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.
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.

To check the oil level in the oil tank of a Yamaha PW80, first ensure the bike is on a level surface and the engine is cool. Locate the oil tank, which is typically on the right side of the bike, and look for the oil level window or dipstick. If it has a window, check that the oil is within the marked range; if it has a dipstick, remove it, wipe it clean, reinsert it without screwing it in, and then check the level. Add the appropriate 2-stroke oil if the level is low, ensuring to use the correct type recommended in the owner's manual.

The Yamaha PW80 typically requires a two-stroke engine oil designed for air-cooled engines. It's important to use high-quality oil that meets JASO FC or JASO FD specifications for optimal performance. Always check the owner's manual for specific recommendations to ensure proper lubrication and engine care.
Yamaha's Yamalube, 2 stroke oil is a good choice.

In a stock PW80, there is no need to mix oil with the fuel. The oil is injected into the carburetor throat by the oil pump. The factory ratio is estimated to be about 24:1, which is quite rich. On bikes with the oil pump disabled, ratios as lean as 40:1 have been tried with success. The optimum ratio will ultimately depend on the elevation and the jetting used There is an oil tank under the seat
