What is JASO T903 MA?

JASO T903 establishes two performance categories: MA for motorcycles fitted with wet clutch and MB for motorcycles fitted with Automatic transmission (Scooters).

Is Castrol oil good for motorcycles?

Most motorcycle engine oils are designed to improve your bike’s acceleration by improving the engine transmission quality. However, very few products can match Castrol. The Castrol 06112 Synthetic Motorcycle Oil, through its unique oil blend formula, allows for superior acceleration at the touch of your throttle.

What is JASO MA and MB?

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).

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.

What does MB mean in oil?

million barrels of oil equivalent per day.

Can I use JASO MB in wet clutch?

Use with motorcycle with wet clutch will result in poor performance, though. JASO MB is suitable for motorcycles that have a separate lubrication circuit for gear/clutch and for the engine. The engine oil can be optimized for lower friction.

Can I use JASO MA instead of MB?

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. JASO MB: This is a lower standard specification for scooter engines.

What is the difference between motorcycle oil and automobile oil?

But the key difference between the lubricant requirements of a motorcycle oil versus a passenger car oil is where the oil must protect. In a car engine, the oil protects only the engine. Passenger car motor oils also contain friction modifiers which could lead to slipping and acceleration loss in a motorcycle.

Can I use JASO MA2 instead of JASO MA?

TL DR: Using JASO MA2 oil should work just fine for you. The JASO MA Motorcycle oil standard is: Japanese standard for special oil which can be used in 4-stroke motorcycle engine with one oil system for engine, gearbox and wet clutch system. Fluid is non-friction modified.

What is JASO MA2 engine oil?

Overview. JASO MA2 oils are formulated to deliver higher clutch frictional performance. They are designed for use in four-stroke motorcycles and scooters and are primarily suitable for wet-clutch applications.

Can I use API SN instead of SL?

API SN to SJ are for the most recent cars, API SH to SA for the older cars. In this case, you need API SL, so an API SJ, lower, cannot be good. SM and SN supersedes SL so both oils can be used.

What kind of oil is in Jaso t903?

Furthermore, JASO T903 is now broken down into four categories: MA, MA1 MA2, and MB. JASO MA: This standard specification is for oils that are used within one oil system (where the engine, gearbox and clutch use the same oil). These oils don’t contain any friction modifiers.

What are the grades of Jaso motor oils?

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.

Can a JASO MA oil be classified as MA1?

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.

Do you need JASO MA oil for wet clutch?

The oil must exhibit the correct frictional properties or else the clutch can slip. 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.
