Manual says JASO MB 10W30 on a HONDA SH 150 2025 model

Is dry clutch CVT, with NO oil filter (just an oil screen) and takes 800ml.

If I add JASO MA/MA2 is there any PROS and CONS ?

Same oil says needs for the gearbox (seperate) JASO MB 10W30

Thanks in advance

Here, this is the oil for scooters with CVT or dry clutch:

You might be fine with JASO MA/MA2 too. The correct oil is the one above. However, if you cannot find it, you can use this one which is JASO MA2:

Either of those oils should be about €15 - 20 for a liter.
I already see them, many thanks

But what is the difference in additives JASO MA/MA2 VS MB

The percentage on Molybdenum ?

I'm not sure what is the difference regarding formulation ingredients. It probably has more friction modifiers like molybdenum which will be good for the gears, but not for a wet clutch.
However, the main difference is that JASO MA/MA2 is for wet clutch applications and JASO MB is for gears only (CVT) and not wet clutch. But most likely you'll be fine with JASO MA/MA2 as well.

For example, this motorcycle gear oil, regardless that is synthetic blend, is not JASO rated, however it's API GL-4 and is for wet clutch too. It also might be a good and also a cheaper option. It's very popular among scooter and 2-stroke riders that have separate engine and gear oils. So, this oil is for the grears only, not the engine❗

However, it will be a bit thicker than 10W-30.

A scooter engine with a dry clutch does NOT need to use dedicated motorcycle oil! this question gets asked over and over on forums. Motorcycle oil is for a shared sump with a wet clutch. With a dry clutch you can use just about any quality oil that you feel like.
Well, then why don't you use motor oil in your car's gearbox/transmission and vise versa?
Cars have dry clutch, right?

indeed,no wet clutch like cars

So any oil is OK for the engine with the same viscosity 10/30

That’s a another question about manual calls for 10/30 MB also for the final drive gearbox

But as you said GL4 rating should be ok also for wet clutch, so I don’t understand why they don’t add alternative option in the owners manual

Many thanks
