honda HR-V?
published on November 6th, 2022 by Searchforparts.com
A 2021 Honda HR-V with a 1.8L engine (4 cylinders) needs 0W-20 oil. It has an oil capacity of 3.7 quarts (without a filter) and 3.9 quarts (with a filter).
You may have heard about synthetic, conventional, or synthetic blend oil as a car owner. These oils are great, and each offers its benefits to your car. Synthetics are the most popular of the three and have been recommended for most modern vehicles. They offer a higher viscosity and are less likely to break down and release harmful environmental emissions.
In addition, conventional oil is a great lubricant but contains impurities and may pose a danger to the emission crisis. The synthetic blend is simply a combination of the two oils. Honda manufacturers recommend using genuine synthetic or commercial engine oil of suitable viscosity (0W-20) with the appropriate API Certification Seal. For heightened performance, periodic oil changes must ensure the engine components stay well-lubricated.
Protect your Honda! Get synthetic that does not break down under extreme heat and protects your engine! Lab tested for performance and it is 100% synthetic, not a blend. Get the filter to go along with the oil below and not worry about constant oil changes. This is great for ride share contractors, road warriors who drive tons of miles, or anyone who wants to avoid the hassle of oil changes at the dealership. The dealer won’t put in the oil of your choice? Buy the oil and take to a local mechanic! Made in USA oil!

When should I do the first oil change for a 2021 Honda HR-V?
When you purchase a new 2021 Honda Hr-v, an oil change is essential and should be done regularly to preserve the engine’s longevity. We recommend you make this change based on the owner’s manual or if you have a top synthetic, it may exceed the expected interval
It is good practice to check your oil level each time you refuel. This way, you can detect when its level drops or begins to change color.
Note: You may need to change your engine oil before the recommended change intervals if;
- The check light turns on;
- You notice exhaust smoke from your HR-V
- You hear weird noises coming from your engine.
How often should I change my oil with full synthetic?
Synthetic oil is known for its high viscosity index and strong oxidation resistance. Its additives give your engine an edge in protection from contaminants, rust, and other forms of engine wear. All things equal, your full synthetic oil is built to last longer in your engine than conventional oil. It means that it takes longer miles for an oil change with full synthetic oil than with conventional oil.
Honda manufacturers recommend an oil change within every 3,000 – 5,000 miles for conventional oil. Synthetic oil lasts longer miles with oil change intervals every 7500 – 10,000 miles or even up to 15,000 miles or 1 year, whichever comes first.
Should I change my oil based on time or mileage?
Oil change based on time or miles will depend on various factors. For instance, If you have driven more miles within a short period, you may need to change it based on miles.
Likewise, an oil change should be based on time if you don’t drive long distances over a year. Usually twice a year, every six months. Many manufacturers recommend an oil change 2-3 times a year. It is because the quality of engine oil degrades over time whether or not you drive often.
Can I still drive my car with 5% engine oil life left?
The oil life percentage reminds you that your engine is due for an oil change. It doesn’t necessarily mean your engine level is low; however, it could indicate a low oil quality due to contamination.
For instance, having a 5% engine oil life left isn’t a critical issue that affects drivability. Instead, it indicates that your engine’s oil quality has dropped and needs to be changed. You may still drive the vehicle for another 1,000 miles before changing the oil. However, we recommend that you change the engine oil within 1000 miles.
Does synthetic oil improve gas mileage?
To an extent, synthetic oil helps improve gas mileage. For one, it contains a lower oil viscosity level, which benefits fuel economy. The lower the oil viscosity level, the easier it flows to other engine components. So, your 0W-20 motor oil, with its reduced resistance to flow, would require less energy (fuel). Also, in colder climates, the improved flow of synthetic oil would result in a better cold start while conserving energy.
When you compare synthetic oil to other engine oils, the difference in energy conservation is not so visible. So, synthetic oil can improve your gas mileage, but not to a draggable extent.
How to inspect the Oil level in a Honda HR-V?
Regular oil checks are a healthy way of preserving the functionality of your engine. If you aren’t familiar with this process, you can start by reading the owner’s manuals. You can familiarise yourself with the equipment and system (electronic oil or manual system).
You can follow these manual steps:
- Park your Honda on level ground. Turn off the engine and wait for it to cool. Do not open the hood immediately to prevent heat burns from the hot engine and the hood.
- After the engine cools, pop the car hood and check for the dipstick. You can refer to the owner’s manual.
- Pull out the dipstick and clean it with a cloth.
- Re-insert the dipstick into the engine and pull it out again.
- Inspect the dipstick for oil streaks. The oil level is okay if the oil streaks fall between two marks or within a cross-hatched area. If not, add more oil – be careful not to overfill.
Typically, oil checks should be made at least once a month. However, checking your oil levels each time you refuel is good practice.
Our recommendation
Quality oil remains the backbone for high performance in engines with long-lasting duration. If you use a conventional oil change, we recommend 3,500 and 5,000 miles \ one-year oil change intervals. In contrast, you should have an oil change every 7,500 to 10,000 miles for synthetic oil. Notwithstanding these rules, regular oil checks should be made at least once a month to prevent oil levels from reaching dangerously low. If you buy Amsoil signature series oil you can change your oil only 1 time per year or up to 15,000 miles. This is great because it saves time and money, especially for ride-share drivers.
