It's not in conflict with what OJ888 said. The manual specifies operating ranges according to ambient temp, but the second rating is indeed for viscosity at 100°C:Originally Posted by kisshmet
The manual states atmospheric temperature not the engine temperature
Be careful changing oil while the engine is hot..dripping hot oil could scald you

Even if you look at SAE tables the second measurement is 100°C/212°F:Viscosity is notated using the common classification “XW-XX”. The number preceding the “W” (winter) rates the oil’s flow (viscosity) at zero degrees Fahrenheit (-17.8 degrees Celsius). The lower the number, the less the oil thickens in cold weather.
