Engine Oils

[FranklySpeaking]

lol @ hair dryers
these hair dryers are more than sufficient on Indian roads: )

well regarding changing the kit, why changing when something is not broken ?

A set of cylinder and piston can go on only to an extent and it just cannot go on infinitely long period. Motorcycle was drinking oil, so I opted to change the kit rather than going for rebore and one size oversize.

hmm.. thats great.. can u tell me the price of yamalube 20w40/?? ...

Yamalube 20w40 SL mineral was 270.00 when I last got it (about 8 mnths back) . Yamalube 20w40 mineral is/was also available in a SG variant , as good and was cheaper . You have to buy it from YASS parts counter , no discounts , no bargaining ... but that means it's guaranteed genuine too .
Motul/Gulf/Valvoline 20w40 mineral oils are also labeled around 270.00 Rs now , but they have some discount coupons on the bottle(or inside it,floating in the oil) .. plus bargaining at the shop - comes around 200-230 Rs now .
You can go either route , depending on availability and convenience ... it is difficult to find a too bad 20w40 motorcycle mineral oil in our markets .

I have been using 20W40 in my splendor+.
I am looking for a good 10W30 oil(SS/FS).
How is Gulf pride 4T synth 10W30 ? ...

After the summer heat subsides , try out a bottle of Gulf synth 10w30 ... I have a premonition that it's going to be an fantastic oil . It's not much more than Motul 3000 either ....

.. Before you jump the gun, you should realize that not everyone rides these 100-150 cc hair driers on wheels...

Nice one , don't expect any sympathy from me when you are pushing that one with a flat .
What are you using in the clutch and gearbox ?

nice question there.. Cars are fitted with catalytic convertors and bike oil contain a lot of zddp.. These kill the catalytic converters.. If you have a very old car which was using below API SG oils.. Nothing happens.

But one should use car oils in cars as these have friction reducers which improve a car's economy and reduces emmisions. Also, bike oils are costlier than a car oil.. 5 litres of a car's mineral oil will cost you less than 1200. But if you buy 5 cans of corresponding bike oil, you will spend 1300 bucks. Though a marginal price difference, but it is there(though it can just be packing and handling charges).

err two wheelers don't have catalytic converters?
as far as i know i read somewhere that my vespa lx125 has a catalytic converter.
sorry if i am sounding too noob but this is my first 4 stroker!

but bikes also have cat cons, right? Another thing our 2001 alto also got cat con and minimum rated oil should be SF/SG/SH
i'm kind of confused.

Gulf Pentatec 10W30 for clutch

Servo EP140 gear oil for gearbox.

@PSR sir,Pinaki ji and muztariqji :Can i use Honda Throttle 10w30 FS in my RTR 180, as it is affordable as compared to other FS oils.
I have read that using synthetic can lead to clutch slippage in RTR

TOP up

Hello, i went to top up the engine oil today for my zmr.....the showroom gave me 4t plus (Meets API SJ Jaso MA specs-10W30 SJ) engine oil.....is it the same as HH4t plus (SAE 10W30SJ GRADE Jasoma)???

Please let me know...

well, I'm not the guy you want answers from but I'd say stay away from w30 oils. Use w40. Unless temperatures are below 30'C.
And about the question of affordability, gulf has 10w30 FS (pinaki ji's using it now I guess) which costs less than Rs350. And I've heard Valvoline is coming up with 10w30 & 10w40 FS oils with similar pricing.

[FranklySpeaking]

well, I'm not the guy you want answers from but I'd say stay away from w30 oils. Use w40. Unless temperatures are below 30'C.

Ambient temperature of less or more than 30 degree celcius has nothing (almost) to do with the number after the W since that number-30 after W has to do with its viscosity-equivalent at 100 degree celcius!

Temperature that the oil might get exposed to inside a petrol engine can go as as high as 150-160 degree celcius!


When one talks about the number before W (winter), one talks about the ambient temperature and when one talks about the number after W, it is then when one has to talk about the temperatures that oil might have to face (something of the order of 100-150 degree celcius)

i'm kind of confused.

yes, many bikes are fitted with cat.con including mine.. But it is quite a scaled down version of a modern car cat.con.
Just tell me which euro 1,2,3 etc or bharat stage 1,2,3,4 emmision norms does these follow..
Motorcycles, especially four stroke ones run quite clean.. They burn quite less fuel, so our pollution control bodies are not implementing these emission norms on bikes.. Even tho the number of bikes are much higher. Once strict emmission norms are in place, we will lose our benefit of using these high zddp containing oils.. The question arises, how come diesel engine oils contain high values of this ingredient - i think their emmission standards are different are relaxed. But if strict regulations come up for bikes.. The cost of bikes would increase drastically.. Installation of FIs, ECUs, High end Cat.Cons many other exhaust system detoxifiers would be a big task, involving a lot of money and technology.
Our govt is a copycat.. Once the world starts following them, we will too.. Even tho the number of bikes in India is much higher than the western nations.

@sanjay 8214 - you can top up with that oil without any risks.. Even if they are different. Relax.

@frankly speaking - i dont think engine temp rises that high in a 100-150 cc (hair driers as per you, if you are talking of your truck, may be after a high rpm run you may get 150deg) if a bike is capable of attaining 150 deg celcius, if ridden normally, engine manufacturer should put up a temp sensor on it.. As its very dangerous to continue riding at that temp and the engine may seize.

Bajaj CT100

can i use Shell Helix 5x40 Full synthetic in my Bajaj CT 100 ?
i am worried as it looks like its for a CAR and not motor bike ?

can someone advise ?

not at all... Use shell advance ultra or ax7 instead.. Using an fs on a 100 cc is waste.. I think you have got some leftover of this oil.. Use it later whenever you want.. Two three years on shelf wont degrade this oil.

@krish - i dont own a rtr, but i think it works on 20w40 grade as per manual.. Have seen ppl using motul 300v 15w50 on it and appreciating its reduction on vibration levels and increasing smoothness.
Buying a 10w30 synthetic just coz its cheaper may harm your engine if the recommendation is something else.
Also, please do not put questions exclusively for some members as it reduces your chances of getting an answere from members who knows about your query. For exclusive queries, private message option is always open.

Found shell ax7 oil ss for 300rs per litre. Sounds like a very good deal for my 100 cc splendor.

Facts are right but the truth is partial. ambient temps must be considered while choosing oils because lower temps will help engine to shed more heat. hence lower viscosity can be used because it wont thin out much. On the other hand, higher ambient temps will make an engine to radiate less heat, this excess heat will stay in engine (and its components including oil) hence thinning its engine oil more when compared to lower ambient temperature.
Another thing to consider is hot spots.
P.S. RTR's recommendation is w40.

yes, many bikes are fitted with cat.con including mine.. But it is quite a scaled down version of a modern car cat.con.
Just tell me which euro 1,2,3 etc or bharat stage 1,2,3,4 emmision norms does these follow..

Car is Bharat 2 and Bike is Euro 3.

Motorcycles, especially four stroke ones run quite clean.. They burn quite less fuel, so our pollution control bodies are not implementing these emission norms on bikes.. Even tho the number of bikes are much higher. Once strict emmission norms are in place, we will lose our benefit of using these high zddp containing oils..

Tunning for clean emissions has always been bad news for petrolheads
And govt. has been lining useless policies for e.g. cars less than 4 meters and engine displacement upto 1.2L.. Now consider the Indica petrol 1.2L & compare it with Indica petrol 1.4L.. 1.4 is better performer than 1.2 and it also is more fuel efficient. now how the hell 1.2 is helping in any case??
another e.g. is of similar cars following Bharat 2, 3 & 4 emission stage. Bharat 2 stage car has more torque in lower rpms than bharat 4 stage
P.S. have always felt cars have more effective cat cons than bikes as have seen (dry) carbon deposits in exhaust of my bike when it was around 10k on odo, but our car exhaust has non even after 91k!![/QUOTE]

yes, yes we need temp gauges
P.S. 100'C is optimal operating temp for engine oils that's why hot viscousity test is done at this temp (and also because 100'C is waters boiling point, so that all the condensation can boil off)
And 150'C is the point where molecules of most mineral oils starts breaking..
