Thanks a lot buddy...But can you tell me how is castrol power 1 compared to petronas Sprinta..? and whats the price of the both..

Are you talking about Castrol Power 1 or Power 1 Racing? Since the former is semi-synthetic&the latter is fully synthetic. I have not used either of them. Many others are using it. The fully synthetic one is very good. It costs Rs.750 approx. per litre. There are quite a few reviews here by senior members, you should be able to get the links from the main page itself.
Myself&many others are using Petronas Sprinta 4T 5000 in Hyderabad. We order for a crate, so get it at a cheaper price. MRP should be around Rs.350. So, cost wise there is too much of a difference&since both are fully synthetic, I felt that Petronas will be a better bet for my 5 year old Fiero F2. There is no decoloration even after 1500kms. I expect it to last around 5-6K kms. A topup may be required midway though.

i just have one simple question .. which grade is thicker .. ?
20w40 or 20w50 .. ?

20w50 will be thicker. A bike for which 20w40 oil is recommended, will take 20w50 or even 15w50 for that matter, but the reverse does not hold true i.e., If the recommended grade is 20w50, you can go for 15w50, but not 20w40. It will cause clutch slipping and other problems.
Read the first few posts of this thread by Sandeep K Ram. Everything will be crystal clear!

Is there any need of cleaning or sort before changing the oil to synthetic or semi synthetic from mineral?

Not needed,but if ur bike is more than say 10k kms old, i would advise to get the centrifugal filter cleaned. U may also do an engine flush if u want.

Thanks buddy u come to save me everytime in dilemma

Ya my bike is more than 50k old and what is this centrifugal filter-is it the oil filter?
So I hope an engine flush is actually not necessary?

Yeah man, it is an oil filter. TO clean that, u have to remove the engine casing(right side). Bajaj morons would say that it is not needed, but it is a part of regular servicing,(10k kms) so make sure that it is done!

And yes, if u just clean the centrifugal filter it is enough.Flushing is advised when u feel that there is some carbon deposit inside the engine.(Actually Bajaj recommends De-carbonising the engine every 30k kms).

Correction: Its present in other bikes too..but i guess its not in P150..!

okei, I have decarbonised the engine and integral parts at 40k km's on odo so hope that won't be needed.. and about oil filter I don't remember cleaning it, so will have to clean it I guess

thanks again buddy

Mr Inder, should i scan the manual and show it to you?

@Nio : U are welcome bro!

Change the oil filter&clean the centrifugal filter if there is one.

I am repeating this time and time again, there is no conventional oil filter(like in the R15,RTR,etc) in any of the Pulsars. There is only one Centrifugal oil filter. It is to be cleaned and not replaced!

Oh, I didn't know that! Anyways, is it a lifetime filter? If yes, then cleaning interval must be written in the manual.

@Nio: Please ensure that it is cleaned throughly as you are shifting over to a different type of oil.
Don't ask us about the residual 200ml of oil left inside the engine. You will have to open up the engine to remove that! It doesn't matter at all, the mixing will not cause any harm. Later if you don't get the same oil, you can even topup with a mineral oil, small mix won't create problems.

Ya I know that, I usually change my oil every 3k kms but this would be the first time I'm experimenting with a new grade oil; thats why asked about the cleanup...
though after removing the leftover its strains would be left in the engine right? that's why I needed to know If it would cause any mixing problem with The new oil which would be of different origin and grade..
Guess it wouldn't be a trouble if I clean the filter before the change

I knew this would be the next question, so I already wrote the answer-no problem if minor quantity gets mixed!

I've Ppl often say that xyz oil is good & that they see no discoloration of the oil even after 1000 Kms!!!

How is dat possible , isnt not engine oil supposed to act as a cleaner as well , cleaning up all carbon deposits etc......

When i change my oil .it changes to muddy & then quite dark after couple of 200-300K's .....isnt that normal ...or am i missing a point here
