Engine Oils

[FranklySpeaking]

One thing that I've noticed is that oils by the PSU's (Indian Oil, HP) are not JASO MA. Recently I went to Hindustan Petroleum pump and looked at the oil bottles, none had JASO MA on it. And they were multi-purpose oils. The same oil had photo of a 2 wheeler, 4 wheeler and everything at the back. I am using that oil in my Pulsar now. Probably they dont bother using friction modifiers in any of their oils, hence the same oil can be used in everything? Or they just dont know of clutch slippage or anything in bikes?

I am using Castrol GTX, which is a car oil in my Bullet's engine. In clutch case, it is the JASO MA Hero Honda oil that goes in.

Obviously they won't be because these are Indian made & will not send to Japan to get them certified from JASO.

Honda = Japan & since Castrol isn't an Indian company; but I wonder how Castrol is bothered to obtain JASO instead of ACEA!!!

I also mailed shell india asking whether i can use helix ultra in motorcycles.

hope they reply.

aargee... Earlier i was saying this only. But as i read long back i dint get the term correctly. now got... its friction busters making clutch slippage which damages clutch plates

What does Indian-made have to do with not having a Japanese certification?

It's another thing that the PSU's probably would not bother and use the same oil in everything.

@Andante - Tks for the explanation; though I've read it twice, it will take a while to get onto my head. I'll understand them thoroughly & get back to you for any questions.

But I would like to add a point here that JASO is another certification like API or ACEA. The difference being that JASO is Japanese standards, API being American & ACEA is European standards for engine oil. Check out Shell or Mobil, they will not be JASO certified.

I used to use the good old JetX from Castrol that used to be JASO, IIRC, it contained FC standards. Good Thanks to the Govt to have smoked out 2 strokes & ever since then JetX is being unavailable & hence all these confusions.

Yes, JASO is just another standard, but it happens to be the one standard that meshes well with a wet clutch. API used to have ratings that were compatible with wet clutches, but ever since they started added friction modifiers to the standard it became incompatible. Thus the need to JASO MA. There is also JASO MB rated oil, which is essentially the same as a car oil with friction modifiers and not suitable for a wet clutch.

And yes, it's quite possible to encounter oil that does not have a JASO MA certificate, especially oils from the indian companies. However, it's quite possible they use an old (or even very old) API rating and thus being compatible with wet clutches.

Anyway, YMMV. Use what you think is right, but try to use an oil for which the manufacturer endorses it as a bike oil. (Which Shell Helix is not, it's a car oil.)

I need some suggestions on engine oil guys.

My ninja went through only one oil change at 1000kms and after my discussion with a few premium bike owners I feel i should change to semi-synth (at least). I plan to do the oil change at least once every 5k kms and the oil filter once every 10k kms.

Considering the temperatures in blore, I have decided on the below oils from Motul. These are good for Immersed Clutches (wet clutches) and meet the following standards: API SL / SJ / SH / SG – JASO MA.

I was thinking of going in for Motul 5100 15W50 or Motul 5100 10W50. According to the manual the recommended oil grade is 20W50.

Which is recommended for Bangalore weather? The summers dont get hotter than 38 deg celcius and winter doesnt get colder than 15 degrees celcius.

But also consider that i might be touring to hotter or colder places.

I do not want to switch to fully synthetic as i feel semi synth is good enough.

Also do i have to use an engine flush since the factory filled oil is mineral oil and I am switching to semi synth now? I prefer to flush the engine so where can i buy a good brand of engine flush in blore?

Replies will be greatly appreciated. I am planning to do the oil change next saturday. Initially wanted to get it over with this weekend but I am working on saturday and the service center is closed on sunday.

Didnt know that something like Motul 7100 exists. Is it SS or FS?

according to the site it is FS,what about 5000?

[chicane1879]

Havent heard of that too. Are they available in India?

The only one you can find around is 30004T, 5100, 300V.

Yes 5100 is a SS and also would go well with the P150!!

Yes, you can use 15W50 instead of 20W50, wouldnt make much of a difference. It would infact be good in winters.

There is no need to flush. Flushing is fart. Semi-synthetic is more than 70% mineral oil anyway. Just drain and use any oil that you like.

I agree with the flushing bit. But while moving from Mineral to SS or FS (or any other such combination), a change of oil-filter is necessary though, right?

i have changed from yamalube (mineral) to agip racing (synthetic) without any change of filters or engine flushing. Didnt faced any problem yet.
