Oil... how does it work? [split]

You’re kidding me right?

Vlad, thanks for the entertainment! But enough is enough. Here is your answer…ready? Sitting down?

Ok.

The number with the “W” after it is tested at 32 degrees F, and the number without the “W” is tested at 210 degrees F.

Thanks for playing,
Travis

@Vovchandr

First number on the bottle is at freezing temp IE “5”, second number on the bottle at operating temp, IE “30”.

@Vovchandr

The first number on the oil bottle is viscosity measured at 32 deg F, and it’s easy flowing, while second number means it’s thicker or less flowing.

You just literally repeated what I’ve been saying. Just about word for word, even the same article.
