Is It Okay to Use Used Motorcycle Engine Oil as Chain Lubricant?

Using used motorcycle engine oil as a substitute for chain lubricant might seem like a temporary solution, but it is generally not recommended. This article explores the reasons why and what you should know about using engine oil for your motorcycle's chain needs.

Understanding the Differences Between Engine Oil and Chain Lubricant

Engine oil and chain lubricant serve different purposes. Motorcycle engine oil is designed to lubricate the internal parts of the engine, while chain lubricants are specially formulated to provide the necessary lubrication for the external chain and sprocket. These lubricants are more sticky and designed to last longer, ensuring your chain remains properly lubricated for extended periods.

The Inefficiencies of Using Engine Oil for Your Motorcycle Chain

Engine oil has several limitations when compared to dedicated chain lubricants:

Reduced Durability: Engine oil does not stick as well to the chain and can easily fly off, leading to inadequate lubrication. A high-quality chain lubricant, on the other hand, lasts much longer, allowing you to ride up to 200 miles before needing to reapply. Chain and Sprocket Damage: Used engine oil, especially if not filtered, can contain debris and impurities that can damage your chain and sprocket over time. This leads to increased wear and potential safety hazards. Improper Lubrication: Engine oil tends to dry out faster and solidify at lower temperatures, leading to improper lubrication and increased friction. This can result in chain wear, jerky transmission, and reduced power output. Economic Considerations: Proper chain lubricant is generally more cost-effective in the long run compared to engine oil. Using chain lubricants designed for motorcycles ensures your chain remains in optimal condition, reducing the frequency of maintenance and extending your bike's lifespan.

Proper Maintenance and Alternatives for Motorcycle Chain Lubrication

Proper maintenance is crucial for the longevity of your motorcycle. Here are some guidelines for maintaining your bike's chain:

Chain Cover: If your bike has a chain cover, it is advisable to use chain lubricant instead of engine oil. A chain cover prevents oil from dripping onto the rim and other components, reducing the risk of damage. Frequency of Lube: For an open chain, clean and lubricate every 15 days or 500 kilometers. Tighter bikes, such as commuter motorcycles, can use engine oil due to the chain cover, but it is still recommended to use a dedicated chain lubricant. Emergency Situations: In case of emergency, you can use used engine oil as a temporary solution, but it is crucial to use only if no other options are available. Ensure the oil is clean and filtered to avoid debris and dirt from causing damage. Regular Inspection: For every 1,000 kilometers, check the chain's tightness to ensure the appropriate free play for optimal chain pick-up and mileage.

Natural and Artificial Lubricants: Comparisons and Recommendations

The best option for your motorcycle chain is a dedicated chain lubricant. However, if you have no other choice, using engine oil is better than nothing, although it is still not as effective:

Duration: Engine oil will not last as long as a proper chain lubricant and may only last a day or two. Grease, however, is the ideal choice in such situations. Viscosity and Performance: Engine oil is less viscous and less sticky compared to specialized chain lubricants like those from manufactures such as MOTUL. These lubricants are designed to penetrate the O and X rings, providing superior lubrication.

Conclusion and Final Thoughts

Using used motor engine oil as a substitute for chain lubricant is generally not recommended. While it might be a short-term solution in an emergency, it poses several risks including decreased durability, increased wear, and potential safety hazards. Follow the proper maintenance guidelines and use dedicated chain lubricant for the best performance and longevity of your motorcycle chain.
