The Honda Grom is one of the coolest little bikes you can own. Like any vehicle, taking care of it is key to keeping it running smoothly. One of the most important parts of Grom maintenance? Choosing the right oil and changing it regularly. Why is oil so crucial? Well, think of oil as the lifeblood of your engine. It keeps all the moving parts lubricated, reduces wear and tear, and helps keep the engine cool. Without the right oil or proper maintenance, your Grom could face unnecessary damage, and nobody wants that!
In this article, I will explain everything about Honda Grom oil. You will learn which oil is best and how to change it. By the end, I hope your confusion will be clear and you’ll know exactly how to keep your Grom running like a champ for years to come. Let’s get started.
Recommended Oil Specifications
Honda Grom engines need the right oil to work properly. Using the wrong oil can harm the engine and lower its performance. Honda has specific requirements for the oil you should use.
First, the viscosity should be SAE 10W-30. This means the oil is thin enough for cold starts but thick enough to protect the engine at high temperatures.
Second, the oil must meet API SG or higher standards. These letters show the oil’s quality and its ability to protect the engine.
Third, it needs to meet the JASO T903 MA standard. This is important for bikes with wet clutches, like the Grom. It helps the clutch work smoothly without slipping.
Honda recommends using Pro Honda GN4 10W-30 oil. It is made for Honda motorcycles and meets all the requirements. If this oil is not available, you can use other brands that meet these same standards.
Always check the oil’s label before buying. Look for the viscosity, API rating, and JASO standard. This ensures you are using the right oil for your Grom.

What to Avoid
Avoid using oils that don’t meet the JASO MA standard. These oils may cause clutch slipping, which can affect the bike’s performance. Also, steer clear of automotive oils; they are not designed for motorcycles and can damage the engine.
Conventional vs. Synthetic Oil – What’s Best for Your Grom?
The Honda Grom can use both conventional and synthetic oil. Each type works, but they perform differently. Choosing the right one depends on how often you ride, where you ride, and how hard you push the engine.
Conventional oil is made from refined crude oil. It protects well in normal use. It is also less expensive. Many new riders use conventional oil for daily trips and short rides. Honda’s own GN4 oil is a mineral-based option. It meets all factory standards and works safely with the clutch system.
Synthetic oil is made using advanced processing. It flows better at cold start. It stays strong during high heat. It also lasts longer between changes. Riders who use their Grom in heavy traffic, long rides, or high temperatures benefit more from synthetic oil. Brands like Motul 7100 or AMSOIL Metric offer strong protection and cleaner engine operation.
For riders who ride once in a while or ride in normal weather, conventional oil is enough. For those who ride daily, use highways, or live in hot states, synthetic oil offers better protection. Both must meet 10W-30 grade and JASO MA standard. The choice is not about price. It is about how and where you ride.
Alternative Oil Viscosities
Honda recommends 10W-30 oil for the Grom. But some riders use other viscosities based on their needs. These choices depend on temperature, riding style, and personal preferences.
Using 10W-40 Oil
Some riders use 10W-40 instead of 10W-30. It is slightly thicker, which can help in hot climates. The extra thickness can provide better engine protection at high temperatures. But it may not flow as well in cold weather. Always check your owner’s manual before switching to a different viscosity.
Risks of Using the Wrong Viscosity
Using oil that is too thick or too thin can harm your engine. Thick oil may not reach small engine parts quickly. Thin oil may not provide enough protection under stress. Both situations can lead to engine wear and reduced performance.
Best Practice
Stick to the manufacturer’s recommendation for most conditions. If you live in an area with extreme heat or cold, talk to a mechanic or check your manual for advice. Always make sure the oil meets Honda’s API and JASO standards.
Oil viscosity affects engine performance. Use the right type to keep your Honda Grom running strong. It is a simple way to protect your engine and enjoy smooth rides.
Oil Change Intervals
Regular oil changes keep your Honda Grom engine in good shape. Old oil loses its ability to protect the engine. Fresh oil ensures smooth operation and reduces wear.
Recommended Intervals
For 2022 models, Honda suggests changing the oil every 4,000 miles. Older models need oil changes every 2,500 miles. These are general guidelines and work for normal riding conditions.
Frequent Changes
Many Grom owners prefer to change the oil more often. The Grom does not have a full-size oil filter. This means the oil gets dirty faster. Some riders change the oil every 500 to 1,000 miles. This keeps the engine clean and prevents problems.
Seasonal Changes
Change the oil at least twice a year. Once before the riding season starts and again after it ends. Even if you don’t reach the mileage limit, oil can break down over time. Fresh oil protects your engine during long periods of storage.
Signs You Need an Oil Change
Look for these signs:
- The oil looks dark or dirty.
- The engine feels rough or noisy.
- There is a drop in performance or fuel efficiency.
Stick to a regular oil change schedule. Fresh oil keeps your Grom running smoothly. It’s a simple way to extend your bike’s life and enjoy better rides.

Honda Grom Oil Capacity & Filter Info
The Honda Grom uses a small amount of oil. Most models from 2014 to 2025 need around 0.9 liters (900 ml) of oil during a standard change. If you clean or inspect the oil screen, you may need up to 1.0 liter. Always check the dipstick after filling. The oil level must stay between the lower and upper marks.
Unlike many large motorcycles, the Grom does not use a spin-on oil filter. Instead, it has a metal screen inside the engine. This screen catches dirt and small debris. You should clean this screen during every oil change. Some models also have a small spring and gasket near the screen. Place them back in the correct order.
If you want to install an aftermarket oil filter kit, choose one made for the Grom. These kits improve oil cleaning and may extend engine life. But they are not required. Honda designed the engine to work well with the built-in screen.
Always check the user manual or the side of the engine casing for exact oil capacity. Use a measuring container or clear markings on the bottle. Never guess the amount. Overfilling or underfilling oil can reduce engine performance or cause damage.
