Which oil should I use for my motorcycle ?

Choosing the right oil for your motorcycle is essential to preserve engine life, ensure proper lubrication, and prevent premature wear of parts. But with different standards, viscosities, and oil types, it can sometimes be difficult to know which one to pick. Here’s a simple and practical guide to help you choose the right oil for your bike.

What is motorcycle oil for ?

Motorcycle oil has several key functions:

• Lubricating the engine and reducing friction.
  
  
• Cooling certain mechanical parts.
  
  
• Cleansing by carrying away impurities.
  
  
• Protecting against corrosion.
  
  

Warning! Choosing the wrong motorcycle oil can lead to excessive consumption, loss of performance, and even engine failure. That’s why it’s important not to neglect oil maintenance for your bike.

What are the different types of motorcycle oil ?

There are several types of motorcycle oil, generally divided into three categories:

• Mineral oil, derived from petroleum, is often used for older bikes or during break-in, but it provides limited protection at high temperatures.
• Semi-synthetic oil offers a good balance between performance and price: it’s ideal for regular use in the city or on the road.
• Fully synthetic oil provides the best protection and stability, even at very high temperatures. It’s particularly suitable for modern, sporty, or high-displacement bikes, although it is more expensive.

Understanding viscosity grades

Oil containers always display a grade, such as 10W40 or 5W30. The first number before the “W” indicates cold-flow properties: the lower it is, the more fluid the oil remains at startup. The second number refers to the oil’s performance at high temperatures: the higher it is, the better it withstands heat. A 10W40 oil is highly versatile and suits most motorcycles, while a 5W30 is particularly suited to cold climates.

Which motorcycle oil should you choose ?

The choice of oil also depends on your motorcycle and how you use it. Scooters and small-displacement bikes work very well with 10W40 semi-synthetic oil. Touring and adventure bikes often require 10W40 or 10W50, either semi-synthetic or fully synthetic. Sport bikes, exposed to high RPMs and extreme heat, should be protected with fully synthetic oils like 5W40 or 10W50. As for older motorcycles, they are better suited to mineral oils designed for less modern engines. And to avoid staining your floor or garage when changing your oil, make sure to use a dedicated environmental motorcycle mat.

How often should you change your motorcycle oil ?

The oil change interval depends on the type of motorcycle, the oil used, and your riding style. On average, it’s recommended to change the oil every 5,000 to 10,000 kilometers, or at least once a year if you ride infrequently. Sport bikes or motorcycles used intensively (highway, spirited riding, extreme conditions) require more frequent oil changes, around every 5,000 km. Scooters and small-displacement bikes can sometimes go up to 6,000–8,000 km, while some modern large-displacement bikes can last up to 10,000 km with fully synthetic oil.

In any case, it’s essential to check the oil level and appearance regularly. If it becomes too dark, thick, or gives off an unusual odor, it’s best to change it immediately. And don’t forget to replace the oil filter with every oil change, to keep your engine clean and well-lubricated.

Practical tips for proper engine maintenance

Always refer to the owner’s manual, which is the best source of information for knowing which oil to use. Choose an oil with JASO MA or MA2 certification, specifically designed for motorcycles to protect the clutch. Be sure to perform regular oil changes, systematically replacing the oil filter to maintain engine cleanliness and prolong its life. Avoid car oils, which are not suitable for motorcycle engines and can cause mechanical issues.

Choosing the right motorcycle oil isn’t complicated if you follow the manufacturer’s recommendations and consider your bike type and usage. To sum it up: mineral oil for older motorcycles, semi-synthetic for daily use, and fully synthetic for performance and modern bikes. The right oil ensures a healthy engine, better performance, and peace of mind on the road.
