please advice me (havoline, valvoline, castrol active and tru4 premium are only available here).

Yes there are two oils. Castrol Activ 20w40 and Activ Xtra 20w50 both are fully synthetic. Both oils are good, even though I call them Crapstrol, you can use them. You can use with no issues at all. I mean it's basic, they do their job well, but too well, well....

Yes you can, but you need to make sure the engine is flushed. But I don't think why you should revert to mineral once again after the engine has already run on SS, unless you've rebored your engine.

Are you sure on that ? AFAIK,it is a semi synthetic oil .

I don't think there is any strong reason to flush the engine oil unless he plans to use a expensive Fully Synthetic oil and does not like the FS to get mixed with the old oil.
At-least I never had any problems by not flushing the old oil before switching to a different grade/type of oil. It depends on the engine,quality of oil used and frequency of oil changes.

Just my opinion .

I go by their website, I think it is synthetic for most part. They haven't mentioned semi anywhere, as even I used the 20w50 Activ Xtra it just says synthetic technology. Perhaps it might mean, they are semi-syn or fully syn, but seeing in their website, at least I reckon it's fully synthetic.

Some websites even state the same oil as Mineral, I don't understand how an that clearly states SYNTHETIC TECH will come under Mineral unless it's semi-sync. But even my dear heart tells me it's just semi and the SYNTHETIC tech is just a gimmick.

You are right that it is a gimmick because we don't have strict rules as to what the companies can label on their products.Many companies mislead their customers by giving a false impression about the product
In-fact we cannot even tell how much part of a oil must be synthetic to call it as a semi synthetic. Even a oil containing as little as 2% synthetic oil can be called as a semi synthetic or can say on its label "with synthetic technology"
Now tell me how is it possible to manufacture a fully synthetic oil for Rs.250 ? Except Power 1 racing,all other motorcycle oils by Castrol is either SS or mineral.

Honestly I have no idea, and you're absolutely right with the addition part, just a trace would mean synthetic. It's just not snythetic that itself is costly. I mean, Power1 is "as they say" race derived has numerous other additives added to it, so the price can/shall/may be justified for that.

But you see, me no Castrol clique, I can't comment on the pricing.

^ same thing is mentioned many pages back.. Its one of the ss oil containing least amount of synthetic molecule(s). And definitely not the best oil.

Exactly. It's one of the worse oil I've used. No smoothness whatsover, it's just made the engine sound like a rattle snake, rattling!

which is the best ss oil and what grade for disc 100
and is it worth the change from mineral oil
will it cause clutch slips

I think I've answered your query back. Please go back a few pages. Castrol, Valvoline or Mak will be good proposition.

best ss oil for me is motul 5100 10w40 & 15w50 both grades. (though pricey) Second on the list 'are' valvoline premium 4t (its 20w50 only) and shell ax7 its only available in 10w40 [but both the oils are best vfm ] and no bike oil, i.e. A oil with JASO MA or MA1 or MA2 will make your clutch slip unless your clutch plates are worn out. And one can shift from and back to mineral, even if he/she used full synthetic oil. Regarding your 'worth' question only you can answer that, most ss oils cost around 300 (not below that) but lasts only 2000-2500kms max i.e. Similar to mineral oils. Ss only score ahead of mineral in terms of smoothness. All i can say is use it once and answer yourself

Let me clear some air here. Castrol Activ 20w40, Castrol Activ X-tra 20w50 is if my memory serves me right is when I bought it, clearly read synthetic technology. Now I myself came to a conclusion it must be semi-sync as I've quoted numerous times to a lot of members, including my mechanic.

But I happen to be going through their website and then found this contradicting info, so perhaps it must mislead me fooling for a correct info for bad. But some even say it's Mineral, which I clearly rule out, at least to my knowledge.

Here is two facts. First it can be a Mineral with trace amounts of synthetic, or a fully synthetic, no one for sure knows that, because no one is gonna add so called " Its specially formulated heat protection molecules" in a mineral one. Either it's gotta be semi-sync which I highly come to a conclusion or synthetic for that matter.

It's a real blooper to know that even after me using the oil, still discerning to know which grade is it, pathetically crazy!

^ whatever that castrol activ oil is. Its definitely not worth going for that. Many less talked mineral oils which is also quoted as 'mineral' works way better. Namely mak, servo, hp racer, valvoline etc..

That is same reason I name it as Crapstrol, after using most of their products, though Power1 is slightly appreciative

From quite sometime I have stopped reading the marketing statements which are written on the oil packs.
Firstly.. they are pure marketing statements and have no real meaning.
Secondly, they are of no use to me.

If the manufacturer recommends 20w40 or 20w50 grade and API SG, SL or higher. I just take the oil which meets these criteria with eyes closed. It is sufficient enough to give me the protection I need.. (may not be comfort).

The real problem arises when I want more protection.. more comfort.. extended drain intervals.. In pursuit of these extra(more) goodies I force early oil changes, buy SS and FS stuff etc etc.

Why will anyone buy a crapstrol even if it states 100% FS oil when after 500 kms the oil behaves dead.

Marketing the product with terms like magnatec will not make the oil great.. Triple protection.. enhanced engine life.. trizone etc are just marketting terms. All oils come with nearly the same formula.. the chemistry hasnt changed.

For example "its specially formulated heat protection molecules" can just be a term used for oil!! Engine Oil is a specially formulated liquid which protects the engine from heat build up.

All oil(chemical) manufacturers have to disclose the ingredients which they are using in their formulations. Its called MSDS. Material safety data sheet. Take a look at the various MSDS'es of various oils and check what all they have. Its more or less the same compounds.. same VII polymers.. same detergents.. same Zinc and Phosphate compounds.. same antioxidants..

Collect all the labels from various websites from oil manufacturers and all will read the same -

Sludge protection
Enhanced engine life
High temperature protection
Reduced oil consumption
Some will even say better mileage!!

Now whatever out of the world names you give them, the basics remain the same. If an oil is SAE 20w40 it has got all what it takes to become a good engine oil which will protect the engine all the time. Now if your engine is very new and made keepimg API SM rated specs and fitted with equipments like catalytic convertors etc it will not take a 20w40 SG rated oil. Though the oil is good enuf for the engine but for these equipments it is poisonous. That is the relevance of the Sx Ratings.

Bottomline - Just dont read the marketing statements. SAE, API, JASO ratings are sufficient for our vehicles.
For Cars, VW 505.00, 505.01, ACEA, BMW-LL-01 etc etc ratings further notifies the user which oil to use in which vehicle.. just a SAE, API SM/SN rating is not sufficient.
