Re: Engine Oils

even here in the SVC the oil comes in a drum...but outside at local shops if u are lucky..u can get a 1/1.2 litre dtsi oil bottle....theres even a photo of that bottle in the p200NS manual

why do u not recommend mixing engine oils? their grades are almost the same isnt it?
[MENTION=47870]devils_friend[/MENTION]

the manual clearly mentions that failing to change oil to bajaj oil will result in lapse of warranty

and no i am not lazy...infact i want to change the oil myself using tools and DIY stuff

okay i'll change oil after coming back from the vacation...
after vacation oil will be about 5 months old...and i might need the bike immediately...wouldnt it be fine if i change oil after a day or 2?

Well, i guess you have to stick to bajaj oil to keep your warranty (if you want to).

The best practice is to change the oil by 70-75 days period or at the correct drain interval. The oil will be 5 months old by the time you come back, of which, oil would be absolutely stable for one month when you are out. The viscosity of the oil will change to thicker side. Also, you will definately feel some lack in performance with such oil.

Cheerz!!

It's just a matter of reselling. If a guy has good rapport with any showrooms or oil distributors they can resell Bajaj oil. After all you get most manufacturer branded oils elsewhere like HH, YAMALUBE etc. So it isn't a big deal.

Re: Engine Oils

mixing different brands and different grades are two different things. I hope you meant the latter. You can mix similar grade oil say 15W50 of Motul 3000 with 15W50 of Motul 5100 that does not make any difference and since the manufacturer here is same the production process for both oils should be same. Mixing of 15W50 grade oil with a 20W50 grade is what is not recommended. I dont know the details or the actual funda behind it but the only thing i can think of now is the thickness of both these grades are different, hence they might now mix well.

when you say change oil after a day or 2 you mean after come back from vacations or after the service. I recommend after you come back from vacation.

Experts opinion in this regard awaited. Pinaki, PSR, muz, Back7Thorn ........

Mixing of same type of oil with slightly different grades will not harm the engine....
There are Two School of thought on this subject...
The Purists are dead against this, while the survivors are all for it.....
If the oil level in the engine is low, then whatever you can get to top it to correct level is good...but if you are going to experiment for the sake of learning, then it is not adviceable to do so....The type..Mineral/SS/FS ..You can mix SS or FS into Mineral without issues....as long as you observe it is with or without Molybdenum disulphide.....
Mixing different grades ..20w40 with 15w40 is permissible......mixing of 10w30 with 15w50 or 20w50 is not good, since the base stock variation is larger ...and the additives are different ...
It all depends on whether you are stuck with low oil in a place where only low quality(re-cycled) 20w50 oil is available and your bike has 10w30 FS, then all theories are Kaput..You have to first save the engine and adding a low grade 20w50 to a 10w30 FS is the ONLY alternative....

Re: Engine Oils

@psr

No i am not stranded anywhere nor i have low engine oil level...

My query simple

since this bike comes factory filled with SS and once @muztariq mentioned in the thread it is always better to use SS or FS in such engines which have high compression ratio and rev high than normal...


I just wanted to ask for my next oil change i have 800ml of motul3000 mineral 15W50 oil...

now we all love our bikes and want the best for it(it doesnt mean i am going to put FS oil and drain it every 1000km)

got confused between 2 different thoughts
mustariq said better to us SS/FS in such engines(i do not understand the concept a FS/SS/mineral oil of same grade will have same thickness and viscosity when maintained in the same engine at same temperature)
and @Pinaki says better to use cheap mineral and maintain quick drain intervals

so now i am running on the mineral motul oil i mentioned and have 800ml of it left..

i know motul mineral oil is better than the bajaj dtsi SS oil which comes in the bike from factory and i am also aware that during my oil change when i shifted to motul 300 !%w%) i have indirectly mixxed a 20W50 stock bajaj in the oil sump with fresh 15W50 oil

so for next oil change should i go ahead and continue the motul mineral or just as an experiment if no harm happens can i mix the motul 3100 SS oil which has a grade of 20W50 compared to 15W50 of motul 3000


and if mixing is fine then what proportion of mixing? since i'll have to buy a new 3100 bottle and i'll have 800ml of motul 3000 and 1litre of motul 3100

Re: Engine Oils

Tried in some shops but failed to get.

I want a shop in Mumbai selling 4Litre or 5Litre can of Motul 4T 5100 20W50 for Pulsar 220.

Is there anyone ?

You can get 4 or 5 liter only in 4-wheeler spare part dealers as bikes don't use that quantity. Logic. Try Pioneer Automobiles at BEST Nagar, Goregaon West. You are more likely to get Mobil or Mobil1 though, as they are more commonly used in cars.

Re: Engine Oils

^^^
You're still not getting the point Mayank. What proportion? What is the recommended 1.2L is what's recommended for NS right, add the remaining vice versa if you intend to use the 3100 in the next oil change for if you intend to use the 3000 then top up with 3100.

Just for gags though, psr ji, doesn't like to be pestered on silly questions.

Re: Engine Oils

Yes 1.2 litres...I got the point....i do not mind using any oil next time...if mixing works i might use the mixture next time too(depending on what oil i am left with)....just wanted to know technicalities behind it... wanted to hear from all regulars in this thread who have a lot of experience... think of me as a noob doing his own mini mixing experiment.... i think i'll stop pestering ppl in the thread with my questions thanks

I dont think I took high compression ratio and high rev engine into account when asking ppl to stick to SS/FS oils when the engine came with SS/FS factory filled.

Its simple, engine designed for SS/FS oils needs to run on them. Manufacturers are creating their own spec for oil just to ensure that the oil meets the standards which is bare minimum for the engine they made.

Also read somewhere that Bajaj 10000 DTSi is SS.

Regarding oil mixing, I think that is over-discussed here. I ensure minimum oil mixing. I would leave that to you how you do it or dont do it.. In the practical world it hardly matters, we just try to minimize risks.

Re: Engine Oils

There is a shop in borivali who sells Motul oils. But, not sure whether they stock on big cans or not.

Where do you stay?

Cheerz!!

Sounds great! Does he stock 10W40 grade SS? Please let me know. The dudes around my place only have 15W50. Also give some details of the address of the shop and name. Thanx in advance. I stay in malad so can access borivali easily. Anything for motul :-D. Cheers!

I guess its available in AH helmet also.


But I never get the reason why all the shops selling Motul on exactly the MRP !
And the reason is "This is Motul"!

The hell ?

No probs....A higher base number or number after W will mean a thicker oil which will make your engine slow to Rev....ie., a 20w has thicker base oil than a 15w or 10w..similarly w50 is thicker than w30 or w40.....
Stick to stock recommended Grade of oil for safety, esp., during hot climate.
An engine with larger tolerance of machined parts and or /producing higher temperature ,require a thicker grade oil..and an engine with closer tolerance in machining of parts can work with thinner oil...
Regarding choice of Mineral or SS or FS...the choice is as per Manufacturer and yours..
I have never used SS or FS in any of the engine of Vehicle I had owned...I use Mineral oil only and change them at 1,500 Kms for 4 stroke, and 3,500 in two stroke bikes....In cars I change oil at 5,000 Kms or ONE year which ever is earlier..

Re: Engine Oils

thanks for the help...i guess i understood the point very well and will stop th discussion on mixing..

@mustariq
i am not sure but i guess you mentioned modern engines which now a days do have higher compression than before...

but i guess thats my bad i took it the wrong way

how do we know an engine is designed for SS or FS oil?
what will happen if i use mineral?

an oil of same grade will have same viscosity at a particular temperature irrespective of its make(SS,FS,mineral) isnt it? its just how long they can hold their property which differs in the type of oil FS>SS>mineral right?

then i do not get the concept of vehicle engine designed for SS/FS oil

the engine is designed and a grade of oil is suitable to it and not the type of oil right?

yes bajaj dtsi oil is a SS oil and most of the members here using the SS oil believe its just name sake SS and nothing extra ordinary....
many even said good quality mineral oil is beter than bajaj dtsi SS oil

He has got all stocks of motul no matter what. I mean, almost all motul products are there. The guy out there has some good knowledge with regards to oil and bikes.

Come down thru rajendra nagar zoom on the rajendra nagar. Go straight from the signal. One more signal will come, go straight from there. Go ahead and you get one more signal, take right from there and wolllaaaahhhh on the right side of the road you see Motul signboard and thats your destination my boy. You need to take a u-turn to get to the garage, since the shop is on the right side of road.

Hope this helps :thumbup:

Well, higher CC engines can handle SS / FS oils. Smaller CC engines dont require such oils, since they dont run on high RPM's and dont produce the same amount of stress, heat on the engine. Whereas, higher CC produces greater stress and heat. For this, SS / FS oils will serve the purpose well.

Mineral oil can be used. But, you will feel the difference when you ride on SS / FS oil. The drain period of mineral oil is on the lesser side as compared to SS / FS oil. The grade and type of oil plays and important role to keep the tolerances in the engine. The type of oil will help in many ways, like heat rejection, smooth gear shifts, engine parts protection to name a few.

If a company recommends 20W-40 (mineral / SS / SS) oil for its engine. This is because, they have designed the engine keeping in mind the oils performance in the engine.
