Buying Guide: What Factors To Consider Before Buying The Motorcycle Oils

Let’s look into the factors that matter while selecting the Motorcycle Oil for your bike.

The Viscosity Of The Oil

You might have seen W, followed by some random numbers on the packaging of the engine oils. These numbers are not random, instead, define the viscosity of the oil at different temperatures. Generally, the numbers before ‘W’ would define “Cold” Viscosity and the after ones are meant for “Hot” viscosity. So, if you are planning a trip to a colder place, then the number before W should be low and so on. Similarly, there are other abbreviations such as JASO MA2, SAE, that you should be aware of before picking up the right engine oil.

The Gap Between The Two Services

Generally, the manufacturers would recommend the service frequency for the vehicles. During the servicing, engine oil plays a leading part in enhancing the life of the engine and revving up your bike again. However, if you have missed a few services, then prefer the engine oil meant for the bikes that have covered higher miles without getting serviced as and when required.

Fully Synthetic Or Semi-Synthetic

For the high-performance bikes, fully synthetic oil is most preferable. These synthetic oils are loaded with anti-wear additives and viscosity improvers. Although the synthetic blends or semi-synthetic oil would have the same specifications, your bike performance might not be optimum, and neither would be the engine protection.

Compliance Standards

All major brands of engine oils will mention the standards with which they are compliant. Look for the abbreviations such as API, JASO, or SAE on the bottles as these symbols indicate the quality of the oils.


Best Motorcycle Oils reduce the friction of the engine parts, thereby increasing the performance and longevity. Even during the servicing of the bikes, oiling is considered one of the most critical parts to ensure the smooth functioning of the bikes.

For our readers, we suggest that they should consider different factors we discussed before buying a suitable engine oil for their bikes. We hope our detailed buying guide and product reviews would help you in making a better purchase decision.
