My bike comes with a cat-con and I think putting SJ oil isnt good for it.
Yamalube is SL. So what do you recommend?

no problem buddy. My car also comes with cat-con, oil used till 85k was API SG/SH no problem till date.
also all hero/honda bikes are recommended for API SJ they also comes with cat-con.
Btw, cat-cons can last more than 2-3 lakhs kms!! (just dont burn oil in your combustion chamber)

Yes & No , you can't guarantee genuine like buying from yamaha's own parts counters . I'm scared of fakemongers too like you and have taken a different approach . I called up motul's regional manager here and asked him to guide me to a dependable authorised shop/dealer near me ... which he gladly did .
Motul 3000 4T plus claims to conform to the API SM rating (2004), which is a higher/newer standard than the SL (1998), so it's supposed to be even better for your cat-con . However, neither yamalube or motul bears the correct API certification symbol , but both have the correct JASO certification , yamalube is JASO MA and motul is JASO MA2 .
I have compared the packaging of both yamalube and motul 20w40 oils and you can see it here http://www.xbhp.com/talkies/629271-post3663.html

A note about API/JASO ratings printed on oil package :
Many oil manufacturers here doesn't really send their oils to the American Petroleum Association's/ Japanese JASO labs for testing & certification . But they print on the product bottle "conforms to" "exceeds the requirements of" "valve-train wear less than" API standard SL SM or JASO MA2 etc etc so and so, taking advatage of our lax laws in the matter . Some also use a fake API-like and/or JASO-like symbol to mislead the buyer as shown below . A real tested in proper labs oil shall bear a certification with number and correct symbol of API or JASO .
An API certificate looks like this -
And a fake one like this -
A real JASO certified oil tested in japan & certified shall bear this symbol and certificate numbers like this -

Many oils marketed here does not bear any of these symbols , just a written claim that it does conform to so and so . Sometimes not even that . Motul's CNG/LPG engine oil 20w50 is one example of such non-tested oil . But unlike castrol , they do not make any compliance claims on it . The situation is very murky and unscrupulous to say it mildly .
It would be very unlikely to find an oil that bear both the symbols simultaneously , i.e has been tested both in the USA and in Japan . So for motorcycle usage , it's sufficient if you just look for the correct JASO certification symbol and number , and take their API conformance claims with a pinch of rock-salt or other digestive substance .

Thanks a lot Pinaki Sir, I liked the comparison of Motul against Yamalube. I will surely be going for Motul hence forward.
I agree its more unlikely to find an Motul fake as against a Castrol fake. So I will make sure to buy from a decent dealer for the oil.
Perhaps the reason these come with clear JASO certification is due to the fact that these oils go into Japanese bike engines?

then bike must be used in the bracket of a given temperature range, which i believe is 35'C to 42'C.
But then also i dont think monograde oils are JASO MA neither they carry needed detergents or additives, hence not recommended for bike engine.

I used Motul FS 15w50 and the viscosity decreased within 500KM leading to vibes... What options do I have?

I've used this on my P135. Certainly better than mineral oils. No leakages!. And I think it is original.

Ok. Thanks for the assurance. Will use it next
