When I first started looking for the right oil for my motorcycle, I quickly realized how important choosing the right blend and viscosity is. Here’s what I learned about the Honda OEM Blend Motorcycle Oil 10W-40 and why it could be a great choice for your bike too.
Understanding the 10W-40 Viscosity
The “10W-40” rating tells me the oil’s thickness at different temperatures. The “10W” means it flows well in cold weather, helping my engine start smoothly in the mornings.

Compatibility and Usage Tips
Before I made my purchase, I checked my motorcycle’s manual to confirm that 10W-40 is the recommended viscosity. If your bike is older or has high mileage, this blend works well to maintain proper lubrication. Also, I made sure to change the oil regularly, as recommended by Honda, to get the best results.
