shouldn't it be 40weight at temp? where 0-20 is 20weight at temp? how is 40w thinner?
anyway, my main point is that they're deviating from manufacturer specified thicknesses like none of it matters, and then get a shocked face when the motor blows up...
simply show me that more blown motors have ran 0-20 for oil than trackbro's running something different, and i'll rest my case.
