My understanding of viscosity quite weak. After using the search button a bit, it's still pretty weak so here's a few questions....
Does a 5W-40 oil for example, actually thicken as it's temperature increases or does it just not thin as much as say a 5w-30 at the same elevated temperature?
Does a straight 30 weight oil maintain it's 50 degree "viscosity" at 200 degrees?
Does a 0w-40 have the same viscosity at 200 degrees as a 15w-40 at the same 200 degrees?
Very much appreciate the help....
