Engine/transmission oil question

[orange71]

Is SAE 30 the same oil whatever you use it for? I need some transmission oil for my moped and it states SAE 30 engine oil or GL gear oil - if I find SAE30 can I buy anything whether it's for lawnmowers/4 strokes/2 strokes/cars whatever??

cheers

I would say yes, but read this to be sure http://en.wikipedia.org/wiki/Motor_oil

2-stroke and 4-stroke oil is different I believe. ..

I'd buy some dedicated stuff from a motorbike shop to be on the safe side. Make sure it is specifically gear oil, not sump (engine) oil as they may be formualted different and have different properties:

If the gear oil requirement is 'SAE 30 Engine Oil' then it needs engine oil surely???

The original post specified it was 'transmission oil' that was needed, hence gear oil was my reccomendation. I am assuming it is a two-stroke bike with a auto / semi-auto gearbox.

If ever in doubt check the API number, this will indicate the composition of the oil better than the SAE number. Foaming agents etc all affect the behaviour of oil.

Thanks - this is the wording in the manual:

Transmission oil: SE engine oil type SAE 30 or GL gear oil

Leaves me slightly baffled! Was just looking to get cheapest 500 ml off ebay. I only need 110ml.

Gear oil has different properties to engine oil.
Buy the proper gearbox oil, I would recommend Silkolene or Rock oil in the appropriate weight.
Standard engine oil will go very thin very quickly as it gets smashed about by the gears.
