What oils are JASO MA rated?
JASO MA: This is the standard category for oils used within one system (where the engine, clutch, and gearbox use the same oil). MA oil has no friction modifier….3. What Is JASO T903?
| JASO MA1 Oil | JASO MA2 Oil | |
|---|---|---|
| STI (Stop Time Index) | ≥1.40 and <1.60 | ≥1.60 and <2.50 |
What is Ma engine oil?
JASO MA – This was the standard for single unit engines where the wet clutch, gearbox and engine used the same oil. JASO-MA oils don’t contain friction modifiers. JASO MB – This lower standard was for bikes that use separate oils for the engine, clutch and gearbox (e.g Harley Davidson’s and BMW’s).
What does API SN mean?
The codes are as follows: • SN: For vehicles manufactured after 2010. • SM: Vehicles manufactured between 2002-2009. • SJ: Vehicles manufactured before 2001. Diesel engines: The first letter, C, indicates the oil is for a diesel engine.
What is the difference between Jaso MA1 and Jaso MA2?
If all three test results fall within MA2 parameters, then it can be classified as a JASO MA2 oil. If some results fall within the MA1 subcategory but others fall under MA2, the oil is simply classified as JASO MA. Why the need for JASO MA2? JASO MA2 oil provides increased friction performance – essentially, more grip.
What are the different types of JASO MA oil?
The JASO MA range is further divided into 2 distinct ranges – the JASO MA1 and JASO MA2 ranges – as follows: If all three properties of a JASO MA oil fall within the limits specified as MA1 then the oil can be classified as a JASO MA1 oil. If all its properties fall within the limits of MA2 then it can be classified as a JASO MA2 oil.
What is the JASO MA standard?
JASO MA – This was the standard for single unit engines where the wet clutch, gearbox and engine used the same oil.
Can you use Jaso MA2 oil in a wet clutch?
Since passenger car/light-truck oils often contain friction modifiers to improve fuel economy, they aren’t recommended for wet-clutch applications. Instead, you need to use a JASO MA or JASO MA2 oil. The JASO classifications can get a little confusing; let’s break it all down.
