Kees,

I don't quite understand this statement.  A different viscosity rating 
means, well, the oils have a different viscosity:

"Kinematic viscosity is graded by measuring the time it takes for a 
standard amount of oil to flow through a standard orifice, at standard 
temperatures. The longer it takes, the higher the viscosity and thus 
higher SAE code." -- Wikipedia

According to Redline, MT-90 is equivalent to 75W-90 gear oil or 15W-40 
motor oil--not 20W-50 as I recalled incorrectly--and MTL is equivalent 
to 70W-80 gear oil or 5W-30 motor oil. 

The differences may not be noticeable in the bottle, but they are 
measurable.
