Re: Yamaha YZF-R15 version 2.0

First of all, there is nothing in the terms of warranty which says that you must use Yamalube. The terms of warranty is a contract document that you will have signed as having read and acknowleged while you have taken delivery of your bike. The said set of terms are now a contract between two parties; you (the buyer of the bike) and the company (the manufacturer of the bike). The written terms of the contract cannot be overridden by word of mouth. Just because the the SVC says that you need to use Yamalube or else your warranty is void does not make it a fact. You should have known your rights and should have fought for them, not taken them for their word. Also remember that the warranty will need to be honored by the company and not the SVC. It has no business telling you what oil you should use as long as the recommended grade and standard of oil that is mentioned in the users manual is used.

Now, coming to your contention that people who have used FS oil have faced problems; what problems? Did their engine seize? Did the cylinder glaze? Did they have overheating problems? Who are these people who are making these claims and what is the basis for blaming the oil used for any of these problems? The contention that mineral oil is good for running in an engine and only after a certain number of kilometers should semi and fully synthetic oil should be used is more that 15 - 20 years old. This contention is no longer valid and does not apply to modern engines. It may be surprising for you to know the reasons for such a contention. It was the superiority of the synthetic oil's film and sheer properties that lead to the contention. Due to this it was contented that engines could not be loaded properly to brake the oil film for effective braking in process. However, a lot has changed in the past 15 - 20 years. Today, Car and Bike makers (including Yamaha, BMW, Aprilia, Benz, Audi) are using semi and fully synthetic oil right from the factory. In fact, I would go so far as to say that with the plated cylinders that now come with the current engine instead of liners, it is better to use semi and fully synthetic oil.

Re: Yamaha YZF-R15 version 2.0

My bad, i did not fight. Thanks for the correction :thumbup:. Also, a fellow xbhpian (dont know from where) was forcefully made to buy a can of Yamalube in his first service when he had not opted for oil change. The SVC had told him the same what i was told about the warranty. All the bikers are not real expert out there. So, they look upto the SVC to advice them, what is good and bad for the bike

Regarding the use of FS oil, many xbhpians have faced leaking issues, clutch slippage when their bike was new. So, i was talking in that sense. Also, i am aware of the fact that, many bikes/cars are factory filled with FS oils.

Cheerz!!

Re: Yamaha YZF-R15 version 2.0

since yamalube is produced by motul specially for certain yamaha motorcycles, and since the yamalube for the R15 is semi-synthetic, and also since yamaha and motul know about what's good for these bikes more than us, i don't know firstly why one would instead go for mineral oil (which is generally a big no no for the R15 and other modern tech bikes) at all and secondly why one would like to switch to fully synthetic oil so soon on a bike whose by-default oil is semi-synthetic...as far as i know and understand, the switch to fully synthetic in R15 should be made only after racking up tons of kms on the odo, probably at least 5000kms or so (so that the engine has got used and "hardened" enough, so to speak, by that time to make oil quality changes if one wishes so); that is, if one really wants to use the fully synthetic at some point...

sticking to the factory recommendations and settings is almost always the best thing, particularly for bikes that are not-so-old (by distance)..particularly when the factory is someone like yamaha, not some manufacturer with hardly any experience in performance motorcycles..they know what they are doing

Re: Yamaha YZF-R15 version 2.0

^^^ as I mentioned in my earlier post; on what basis are these claims of full synthetic oil not to be used till 'x' kms being made? You say it should not be used for 5,000 kms, some else is saying 3,000 kms, another will say 10,000 kms, etc, etc.

So on what facts is your claim based? Do you have anything in writing from the makers of these oils or for that matter from Yamaha saying that these oils cannot be used from inception and should be used only after 'x' number of kms? Can you point anywhere in the user manual or for that matter in the service manual that mentions this restriction.

As for the Motul connection of Yamalube; For India, Yamalube is no longer sourcing its oil from Motul. It sourced locally from a Indian blender. Yamalube is sourced by Yamaha from various oil companies across the world such as oil giants like Exxon, Shell, Caltex, etc.

Re: Yamaha YZF-R15 version 2.0

i am not claiming anything. and no, the manual or the manufacturer or the oil company etc say nothing about it.

however, i was told what i wrote above by the SVC mechanic on the day of the delivery of my bike 20 days ago. while he was prepping the bike and inspecting things and all that, i was talking to him and asked him a few things. one of the things that i asked him after ensuring that he poured the SS yamalube in the bike, is that is it advisable or okay to use a fully synthetic oil in R15 as i have heard a lot of people doing so. he told me that one can do so, but not in an engine that is new and/or not sufficiently used and experienced (hence i said the engine should be sufficiently "hardened" up, so to speak, before changing oil quality), and then i'd asked him roughly how long an engine life he means by that and he said that it's better to do these kind of things after the bike has been run for something like 5000 kms or so..the simple mechanically-experienced reason that he gave me for this, and which makes sense to me because mechanical things are kinda that way, is that a sufficiently used and experienced engine finds it better to adjust to some crucial changes or deviations (such as changing the oil quality/composition for instance) from its factory default recommendations/settings than a relatively new or less used engine..

i took and take his word as he is an experienced guy working everyday on yamaha's motorcycles.

Re: Yamaha YZF-R15 version 2.0

Yeah if you go by their advice, then you gonna be revving your bike straight to 9k on neutral when the engine is cold.

Re: Yamaha YZF-R15 version 2.0


no he didnt advise anything of that sort...

Re: Yamaha YZF-R15 version 2.0

So no oil company 'say nothing about it' eh? Maybe this should make it a little bit more clear:

Q.: Is it true that new engines need break-in periods using conventional motor oil?

Ans: That is a myth. In the past, engine break-in was necessary to remove metal flashing or any other abrasive material left inside the engine after machining, as well as to allow the valves and rings to "seat" properly. Today's engines are built with much tighter tolerances, much improved machining, and under much cleaner conditions compared to the engines of 10 or 20 years ago. Current engine manufacturing technology does not require a break-in period using petroleum-based motor oils.

The above is a direct quote from the Mobil Oil website. You may want to go through the same and quit taking the word of your ill advised SVC guy. Here is the link: http://www.mobiloil.com/USA-English/...AQs.aspx#FAQs4

Re: Yamaha YZF-R15 version 2.0

I agree to this.. Don't believe in break in period for today's advanced bikes

Re: Yamaha YZF-R15 version 2.0

if by conventional motor oil or petroleum based motor oil, you mean mineral oil, well i never said one should use mineral oil, break-in period or otherwise...i rather said not to use it at all on modern bikes that come with semi or fully synthetic oil by default.. so that point in mobil's FAQs is not relevant at the moment, as it talks about conventional motor oil which presumably means mineral oil.

so you'd confidently suggest changing to fully synthetic oil even when the bike (whose factory default is semi synthetic) is quite new?

and obviously most people will just go by what their bikes' manufacturers' authorised mechanics say (they cant be that ill-advised, no?)...and i think to be on the safe side, deviations from the default factory recommendations and settings should anyway be made when the bike has been run long enough, so that the engine is not so new..just to be on the safe side.

Re: Yamaha YZF-R15 version 2.0

^^^ team-bhp is a forum just as this is a forum and not some authority on oils. Mobil Oil is the inventor of fully synthetic oil i.e. Mobil 1. I think as one of world's largest oil and gas company, it qualifies as an authority on oils and knows more about oils than GTO (the writer and moderator of Team-Bhp).

I have simply pointed out the inaccuracies of your previous statement that no oil company says anything about using synthetic oil during braking in or inception. The web page that I have referred to is an FAQ page for Mobil 1 fully synthetic oil, hence the words conventional oils is used.

Why don't you go through the web site throughly before going into a reflex action trying to prove me wrong. Anyway, I have no axe to grind with you.

Re: Yamaha YZF-R15 version 2.0

And may we know why?R15 already has leech like grip on dry roads however i found them a bit weak on wet surfaces.Stick to stock,the monsoon will pass away soon.

Yes.. After riding TVS for 2 years, I can be the best one to say that stock r15 tyres STICK to the road..

Re: Yamaha YZF-R15 version 2.0

For new bikes, its good to change oil soon or @3000kms in our case, but FS oil is good for 5-6ks so its waste of money to put FS early.
This is the only reason i waited till 10k

Re: Yamaha YZF-R15 version 2.0

Abhi
What is your opinion on the GTO

Sorry about the OT
