What does JASO MA2 mean?
What does JASO MA2 mean?
JASO MA: This is the standard specification for oils that are used within one oil system (where the engine, gearbox and clutch use the same oil). JASO MA2: This is a higher standard specification for modern motorcycles. These oils are suitable for use in motorcycles that have catalytic converters in the exhaust system.
Can you use MA2 oil instead of Ma?
Most motorcycles and dirt bikes use the same oil to lubricate the engine and clutch. Instead, you need to use a JASO MA or JASO MA2 oil.
Can I use JASO MA2 instead of MB?
Means JASO MB cab be replaced by JASO MA. Because it just has more anti clutch slippage additive but will not do harm to engine. JASO MB is not a replace for JASO MA. Because the fuel efficient additive may cause the clutch to slip or has severe wear.
What is JASO T903 MA2?
The JASO MA2 rating was introduced in the 2006 JASO T903 standard for modern motorcycle engines. A JASO MA2 oil is simply a motor oil that meets the JASO MA2 rating. A 4 stroke motorcycle oil. Primarily used for wet clutch applications. Suitable for a motorcycle with a catalytic converter.
What oil is safe for wet clutch?
The key is to use a lubricant specifically formulated for wet clutches, such as AMSOIL synthetic motorcycle and dirt bike oils. They contain no friction modifiers or extreme-pressure additives.
What is a wet clutch?
A wet clutch transfers power through mechanical and fluid couplings by mating rotating friction plates immersed in lubricant. Wet clutches are typically used in a compact and lubricant-rich environment, such as automatic transmission (Deur et al.
What is the meaning of SAE in oil?
Therefore the first three letters you need to know are SAE, the acronym of the Society of Automotive Engineers. This society is responsible for establishing a classification system based solely on oil viscosity. An oil with a low SAE W number will flow better, making cold starts easier and reducing engine wear.
Why TVS Motors only recommended the JASO MA2 engine oil for all gearless scooters instead of JASO MB?
Because it just has more anti clutch slippage additive but will not do harm to engine. JASO MB is not a replace for JASO MA. Because the fuel efficient additive may cause the clutch to slip or has severe wear.
What is the difference between MA and MB engine oil?
JASO MA – This was the standard for single unit engines where the wet clutch, gearbox and engine used the same oil. 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 is JASO T903?
JASO T903, the global motorcycle lubricant standard, specifies an important split that sets critical performance attributes necessary for motorcycles requiring low friction and high friction lubricants. Today’s lubricant technology has evolved for specific performance benefits in many unique applications.
Is synthetic oil bad for wet clutch?
They can be synthetic, synthetic blend, or mineral. Never use an oil without the MA2 rating in a wet clutch application. This includes cars like my Morris Mini, where the engine oil is used in the automatic transmission.
Can you use synthetic oil in a wet clutch?
Unfortunately, automotive motor oils for gasoline service; both synthetic and conventional, contain friction modifiers. Simply put, friction modifiers are incompatible with motorcycle wet clutches. They will cause the clutch to slip under load and eventually glaze the clutch plates.
