Taking care of your Aprilia Dorsoduro 900 ensures you get the most out of its performance. Oil changes aren’t just maintenance; they’re the heartbeat of your bike’s health. With the right oil type, proper oil capacity, and a straightforward oil change routine, your motorcycle will stay in great shape for the long haul.
Synthetic vs. Conventional Oil: What’s the Difference?
When it comes to motor oil, you’ve got two main contenders: synthetic and conventional. Each has its own story.
Synthetic Oil
Synthetic oil is like a tailored suit for your engine. It’s built molecule by molecule to enhance engine performance. It’s cleaner, more uniform, and free of impurities like sulfur or metal. This precision gives your engine better wear protection and keeps it running smoothly in both hot and cold conditions. Think fewer trips to the shop and less stress on your engine. Bonus? Longer intervals between oil changes.
Conventional Oil
Conventional oil, on the other hand, is the old-school option. It’s refined from crude oil, which means it carries natural impurities, even after processing. Over time, these impurities can build up, reducing performance and making your engine work harder than it should. While it gets the job done for basic needs, it doesn’t hold a candle to synthetic when it comes to wear protection and efficiency. If you push your bike hard, you’ll notice the difference.
