Use golden circle corn oil lah ... ahahah ... just joking
....
For your question .... what oil are you going to change ? 4T or 2T
? If you are changing 4T, I bet you already know that the oil is
topped up at your engine gearbox case. If you are changing your 2T,
you pour it into s small plastic tank found under your seat. If you
have that plastic tank there, you pour it there. There is a 2T pump
to pump the correct amount of 2T oil into your fuel. Normally, you
dun pur 2T into your fuel tank. If you do, I think you are going to
get lots of oily smoke at your exhaust. Dun pour into your fuel
tank, ok ?
Now, if I am not wrong, 4T lubricates your gears in the gearbox.
The 2T oil lubricates the piston in the cylinder of your engine, so
that the piston does not get stuck in it. When the 2T is sprayed
into the piston area for lubrication, naturally, it gets mixed with
the fuel. There is a proportion ratio of 2T to be mixed with the
fuel. That's why you have a 2T pump. The pump will meter the
correct of 2T into the engine system. If you spray too much 2T, you
get a lot of white smoke at your exhaust.
I am using Castrol GPS for 4T and Castrol Sportec for 2T. If your
bike is new, most advisable to use fully synthetic as it gives
maximum protection.
Good luck !
