I might be reading between the line shere, but it's
worth mentioning that 80w90 gear oil and 20w50 engine oil
are roughly the same viscosity despite the numbers being
very far apart.
Engine oil viscosity is measured at a hotter temperature
than gear oil, which makes the numbers much lower even for
the same thickness of oil.
