Do you honestly think you’re correct that the SAE,ILSAC, and all of the major oil manufactures have unknowingly incorrectly labeled oil since the creation of multigrade oil?!? > > You’re wrong and you’re being a troll on your own forum. Why not try to save some face, admit that you’re wrong, and move on? So all of a sudden no more logical argument and you’re attacking me? Perfect, two down, thank you. Thank you for playing. Moving on, now that we all see that the grades are directly comparable, ignoring Travis’s theories and claims based on nothing VS plenty of evidence above clearly displaying that they are. Therefore an oil that is thick should have a high number, and as it gets thinner it goes lower or more viscous. 10w30 should be 50w30 using their own rule “Low # thin, high # thick” 50 when it’s cold and thick, then a 30 once it warms up and thins. --- _[View the full topic](https://forums.speedlife.net/t/oil-how-does-it-work-split/262189)._
