18 wrz 2020 · JASO MA2 oils offer increased frictional performance, allowing oil manufacturers to finetune their formulations for added performance in specific areas, depending on the application. If all three test results fall within MA1 parameters, the oil can be classified as a JASO MA1 oil.
The motor oils that meet the JASO T 903:2006 standard can be classified into four grades: JASO MA, JASO MA1, JASO MA2 and JASO MB. The classification is based on the results of the JASO T 904:2006 clutch system firction test.
1 wrz 2015 · If all its properties fall within the limits of MA2 then it can be classified as a JASO MA2 oil. If some properties fall within the MA1 subcategory but others in MA2 then the product is simply a JASO MA product.
3 gru 2023 · Ma2 engine oil beat Jaso MA2 oil and more critical information. From here, you also can know which oil certifications are best for your motorcycle and scooter. The JASO MA/MA2 specs ensure enough friction to help with shared wet clutch applications.
