Welcome Ravi
Lol In fact my native is also chennai bro...

That's probably the sweet spot in the range for the grunt and loose visor nuts add to the vibrations....fit them properly....
its the Castrol oil.....change it....also allow the new oil to get settled...it takes 100km for that....then you will be back with the smooth engine....also be careful not to rev hard....

What the mechanic said is not true and it is not related to the engine oil you use.





The recommended oil change interval is 4000 kms in our bike but most of us are changing it in 2000-2500 kms. In any circumstance, you can go up to 2000 kms.

Perhaps this roughness may be your feeling. Or even the loose chain can cause it. Better consult the engineer in the service centre, it the roughness is real.



Both are from the same place, then.

But there are some very knowledgeable persons from Chennai in these threads, though they are not active nowadays here.

Petrol price -

Here is a good news for all of us: petrol price has hiked by Rs.3.14 which in effect is about Rs. 3.50. At the same time, the price of the aviation spirit which is essential for the commoner’s daily journey is about Rs. 45/- per litre in our country.

svc castrol review....

all gspians,please furnish your review about the svc castrol oil..like up to how many kms the engine wil be smooth...did any body used the oil till 2000km....

If you think it is necessary to change the oil and its brand now, do it at the earliest. But the truth is that almost all the oils are the same; the same base oil with the same additives in the same minimum proportion which gives maximum profit to the manufacturer.

None of these multinational companies are working for the benefit of the public. They are trying to exploit us as much as they can.

SVC Castrol Oil - My view threre are three posible types

See my dear friend,

All SVC aren't work by the same way but they have more similarities as recommended by Suzuki.

Due to several complaints from customers, suzuki started supplying oil to dealers with suzuki name on the one ltr or what ever the size can.

But all dealers aren't using the oil, because suzuki never recommends any brand oil including their own branded (OEM castrol) oil.

Let's come to your point the review of the so called SVC / company oil.

#1 initial pack oil: this is the one that comes loaded in the new bike. In my experience and most others felt this oil is on par with the best oil in the market for the run in period, almost many of us changed it at 250 to 1000 kms because of the first service and run-in period.
Lastly the preloaded initial oil is also castrol (you can call this as company loaded castrol oil)

#2 suzuki branded castrol OEM packed oil:

This is same as the castrol red color container (20W-40) oil available at market. Those who tried motul, gulf, valvoline, elf won't get satisfied with this one because this as well as the company preloaded one aren't too smart to cop up with the latest modern engines as castrol haven't met jaso ma2; look at the castrol carton box or can they cleverly mentioned and played with words so as customer won't understand it clearly (they mentioned something like " this oil exceeds jaso ma2 standard" means it doesn't met jaso ma2 standard )

Example :

Customer : give me butter
Castrol. : we offer both butter and milk togather we call it as butter milk which is better and more refined than butter.
Customer : can I make ghee out of it

# 3 bulk castrol oil (this comes in a metal big sized container which holds 200 or 300 ltr castrol oil)

Most SVC preferred this one as its cheap, it is stored in the svc store where you used to go and buy spares and pay bills, as it comes in a big container they might opened the container week(s) back and it might got air contamination.

SVC engineer asks the store person to replace oil on your bike, store guy will load this oil in a measuring jar ( which they never wash or keep it clean) and svc engineer will load it on your bike, this is what most common practice in most SVC and its not only suzuki applicable to all other brands too.

This oil is uncomparably bad as it is already air contaminated, and you will certainly and immediately find the difference in performance if you previously used some good oil and felt the superb performance earlier.

Am I confusing you a lot!!!

Ok let me tell you in simple term

With in run in period just use the castrol oil till 1000 kms after which you can try motul and etc.... Oils

After crossing run in at least till 6000 or 7000 kms on odo just stick to mineral oil, even after that I recommend mineral oil only, but after 10000 kms its the safer enough to try synthetic, but cost wise and performance at common man road / driving environment mineral is the best.

I beg to differ with your theory. While I agree that all companies are looking for profits, there are differences between the engine oil available in the market. For example, when using castrol power 1, I was encountering engine harshness after 700 to 1000 kms. This does not have to do any other issues of the bike. When there is harshness, you just know it as a rider and it can not be defined or explained. On the other hand with gulf pride 4t, shell advance etc. I dont feel the harshness untill after 2000 kms. However, I make it a point to change the oil before 2500 kms. According to well informed people castrol is more prone to duplication as opposed to gulf or shell as it is a popular brand and therefore people has issues with it after few hundread kms. My advice to new owners, stick to gulf, shell or motul (i have not used it. But people using it, swear by it). Raj.

You don't need to beg because what you said is true and that's the fact.

To know the diffrence physically try this.

Take 5 ml castrol oil, motul oil, gulf oil and valvoline oil.

The colour of gulf oil is diffrent from all the other three brands.

In the same way the colour of valvoline is diffrent from the other three brands.

The thickness aka density of each oil is diffrent,

Both the castrol and motul are colorless but you will find a file light yellow shade on motul, if not atleast check touch and the feel it both are diffrent..

Yes am asking you to take oil from new bottle and check it.

The above is just a simple test.

There are more ways to test it and some are risky such as you can heat the oil and check it on how the viscosity ? how the oil reacts ? and how the oil behaves at high temperature ?.

Try and let all know......but don't lie.

From 2000 onwards, Castrol mineral oil in jars were available with the bike dealers; at least with TVS-Suzuki dealers. I am sure about it.


I cannot understand what you mean by ‘preloaded’ oil. As far as I know, no oil is filled in the bike at the manufacturing company. I am not sure about the super bikes, but it is true about the ordinary bikes, up to and including 220 cc.

What benefits, according to you, are bringing this JASO MA2 specification oil to the engine or gear box? In a layman’s words, it minimizes the content of phosphorous - an excellent anti-wear additive in the oil - to protect the catalytic converter in the bike. It protects the catalytic converter but lessens the protection of the engine while it starts. Nothing more; nothing less.

How are you sure that they are cheating the costomers? This is what I have heard about it: “Note that these labels (the same label you see on Castrol jars) list only the API and JASO standards in text form without the proper labels. This means the manufacturers claim their product meets or exceeds both standards, but haven't paid the fee for licensing (and testing). Note that the process to carry the official labels is very expensive, so some oil manufacturers may choose not to obtain licensing, even though their products may pass the tests”. (These words are not mine).

And please know that oils with JASO MA2 specifications which reduces the phosphorous content which is for engine protection is not compulsory here in our India. It is nothing more than a choice. The bike companies are recommending it to protect the catalytic converter and thus the environment. Here we are looking for FFE which have no catalytic converter.

But this doesn’t mean that Castrol oils are not manufactured as per JASO MA2 specifications.


Both are funny; the Castrol and the customer.

I don’t know what the dealers in that big city of yours are doing but here, where we use local slangs, the oil is supplied in jars. No dealer is allowed to buy the oil from the local market. It is supplied directly by the oil manufacturer as per the directions and norms of Suzuki.

Can you please let me know the name of that Suzuki dealer who uses oil filled in metal containers?


What is this air contamination?


Now you are really confusing others. Firstly you said that synthetic oil is safer after 10,000 kms and at the same moment you says that cost wise and performance (wise), mineral oil is best for a common man who drives in common man’ style. Which JASO MA2 oil is the best for our bike?

I have never said that Castrol Power 1 Semi-synthetic is the best oil in our market. But it is true that I have used it for more than 1,00,000 (one lakh) kms in my Suzuki Fiero and that bike which has covered more than 1.3 lakh kms is still perfectly perfect with a virgin engine and gear box.

Now I am using the same oil in my GS after its running in period. It has clocked 18360 kms now and is trouble free.

To avoid the duplicate, I am buying it from an authorized dealer. There may be other better oils like Amsoil but it is not available here in my village.

And about your last sentence in brackets: I too am doing the same from my own experience and it is a bit difficult to change the brand unless I find out a better one.

Yet very reliable and no other viscosity test is needed!



Have you ever tested any oil in this manner?

basumataryraj, please test the oils accordingly whenever you are free and tell the truth .

castrol scv oil reviews

@all, thanks for the responses......guyz please do not beat around the bush....i kindly requested 2 querys at the most (1)is up to how many kms your gs engine runs smooth on svc castrol oil (2)have you extended it to 2000 km in spite of harsh engine behavior to 2000km?

@Raj...thank you for the response.....


@vishnu.....the roughness is not my feeling/theory,this is what i have experienced on my bike.....i have experienced the same before also,but this time want to take our fellow gspians feed back about the same...

I have never used the oil from service center, so I cant comment. But let me tell you one thing, if you are encountering harshness and know that it is not because of any other attributes of the bike, change the oil. Use a good oil, my preference would be gulf, shell or motul. Use whichever you can get. If service guys creates an issue tell them that the oil you are carrying is of the same grade and it will not void the warranty. If they dont listen talk to someone responsible like a manager. Thanks. Raj

* the 10000 kms I mentioned was about after crossing 10,000 kms on ODO.

It is very much safer to switch to synthetic.

In other words if someone wants more smoothness and wow performance at high speed, and for those who wants better acceleration (please read acceleration as want to reach high speed quicker) and better engine protection at higher(stress) temp due to high speed racing.

Synthetic is special oil made for the racing and can be used for the above said purpose.

But for daily commuting even if you use synthetic it needs to be changed with in 2500 due to the stress the bike undergoes in city environment. That is the reason I said mineral (rupees 220 ) and synthetic (above 750 rupees) will survive only for the same 2500 kms, so 220 rupees oil is safer bet.

*******************************
Earlier you said all oils are same now the pictures posted by you proves two varients of castrol make is diffrent.

The reason why I told about heating small quantity of oil is to simmulate the hot environment (like while engine is running) to see the viscosity, and other charerstics of the oil.

Why I said that wierd way ?

Because people like raj or mach50 belives the oils quality by the performance so they don't need to do this wierd way of testing oil, but for those who deeply belives all oils are same then they need to do such kind of test ( I am not sure they may believe it or not ).

No I haven't tested in this manner, but have seen it while during oil change.

When we remove the old oil, the mechanic used to remove the old oil from bike while engine is still Hot, at that time I am able to see and did checked how the oil is.

and this is the result in my testing

Gulf: after crossing 2000 kms got more thicker and still the color is not changed (this is the one kind of oil where as the colour of oil remains same lifelong.

Motul: aftercrossing 2000 kms or even 2500 kms it looks better than any other oil, one of my friend keep on topping it up instead of changing, now his pulsar is 15000 kms old with the motul oil and he said its still silky smooth.

Elf I changed it at 2000 kms. After crossing 1500 kms with this oil I felt oil needs to be changed, came out looks like it blood but not in colour but thickness.

Castrol: my bike didn't rev happy after using power 1 SS oil for 750 kms, when I take it out it doesn't looks oilish but looks like the paint thinner. Even the sticky feel is not at all there.



Regarding the SVC using container oil its almost everywhere. In the past 8 months I visited 3 svc centers in bangalore where I seen it in all those three places.its not only me their are many Gspians reported this long back.

The container looks like the ration shop kerosine continer with dispenser

The svc engineer always brings the oil in measuring jar that jar aka jug is not cleaned.
If they use the suzuki provided 1 ltr or the specfic quantity engine oil then their is no need for the jar as it can be poured directly to the bike.

+++++++++++++++++++++++++
Regarding air contamination in engine oil, instead of me telling just google it to find the fact. Esspecially refer the castrol sugestions on that.
