in 2 strokes its called as Gearbox oil, the term engine oil in 2 stroke world is referrec to as 2T oil which is mixed in petrol !

Oh.Thanks bro,I Didnt know that.

Gear box oil, Engine oil, transmission oil, all these refer interchangeably used and they are same.

2T oil is completely different and that goes along with petrol as fuel into the combustion chamber (via autolube or premix). Engine oil does not mean 2T oil in 2stroke world, at least what I know in India.

WRONG! In a 2 stroke motor the 2t oil is actually the engine oil rest everything else is secondary. There is a reason why they call it 2 stroke "engine oil".

Don't believe me? Google for it you should have done that in the first place don't give wrong facts.

Everyone confused me!

ya thank you,i already know but we can say gear box oil also as it is written in yamaha rx135 5s owners manual.then also can anybody suggest me a good engine oil for tvs-suzuki samurai.

buy any oil of api sg grade 20w40, mobil 1 will do the best, if you are not able to find it, then purchase servo 20w40 from any of Bharat Petroleum bunk !

DAFC, I laud your knowledge, the question I answered on the 2T oil is all about and the difference. What they call it in your state is secondary to me. So fact is that you'll need to go down to street guy and ask a question whether one knows what comes up while googling 2T oil!

There is only two oils known for 2stroke in India. 2T oil and gearbox oil. Period. If you still want to argue, please go ahead. If there is a 'like' button as in FB would definitely check that for you!

@Aneesh: 2T oil is widely known to petrol bunk guy and even a street guy and that makes it very clear. Engine oil term might be technically right as dafc says you'll its upto an individual when it has to be communicated.

You need to start paying attention and quit typing with one hand, I never said what they call 2t oil up here or down there at your side nor did the guy ask anybody how to approach a petrol bunk guy or some shanty ol' lubricant owner for 2t oil? You said 2t oil is not engine oil have you ever read the stuff written on a 2t oil bottle carefully? I hope you don't forgo the 2t oil part either and pour in 20w40 oil instead oh lawdy lawdy oh

@rxboy 2t oil is engine oil in 2 bangers, the stuff that goes around in the transmission, the stuff that's poured in on the right near the kick lever, is not 2t oil and don't ever try to substitute that for 2t oil or vice versa.

ps: Sriram lighten up a little you're always uptight and that'll get you nowhere

I did not know what is 20w40 and you have opened my eyes and also I'm not going to go anywhere as I've been around. I love you dafc!

LOL no worries

+100 to what you said...

In Two stroke's world Gear Oil is the one which is filled near to the kicker. Engine oil is the 2T oil pumped by the Oil pump or mixed with the petrol

Hope this link will help

Two-stroke oil - Wikipedia, the free encyclopedia

Motor oil, or engine oil, is an oil used for lubrication of various internal combustion engines. While the main function is to lubricate moving parts, motor oil also cleans, inhibits corrosion, improves sealing and cools the engine by carrying heat away from the moving parts.

Other non-motor oils include gear or transmission, and differentials oils. These are used in manual gearboxes and driven axles. They could include specialty uses including EP (Extreme Pressure), hypoid, and limited slip functions.
Again, they are not to be used for engine lubrication. (from yahoo answers)

sanjith,

you are wrong...

In general atleast any where in india. for bikes 2 stroke or 4 stroke..

engine oil means the lubrication oil which circulates inside engine crank case for lubricating/cooling moving engine parts like transmission gears, clutchplates, shifters,bearings etc.. which will (should) not burn inside combustion chamber.

2T oil or side oil(because 2t oil tank will be on the side of the bike) refers to auto lube oil which will lubricates the moving piston,rings,piston pin,along with cylinder and burns inside the combustion chamber along with air fuel mixture.

for Thumpers old model Bullets(cast iron engine) gear oil is diffrent from engine oil since gear box is not inbuild inside the crank case like bike engines. so gear oil will be filled seperately with different grade oil for lubricating transmission gears.

for 2 wheelers in general widely we use only two terms

Engine oil or 2t /side oil.


transmission oil, gear oil terms are only used for 4 wheelers where trasmission will be seperate like gear box, diffrential drive axel.

Hope this would clear..

Edit: if one consider only cylinder,piston, connecting rod and crankshaft alone as engine in two sroke bike... then he can surely call 2t oil as engine oil.

Correct.

Here is a brief summary in 2-strokes:

1. 2T Oil - Used for Lubrication & is a part of combustion process. Items covered: Crank Shaft, Cylinder, Piston, Head.
2. GB Oil - Used for Lubrication only. Items covered : Gearbox, Clutch Assembly.

Sriram has pointed out in utmost simplest way, so that even a layman can understand it. Sorry, but i have never heard of Engine Oil being referred in case of 2-strokes in India. I have no idea what terminology they use in US or UK!!! I am talking about India in general (N-E-W-S).

Yes, you are correct. Since engine oil is not burning inside the combustion chamber, we can't call a 2T oil as Engine Oil. Correct me if i am wrong.


+ 100000


We can never leave out the Gearbox & Clutch assembly. They are very much responsible in an overall engine as the above mentioned items for the engine to perform at its peak.

Check this one dear friends

Hope this is going to give you all a clear view about 2T Oil(Engine Oil) and Gear Oil..



'YAMALUBE' Gear Oil can, See the term used there its 'GEAR OIL'
See the below scan too.
