Types of Bike Engine Oil

  1. Mineral Oil: It is ideal for new and old-school motorcycles, facilitates the smooth mating of engine parts during the initial use, and is cost-effective.
  2. Synthetic Engine Oil: Ideal for High CC Bikes. It offers lower viscosity for reduced friction, enhancing engine longevity and fuel efficiency, but it comes at a higher price.
  3. Semi-Synthetic Engine Oil: Ideal for Mid-Segment Bikes. A blend of crude and synthetic elements provides excellent cooling and slower degradation but is not suited for high-performance engines due to potential premature wear.


Engine Oil Grades

Engine oil grades, defined by the SAE (Society of Automotive Engineers), indicate oil performance across varying temperatures, focusing on viscosity—its resistance to flow. For example, in “10W-30”.

  • “W” signifies winter suitability.
  • “10” indicates low-temperature viscosity, with lower numbers being better for cold starts.
  • “30” denotes high-temperature viscosity, where higher numbers favour high-temperature operation.

Choosing the Right Engine Oil based on your motorcycle type and usage


– Viscosity

Viscosity, a measure of an oil’s thickness and flow capability at different temperatures, ensures your engine runs smoothly under various conditions.

– Importance of Choosing the Right Viscosity for Climate and Riding Conditions

The correct viscosity is essential for optimal engine performance and protection. High-viscosity oils (such as 10W-40 and 20W-50) are thicker and slower to flow. They are better suited for hot weather, providing a more substantial film barrier against wear.

On the other hand, low-viscosity oils (such as 5W-30 and 10W-30) flow more easily at low temperatures, ensuring your engine receives adequate lubrication during cold starts, which is crucial in cooler climates.


# Engine Oils for Different Riding Styles and Conditions

  • Best Engine Oils for City Commuting

For the stop-and-go nature of city commuting, oils with excellent thermal stability and low viscosity are ideal. They ensure smooth engine operation and fuel efficiency in varying temperatures. Look for oils labelled “Energy Conserving” in the 10W-30 or 10W-40 grades.

  • Top Picks for Long-Distance Touring

Long-distance riders should opt for synthetic oils that offer superior protection against wear and high temperatures over extended periods. Viscosity grades like 10W-40 or 15W-50, known for their endurance and high-temperature stability, are recommended.

  • Recommended Oils for Off-Road Adventures

Off-road motorcycles benefit from oils that can handle the dust, debris, and mud typical of such environments. Semi-synthetic or synthetic 10W-40 or 10W-50 oils, which offer excellent protection and cleanliness under harsh conditions, are advisable.

  • High-Performance Oils for Racing and Sport Motorcycles

Racing and high-performance motorcycles require oils that can withstand extreme stress and high temperatures without breaking down. Synthetic 10W-40 or 20W-50 oils, designed for high RPMs and maximum power output, are the best choice for these demanding conditions.


# Changing Your Motorcycle’s Engine Oil


1. Warm Up Your Engine: Start your bike and let it idle for 3-4 minutes before draining the oil to ensure it flows out smoothly.

2. Change Interval by Engine Size –

  • 100-200cc: Change the engine oil every 1,000-1,500 km.
  • 200-500cc: Change the engine oil every 1,500-4,000 km.

Note: These are general guidelines. Refer to your motorcycle’s manual for specific oil change intervals and specifications, including the correct grade and service rating.

3. Consider Riding Style –

  • Frequent full-throttle riding: Change oil sooner than recommended.
  • Daily riding: Stick to timely oil changes for optimal performance.
  • Infrequent use: Check and possibly change oil before riding again.
  • Long-distance rides: Change oil after extensive journeys to address the extra engine stress.

4. Use Recommended Engine Oil: Follow the API and JASO standards mentioned in your bike’s manual.

5. Replace Oil Filter: To ensure the best engine performance, change the oil filter with every oil change.

6. Drain Plug Maintenance: Occasionally replace the drain plug to avoid oil leaks.
