Motul 300V vs 8100: What's the Difference?

This is one of the most frequently asked question of any car owner. When it comes to picking the right Motul engine oil, which is better suited for my car: the 300V or 8100?

Both are 100 percent synthetic engine oils, synthesized and produced free of any mineral or crude oils. This ensures that Motul can control the quality of every drop of oil in the bottle, as opposed to having to refine the quality of mineral base oils.

Now, as Motul’s top-of-the-line, full synthetic racing engine oil, 300V is their most well-known product. But while 300V is cutting-edge stuff (and you can certainly use it in every application) it doesn’t mean you should do so. When it comes to protecting the engine, sometimes it’s not really the case of which is “best,” but rather, which is most suitable.

The most important thing to know is that 300V is truly a racing oil. Mechanics at the Dakar Rally or Le Mans endurance race pour it into the competition vehicles they service, and it’s the exact same stuff you can buy off the shelf at your Motul dealer or service provider.

Racing oils provide the same things that ‘street’ (or regular) oils do: Improve power, protect the engine, and improve the reliability and longevity of components. 300V is a very specific product, and there are even different formulations for different racing applications, from sprint races to endurance rallies.

300V does its job well, but unlike 8100, it’s designed, as is typical of a racing lubricant, to have a more frequent replacement interval than a street oil like 8100. 8100, as a high-quality lubricant, can be changed at your car’s stated service intervals while 300V would require replacing far sooner for the optimum performance.

So, besides those with actual racing cars, who should use 300V? Avid motorsport enthusiasts whose vehicle are in a high state of tune or which are used regularly at track days or sporting events such as time attacks, gymkhana, or drag races. And that’s not to say 8100 can’t do it either, those who attend occasional track days but do a majority of driving on normal roads will find 8100 up to the task.


  1. Motul 8100 - Group IV oil
    Motul 300V - Group V oil

    Both are better than your regular synthetic blend which is typically just Group III (not 100% synthetic or semi synthetic). Group IV and beyond matters since it is so hot here in the Philippines especially in heavy traffic conditions. The main reason why most people suggest using 5w40 on an engine that takes 5w20 for example. If you have a good Group IV oil which can tolerate higher temps than group III, you can potentially use 5w30 or even 5w20 if you are not always stuck in heavy traffic. Using the recommended oil for your engine that is group IV is better for fuel efficiency, a lot smoother idling (almost like brand new for decade old engines) and longer lasting variable valve components. You can rev up high too without smelling any burning oil.

  2. is motul 7100 20w50 a Group 4 or Group 3 engine oil.......which are the brands engine oil can i find in the Group 4 synthetic oils with 20w50 grade ???

  3. If you look at the Safety Data Sheets, these oils look like they are made up of hydrocracked refined hydrocarbons or group III. Nothing shows Group IV (POAs or Decene) or Group V!
