More than a million motorcycles are sold in the US each year. And with motorcycles come maintenance requirements. If you want to keep your bike in tip-top shape, you’re going to need a good oil. Oil will keep the engine lubricated, the pipes clean, and the bike performing at peak efficiency. But not all oils were created equal. Don’t risk your bike’s health or performance on an inferior product.

When it comes to motorbike oils, all oils, regardless of price, manufacturer, or quality, can be categorized into one of the following:

  • Fully Synthetic – Fully synthetic oils are the most common variety. Durable and long-lasting, they tend to stand up to disintegration far better than their natural counterparts. Price ranges can fluctuate, depending on the brand.
  • Semi-Synthetic – Semi-synthetic motorcycle oils feature a blend of refined crude oil and synthetics. Fans of this type cite its superior performance to all-natural products, not to mention its greater affordability compared to fully synthetic types.
  • Natural – Natural or conventional motorcycle oils are made of refined crude oils with the addition of additives. The most affordable of all the varieties, it tends to be favored by those with a penchant for lubricant-demanding classic motorcycles.

Of course, evaluating the performance of an oil involves more than simply looking at its type. If you want to do the best by your bike, you might want to consider investing one from our round-up of the ten best motorcycle oils of 2020.
