What Type of Oil is Best for My Motorcycle Engine

Selecting the right oil for your motorcycle is essential to ensuring its optimal performance and longevity. In this comprehensive guide, we’ll explore the various types of motorcycle oils available and provide valuable insights to help you make the best choice for your bike. 

Whether you’re a seasoned rider or new to the world of motorcycles, understanding the importance of selecting the correct oil is crucial for maintaining your motorcycle’s engine health and performance. Let’s discover the factors to consider when choosing the best oil for your motorcycle engine.

Why Do We Need One

Engine oils play a crucial role in ensuring smooth and efficient engine operation. They allow metal parts to move freely, reducing friction and preventing excessive heat buildup, which could otherwise result in power loss. 

Additionally, they help maintain the integrity of the seals, preventing foreign particles from disrupting the combustion process. Without the right lubrication, your motorcycle’s engine might stop working altogether. 

Oil lubricates the engine’s internal components to control heat, minimizing friction and ensuring smooth, efficient movement to maximize mechanical output. It also carries heat away from these parts and cleans the engine’s internals in the process.

Why Must We Change the Engine Oil Regularly?

Due to modern engines’ precise engineering and tight tolerances, the high RPMs they operate at generate significant friction. Dirt and dust can also get in through seals, especially when riding on rough or muddy roads.

These small but important particles can accumulate inside the cylinder and on the heads, reducing engine efficiency. Additionally, the oil additives are designed to clean carbon buildup on engine parts. Regular oil changes help minimize sludge buildup by removing these particles with the old oil, keeping internal parts clean, and preparing for new oil.

Choose High-Quality Oil for The Bike

Here’s how you can choose the high-quality oil for your bike:

Understand Oil Types

Synthetic oils are crafted with more advanced lab modifications compared to mineral oils. They’re commonly preferred for newer motorcycle models, especially those with engines over 200cc. These oils offer excellent lubrication and protection, ideal for engines enduring heavier stress.

Check Your Bike Manual

Keep your bike in top shape with these easy checks! Make sure your wheels are secure, your saddle is tight, and your chain is clean and lubed. Spin your pedals, check your handlebars, and test your brakes. With these quick steps, your bike will be ready for any ride!

Riding Style and Conditions

When picking oil for your motorcycle engine, think about how you ride and where you ride. Your style, like cruising or racing, and the places you go, like hot deserts or cold mountains, affect how hard your engine works and what it needs from the oil. So, choose oil that fits how you ride and where you go to keep your engine running smoothly.

Consider Additives

Four-stroke engine oils contain more performance-enhancing additives, such as detergents, dispersants, and anti-wear agents. When selecting oils for your motorcycle, choose those with top-notch base oils and advanced additives for superior performance.

Viscosity Matters

Viscosity measures oil thickness. High-viscosity oils create a thick layer between engine parts, handling pressure well. However, they can also cause friction that robs power.

Types of Oil: Mineral and Synthetic

Mineral Oil

Mineral oils, as the name suggests, are naturally occurring forms of crude oil commonly used as standard lubricants. They offer great protection for new engines, particularly for motorcycles with smaller engine capacities (80cc – 125cc), which don’t generate high mechanical outputs. Their structure prevents molecules from bonding together under extreme conditions.

These factors contribute to the lower efficiency of this type of oil, necessitating more frequent replacement compared to synthetic oils. Although they are among the most budget-friendly options, they tend to have shorter lifespans, and high engine stress or aggressive riding techniques could accelerate component wear.

Synthetic Oil

For motorcycles above 200cc, synthetic oils are advisable due to their lower viscosity index. Unlike mineral oils, synthetic oils are entirely lab-created, with mineral oil used only as an additive. 

These oils work really well even when your engine is under a lot of stress because they’re great at lubricating and can handle high temperatures. Synthetic oils last longer and provide better engine protection, even for those who use a full tank of fuel daily or live in extreme temperature areas.

High-performance and trail motorcycles typically come with synthetic oils from the factory, although they can be costly to replace. However, it’s a worthwhile investment to keep your high-performance machine in top condition.

Difference Between 2-Stroke and 4-Stroke Engine Oils

Motorcycle and scooter engines come in two modes: four-stroke (4T) or two-stroke (2T). The difference is in how many times the piston moves up and down in each cycle.

2-Stroke Engine Oils

In 2-stroke engines, power is generated every two piston strokes. They’re more economical and lighter than four-stroke engines. However, they have several drawbacks, such as being less fuel-efficient, producing more noise and vibrations, and having a higher environmental impact. 

That’s why they’re often seen in smaller engines such as bicycles, mopeds, and go-karts. Two-stroke motorcycle engines require 2T engine oils, which can be made from castor, petroleum, semi-synthetic, or synthetic oils.

Nowadays, synthetic oils are commonly used in modern two-stroke engines because they offer superior protection and lower emissions. Additionally, advanced 2T oils include innovative additives that improve the performance of the base oils and introduce new features. 

These additives may consist of fuel stabilizers, detergents, anti-wear agents, biodegradable components, and other substances. Fubex offers a comprehensive range of high-performance 2T oils. 

The SPRING JASO FC 2T TC is a semi-synthetic motorcycle engine oil designed for two-stroke, air-cooled engines. This mineral-based lubricant provides optimal lubrication for your engine, ensuring maximum performance.

4-Stroke Engine Oils

In a four-stroke engine, power is generated every four piston strokes. Each stage—intake, compression, power, and exhaust—requires a separate piston movement. This design makes four-stroke engines more fuel-efficient and environmentally friendly than two-stroke engines. That’s why most modern motorcycle engines use this design.

For motorcycles equipped with a four-stroke engine, it’s essential to select high-quality four-stroke oil. Unlike two-stroke lubricants, four-stroke engine oils don’t combust with the fuel but instead circulate to lubricate engine components. 

Additionally, they aid in heat dissipation and the filtration of impurities. Four-stroke engine oils have more additives that boost performance, like detergents, dispersants, and anti-wear agents. Choose oils with high-quality base oils and these additives for your motorcycle.

What Does the Number on the Oil Can Mean

Have you ever felt overwhelmed at the auto parts store while trying to pick out a bottle of motor oil? You’re not alone! It can be tough to understand all those numbers and letters on the label. But don’t worry, we’re here to help.

Checking the Oil Grade

There are two rating systems for motor oil: the old and the new. Luckily, most oils on the market today use the newer system. In this system, “W” stands for winter, and “S” stands for summer, indicating how thick or thin the oil is at certain temperatures. 

A lower viscosity means the oil flows more easily when cold, while a higher number means it’s thicker and flows better when it’s warmer.

Requirements of the Lubrication System

To keep your motorcycle engine running smoothly, consider these lube oil system requirements:

  1. Match flow rate to total needs.
  2. Maintain proper pressure.
  3. Use reliable pumps and motors.
  4. Ensure effective filtration.
  5. Monitor with gauges and switches.
  6. Control temperature with heat exchangers.
  7. Adjust viscosity with immersion heaters.

What do the JASO MA and API Specifications Mean


JASO (Japanese Automotive Standards Organization) is a group of leading vehicle manufacturers in Japan. It was established to provide specifications specifically tailored to the needs of modern Japanese engines, as the existing API (American Petroleum Institute) standards were not adequate. JASO focuses on motorcycle engine requirements. 

The Japanese standard for special oil is designed for use in 4-stroke motorcycle engines with a single oil system for the engine, gearbox, and wet clutch. This fluid is non-friction modified, and these oils are specifically formulated for motorcycles equipped with a wet clutch. 

They provide the necessary friction performance to prevent the clutch from slipping and are thus non-friction modified. They are suitable for use in 4-stroke motorcycle engines where a single oil system is used for the engine, gearbox, and clutch. MA oils are ideal for all applications.


API standards are designed for automobile engines. The API code, consisting of double letters, categorizes oils for various uses. The first letter indicates the type of engine the oil is suitable for—’S’ for petrol engines (spark ignition engines) and ‘C’ for diesel engines (compression ignition engines). The second letter denotes the quality of the oil, with ratings ranging from ‘A’ (lowest quality) to ‘J’ (highest quality).

Motorcycle Engine Oil Specification

As you ride along, you might not think much about your motorcycle engine. But when it’s time for maintenance, choosing the right oil can be tricky. Different motorcycles need different types of engine oil. Here are some common specifications:

  1. Viscosity Grade: This tells you how thick or thin the oil is. You might see numbers like 10W-40 or 20W-50. The first number (like 10W) shows how the oil flows in cold temperatures, and the second number (like 40 or 50) shows how it flows when the engine is hot.
  2. API Service Classification: This shows how well the oil performs and if it’s right for your engine. For motorcycles, you might see letters like API SG, API SH, API SJ, API SL, API SM, API SN, etc.
  3. JASO Standards: These are specific to motorcycles and tell you if the oil works well with things like wet clutches. You might see labels like JASO MA, JASO MA1, JASO MA2, JASO MB, etc.
  4. ACEA Specification: This is less common for motorcycles but still important. It tells you if the oil meets certain performance levels. You might see labels like A3/B3, A3/B4, etc.

Bottom Line

In conclusion, selecting the right oil for your motorcycle isn’t just about keeping your engine running smoothly; it’s about ensuring your ride stays as exhilarating as the first time you hit the open road. From synthetic to mineral, understanding your bike’s needs and your riding style is key to maintaining optimal performance and longevity.
