It is a type of ........................................................
32:1 to 36:1 but you shouldn't have to mix it. The PW80 comes with a Autolube oil injection system eliminates the need to premix fuel and oil.
All the Yamaha PW80's and PW50's are 2 strokes, so they dont have engine oil. You mix 2 stroke engine oil into the petrol using 25:1 mixing ratio as im pretty sure you know this already. But they do have transmission oil. You can use 4 stroke engine oil for this, or alternatively, use proper transmission oil.

The Yamaha PW80 typically uses a two-stroke oil, which is specifically formulated for air-cooled, two-stroke engines. It's important to use a high-quality, low-smoke oil to ensure proper lubrication and engine performance. Always refer to the owner's manual for specific recommendations regarding the type and ratio of oil to fuel for optimal operation.

Yamahalube 2s (autolube 2 stroke injector oil)
AnswerIf its the 2 stroke oil you want to put in, it needs to be mixed in a petrol can with the petrol, usually to a ratio of 50;1. If its the engine oil it only goes in the clutch housing as it is a wet clutch. If the hole is about half way up the casing, it usually means you keep bike upright and top up until its running back out the hole. Note: Although the above answer will work, the PW80 is an auto-injector bike. The oil tank is located under the seat which is removed with 2 10mm nuts accessed under the rear fender. There is a viewing window on the left side cover to check the oil level. You should use Auto-Injection 2-stroke oil available from a Yamaha dealer.we have one in the family. you have to remove the seat as above but you do not have to mix the petrol and oil yourself
Wet clutch oil. I would recomend using Yamalube.
