Yamalube engine oil: which oil for which Yamaha.
Yamaha lists five Yamalube engine oils: four 4M four-stroke oils in 5W-30, 10W-30 (mineral or full synthetic) and 20W-40, and the 2M TC-W3 oil for water-cooled two-strokes. What separates them is which engines each one is for, and Yamaha spells that out: the 20W-40 is for large four-strokes in warm climates and not for V MAX SHO, while the full synthetic covers every gasoline Yamaha four-stroke.
