I have reached 1000km on my Yamaha NMAX and I need to change engine oil. It is also recommended that I change my final transmission oil.
As it says on my owners manual:
Engine oil SAE viscosity grades: 10W-40
Final transmission oil type: Motor oil SAE 10W-40 type SG or higher.
I have bought Castrol Power 1 Racing 10W-40 for my engine oil, but is it ok if I use it for final transmission oil also? If no, what product should I buy? Thanks.
