You can’t compare them to each other when on the same bottle (which you’re trying to do), but you can compare the non W number and the W number on the same bottle to the SAE scale-

Again, for the 10000th time, 5w30 oil flows like a SAE 5 at low temps (hence the w), and like a SAE 30 at high temps (hence leaving off of the w).

If you cannot grasp this concept soon, I’m going to start to question your ability to run this forum. This is honestly one of the silliest arguments that I’ve seen in the history of the Internet.
