whats the difference between JASO-MA and JASO-MA 2? saw both at the store.

 

New JASO oil standards (MA1, MA2):

JASO effectively added the JASO-MA2 & JASO-MA1 specifications by splitting the existing JASO-MA spec into two groups by friction-performance (MA1 is the lower friction oils; MA2 the higher friction oils suitable for bikes).
The change came out as final/approved in 2006 in response to catalytic converters becoming widespread in bikes (EPA/EU requirements); it was also prompted in part by the car-lobby of the JASO organization wanting to specify a subset of the JASO-MA oils for use in their cars (the low friction oils, which become JASO-MA1). JASO-MA2 is just starting to show up in the US Market as a rating because this is the first year that catalytic converter-equipped bikes are widespread.

Aside from splitting the MA spec into two sub-groups, the new specs add a phosphorous content ceiling (better protect catalytic converters by using less, but phosphorous is also anti-wear additive, so it could be less start-up protection). JASO-MA2 being the heavier friction oils most suitable for motorcycle use will become the common standard for Japanese-built (and many Euro-built) motorcycles for the '08 and later model years.

 

You can get Amsoil delivered to your door as cheap, if not cheaper, than you can buy it at the store.... AMSOIL Synthetic Motorcycle Oil

 

Ok so if I have the choice go with the JASO-MA2?

 

if your bike is newer than 08, yes. if not, either is fine. shouldn't hurt either way. i think most motorcycle oils will become labeled as ma2 anyway. ma just means it was labeled before the split into ma1, ma2.

 

I got my 94 @ 24K still running strong as ever...TLC and she'll be fine...but note some maintenance may be due...soon like fork seal, sparks, filter etc...so when your not sure if previous owner change it or not? Just upgrade...like my spark plugs, when I first got her, I don't know? Chit, just replace them with Iranium plug...fire right up!!! Don't know what oil? Get her fresh ones...

Oh...post some
Pic...of your newly May, purchase bike..

 

As was said, MA2 is the highest friction, MA1 is next, and MB is lowest of the three.

The statement that OP found somewhere on the 'net about there being no phos limits on 10W30 oil is flatly wrong. 10W30 has had a phosphorus cap since at least API's SH classification.

Motorcycle-specific oils aren't even close to the 'only' ones with JASO MA frictional properties, though. Nearly every 'diesel' or 'all-fleet' oil will have frictional characteristics that fall within JASO's MA limits. That means Rotella T, Delo 400, Delvac 1300, and so on.

Here's the JASO specification paper, if you're interested:

well this is what i just put in mine.

 

plus thats all they had

 

This sounds like something that a sales rep from a dino-oil manufacturer would say to discourage you from using synthetic oil. Too funny! It's never too late to switch to synthetic oil. But, you don't need to spend $10 a quart on it.
