Best Motorcycle Oils for 2024: Top 7 Picks and 3 Notable Mentions

Motorcycle oils matter. It’s true. And all brands are a little different. But the fact of the matter is all motorcycle manufacturers generally call for higher viscosity oils than those you get for your passenger car. Most of the time, motorcycles call for grades like 5W-40, 10W-40, 10W-50, and even 20W-50. Talk about throwing a wrench at you with all those numbers!

With so many options out there, it’s easy to get lost at your local auto-zone when all you really want to do is treat your bike right and give her the TLC she deserves.

But no worries, my dudes, because in this post, we’re going to talk about the best motorcycle oils out there for your bike. Plus, just to be certain you have plenty to choose from, I'll even throw in some notable mentions.

But before we get started, I want you to know upfront that I’m no mechanic (even if I may know a thing or two about motorcycle maintenance), so be sure to check your motorcycle manual to be sure you’re using the correct grade of oil for your bike. Whether you’re a weekend bike warrior, or you ride-out daily, this list was created to help every rider learn something new about oil for motorcycles. Let’s check them out:

When choosing the best motorcycle oil, there’s a few things that you have to look at. I mean, we’re talking about our prize possession here. We’re talking about our baby, our ride, and she’s gotta have the best. Plus, she’s gotta have the right motorcycle oil that has her purring like a kitten or roaring like a beast within. That means there’s some serious factors that come into play. Here’s what we’ve considered when we talk about oils for motorcycles:

• Viscosity: This is all about how thick or thin the oil is at different temperatures. Motorcycle engines run hotter and faster than your average car engine, so you need an oil that maintains its performance in those conditions. High viscosity means better protection at high temperatures. When you’re pushing your bike to the limit, this is what it needs.

• Base Oils: There are three main types—mineral, synthetic, and semi-synthetic. Fully synthetic oils are made to handle extreme conditions while semi-synthetics are more versatile. Choosing the right base oil affects everything from engine performance to longevity.

• Additives: Additives help reduce friction, prevent corrosion, and keep your engine clean. For motorcycle oils, the additives also need to be clutch-friendly since bikes often have wet clutches where the oil doubles up its job.

• Certifications: If your oil doesn’t meet certain standards, it’s not going in the tank. Certifications like API SN and JASO MA2 are a must.

• Price: While it's true that you often get what you pay for, we also consider value. Is the oil giving you a good bang for your buck, or is it overpriced motor juice?

• Brand Reputation: We looked at how long the brand has been around, what riders are saying, and whether they deliver on quality.

With these necessary criteria, we’re sure this list is packed with some of the best motorcycle oils around to keep your ride running no matter where the road takes you.

Here’s the straight-up truth: Sure, you can mix different brands of motorcycle oil, but why would you? Mixing oils is literally like mixing your whiskey. It’s just going to muddy-up your flavor. Stick to one brand, because mixing motorcycle oils can lead to inconsistencies in performance and may affect the protective properties.

Synthetic oil offers better performance, longer drain intervals and better engine protection. It’s made from chemically modified base oils.

Mineral oils are made from crude oil and offer basic protection. Mineral-based oils are lower priced oils that flow through the engine slower, which results in increased fuel consumption. This affects engine performance.

Overall, so long as your bike isn’t the Honda that needs the Honda GN4 10W-40 Motorcycle Oil, then synthetic oil for motorcycles is the way to go.

You better believe it is. Your bike has needs. The Honda needs that Honda-specific oil that’s specifically mineral-based, my friend. Don’t skimp on that good-good when it comes to the things you care about like your motorcycle. Keep your engine happy with motorcycle-specific oil.

Let’s cut to the chase: choosing the right motorcycle oil is mission-critical. You want your bike to perform like a beast and last forever? Then you need the right oil.
