Oil replacement for the original Thailand CBR150R which incarnated here with a different makeup and rear sprocket is suggested at the first 1000 kms. Next change is at 8000 kms and thereafter at the time of every alternative servicing which comes to 8000 kms.
And the oil recommended for that bike is 10W-30, not 20W-40. Please search on the net before crying to gather others around you for protection as if somebody is attacking you.

Yeah, recommended is 10W30.
But, from the price range of my first service, the oil ASC is using is FS and FS 10W30 is not available with Motul it seems. What to do?

With whatever "makeup" thai CBR is coming here, its is recommended in our manual to change oil with a interval of 2500-3000 kms.
Am saying this for the third time., and you trying to act as a "super-expert", quoting the 8000 kms interval for the second time here.

Will you read every post that at-least has your text quoted, or you would just reply to the posts that mock at you?
No offences meant, am asking this seriously.

I think punarvasu is either ill informed or trying to troll this thread. Whatever the case, best to ignore.

The 8k oil change interval is not for Indian model, or for Indian conditions (the latter is particularly important).

Don't believe Motul when they recommend 10w40 for CBR150 - what do you expect, they should be honest and say "don't buy our 10w40 because rating doesn't match"?

The rating is a measure of viscosity, in "10w30", it means the oil acts like a 30 weight while in operating temp. The second figures matter, going for 40 means the oil will be more viscous and not quite as free flowing (=less lubrication in parts where oil doesn't reach easily) as 10w30, that is not good for the engine.

For most bikes, I'd say, go for good replacement oils (I switched to Shell semi synth on my RTR160, for eg). But since CBR150R has 10w30 requirement AND comes with FS oil, I'd say stick with the Honda oil. Also helps you stay safe for warranty - remember, we're all buyers in the first year, even Honda (esp 250R) has quality issues in the first batch, that is corrected later. I'd not risk loosing warranty.

Read on some thread that CBR150R's engine is imported from Thailand. I didn't really believe it then, but today while on rider's seat and leaning over the tank, I noticed some non-English (Thai, I presume, but I can't read the language) letters on the radiator coolant lid. The only reason I can think of is, it was all built in Thailand and imported.

If that's the case, we know part of the reason CBR is priced 10k above the R15 - we know from Ninja and other bikes that imported parts make bikes cost a lot more...

I checked the manual and it says 10w30 (within a graph). Wonder where you saw 20w40? If it is true, then there is contradictory info. In any case, the ASC billed me for 10w30, so I think that's the officially approved one.

I checked the manual again, and it clearly mentions replace oil for each service, not top up. You quote a foreign manufacturer and say that Honda India's manual itself is wrong? Good luck convincing someone. 'nuff said!

I just checked the manual and it says 20W40. And yes the bike`s engine should be from Thailand as said by "punarvasu" . If its imported then the price is justified.

And Mr.Vasu, as you are saying that we are having Thai engines in our bikes, we are still driving it in Indian roads.



Betters tick with the Honda oil till third service as it may void warranty if u use other oils. And the 20 W 40 oil listed in the motul site is mineral oil. So we are out of luck.

Lol! Two owners quoting different grades. Its not to blame us brothers.
Inside the manual, they have given 10W30 and at the inside of back cover, it has got info on 20W40.
Checked the website and it says, 10W30 Fully synthetic oil is used for motorcycles.
So, ours probably should be 10W30.

@punarvasu,
I dunno if it is just me., the basic image of all your comments is that you try to mock at this bike, stating its a graded down version of Thai's bike and from the long back posts, its not worth for the money paid for. What you believe may be true, but, if you are trying to help the owners here, you are welcomed to just post regarding the queries and avoid projecting of your mind's image on the bike, as it would not be obviously welcomed here.

And regarding your statement of 8000kms interval, can you share the link from where you got that data?

I am not Punar + Vasu; just punarvasu. Don’t change my name as it is difficult to notify the change in gazette.
Isn’t it strange that the grade of engine oil to be used in a bike is shown differently in the same manual? And I didn’t ever say that it is the degraded version of Thai CBR150R. These were/are my main contentions:
1. This 150 cc bike is overpriced.
2. Its only differences from the original Thai bike are in the size of the tyres and number of rear sprocket teeth. Both these changes make the bike faster but more sluggish.
Other points were about its ability to accelerate faster, the maximum speed it can reach, error in the speedo/odo meters etc. I am not a man changing my words so frequently.
These are the links you asked for:
1. https://docs.google.com/file/d/0B0Ru...hl=en_US&pli=1
2. https://docs.google.com/file/d/0B0Ru...hl=en_US&pli=1
Hope it is useful.
I have clearly said earlier (reply No. 1729) that I am not sure about the oil change interval and asked neevarp16 to refer the user’s manual.

There has been quite a lot of discussion regarding oil grades for the CBR 250R in that ownership thread. Kindly go and search for it. Even our manuals have listed 20W40 and 10W30 with a chart showing which grade oil has to be used for which temperature. IF you live in a warm area the 10W30 is your priority. If you live in a very hot area, the 20W40 is an option(But not priority). But we at the 250R thread have come to the conclusion that 20W40 isnt required and it also makes the engine very sluggish at times. So we have all agreed to stick with the factory supplied 10W30 for now. Some owners have also used aftermarket 10W30 but im not sure if it would void warranty.

engine oil grade depends to an extent on the ambient atmospheric temperature.(that is one reason you will see a graph with temp / grade on most honda user manuals)
IMO 10w30 will be good for the indian 'winters' (i.e. the following few months) and you can switch over to 10w40 in summer. but If you ride hard or do higher speeds (over 80) consistently (highway riding), stick to 10w40 (or20w40) always (and remember to let the bike warm up for a minute before you take off)
Regarding what they use at a SVC, it all depends on what they are stocked up on (trust me they will tell you what they have is what you are supposed to use).

“And when he had opened the seventh seal, there was silence in heaven about the space of half an hour”. Revelation: 8-1.
Go through the links provided above, compare the specifications of Thai and Indian (?) CBR150Rs and decide yourself whether I was trying to mock this bike saying it is the degraded version of original or not.
It is a pleasure and great relief that all the participants in that debate agreed unanimously to use certain grade oil. It really is unusual.
All are asking for links as proofs. I guess these are helpful:

Fainting! Somebody please give me some water.

i can give you another 4 links if you want
But can let us know 'YOUR' understanding / knowledge gained from those links (you posted) and explain to us in simple words so that every one can be enlightened ?

and mr.punarvasu (i hope i got your name/gender right & you dont have to go thru legal hassles now), also please enlighten us as to why the cbr150 has a higher engine oil drain interval in thailand when compared to india ?

I think most em would want to give you redbull instead of water (gives you wings so that you can fly out from this forum/discussion) or like you said earlier.. its better to keep mum (practice what you preach oh almighty)

my recommendations on the engine oils are purely based on the combination of a bit of common sense/experience and availability of oil (grades) in india.
and if you have the time, try to buy 2 test tubes and fill em up with different oil grades/brands and put a small marble in it and try to put em in the refrigerator then heat em (note down the temp of oil at different time intervals) and then invert them and observe the rate at which the marble drops (i am sure you are smart enough to seal the test tube end).. all this bit of home science MAY give you some conclusion.

Redbull? What is it?

Red Bull - Wikipedia, the free encyclopedia (and oh btw the country of origin of redbull is thailand)
and i have edited my previous post to add a bit more of text, if you may want to read it i.e.

In the village I live, we the villagers do not get the modern facilities and luxuries you city people enjoy. Here the news and information reach very late. That is why I asked what RedBull is. Truly speaking, I thought it is another brand of engine oil.
It is not easy to gather marble pieces and test tubes here and appliances like refrigerator are very rare. Yet I shall try my best to conduct the test you mentioned but I think I have read about it somewhere else, earlier.
And I wonder how easily our youngsters are being provoked. Atom family is one of the main reasons. In joint families, people were more tolerating.
