The best motorcycle oil

Today, we’ll be recommending some of the most high performing motorcycle oils for your motorcycle. 

With ample experience working on motorcycles, we took into account the specific compounds and manufacturing methods used to produce these oils, but the ultimate deciding factor for whether or not we approve of them was first hand testing. 

Having put them through rigorous tests, we are confident that the following are the best motorcycle oils on the market, owing to their unique formulation and effectiveness in improving your bike’s performance.

We found Motul delivers the best overall package with their 300V synthetic engine oil, an oil tailor made for high revving, high performing engines, perfect for sportbikes, streetfighters and Harley Davidson too. 

Motul 300V Synthetic Engine Oil

#1 Best Overall

Motul claims this engine oil is made specifically for the highest revving engines in race bikes. Our testing proved that accurate, as the 300V outperformed all of its peers in extracting power, minimizing shear, and making the motorcycle ride smoother. 

Motul claims this engine oil is made specifically for the highest revving engines in race bikes. Our testing proved that accurate, as the 300V outperformed all of its peers in extracting power, minimizing shear, and making the motorcycle ride smoother. 

This 10W-40 fully synthetic engine oil uses Ester core technology to maximize your engine’s power output. Using it for our Yamaha YZF R6, there were no magical +10 HP gains, but this oil made a noticeable difference in throttle response and engine character. One of our testers described the bike as being ‘more peppy’ thanks to the improved acceleration. 

With additives that reduce abrasion and clean your engine as you use it, a smoother ride is one of the main benefits of this oil. Motuls oil is designed to minimize the shearing effect of metal on metal. This oil even made startups on the R6 a lot smoother. 

Riding in town was a bit more comfortable than before, with the engine managing heat more effectively too. But really, the minimized shearing is ideal for engine longevity and long term performance. 

A big concern for many motorcyclists is whether the engine oil is suitable for their particular engine configuration. The 300V is best suited to 4-stroke engines, such as sportbikes and ADVs. It doesn’t matter whether you’re running a catalytic converter or not. Both wet and dry clutch bikes are supported, and the motorcycle passes the JASO T904 wet clutch test. 

Pros
  • Best for sportbikes, streetfighters
  • Better abrasion resistance
  • Improved engine lifespan
  • 0% shear loss on Bosch test
  • Smoother ride
  • Better engine cooling
  • Wet/dry clutch compatible 
Cons
  • More suited to use in summer
  • Can be a bit expensive

Mobil 1 Racing Engine Oil

#1 Budget Choice

Nothings beats a budget friendly, high quality motorcycle engine oil. Mobil 1’s Racing Engine oil delivers top shelf oil benefits like improved engine response, cleaner running, and smoother riding for bargain bin prices.

Few things beat a budget friendly, high quality product. Mobil 1’s Racing Engine oil delivers top shelf oil benefits like improved engine response, cleaner running, and smoother riding for bargain bin prices.  

In a nutshell, the Mobil 1 does what other great oils do, just at a cheaper price. That makes this oil ideal for bikes that see tens of thousands of miles every year and need cheaper engine oil. In our experience, the Mobil 1 upgraded our engine’s throttle response and made riding noticeably smoother, especially for long trips. 

While it is intended for street use on 4 stroke motorcycles, we had an equally good experience using the Mobil 1 off road in our ADV. It reduced shearing and abrasion, protecting the engine for many miles. Starting up the bike with this oil for the first time, the difference was apparent. The Ignition was quicker and even sounded better. 

More so than the engine, this oil works to protect your gearbox and clutch mechanisms. Shifting up and down was a lot easier and more confidence inspiring. This oil even eliminated a concerning sound in our bike’s transmission when shifting from 2nd to 3rd gear. That alone is enough to earn the Mobil 1 a place on this list, but it’s a terrific option regardless. 

Pros
  • Protects engine from wear and tear
  • Also lubricates clutch and transmission well
  • Better throttle response
  • Smoother ride quality
  • Budget friendly
  • Great for bikes that are used a lot
  • Eliminates a lot of engine and transmission noise
  • Makes shifting smoother
Cons
  • Not the best choice for air cooled engines

Motorex Power Synt 4T Engine Oil

#1 Premium Choice

Another engine oil developed for motorsport, the Motorex Power Synt 4T is also excellent for everyday use. We were impressed by the improved engine smoothness this oil offers and the advanced abrasion resistance, helping reduce wear and tear. 

Fully synthetic oils like this one are great for boosting engine performance. It allowed our test bike to tap into previously dormant power while keeping the engine safe from general wear and tear. 

Moreover, it protects the engine components during ignition, when they are usually most vulnerable to shearing. With the Motorex, ignition and idle are a lot smoother and safer. 

Besides protecting the engine from damage, Motorex’s oil cleans it too. The various engine parts are coated in lubricating oil to prevent excessive abrasion, but the oil also helps filter out any contaminants that could cause deterioration. This is thanks to Motorex’s specially designed additives that work to clean your engine. 

Efficiency on our test bike also improved. We got slightly better mileage using this oil over other options, though nothing to write home about. But the difference in ride quality was more noticeable: smoother engine response, more pleasurable riding, and less heat coming off the bike around our main takeaways. 

Finally, the Motorex gets extra points for being usable almost year round. This oil is suitable for both warmer and cooler climes, both in summer and winter. A small detail, but one that makes a significant impact long term. 

Pros
  • Reduces wear and tear of engine components
  • Cleans engine of impurities 
  • Makes ride smoother
  • Improved fuel mileage 
  • Slight improvement in engine response
Cons
  • Fully synthetic oils are prone to leaking
