So, I just thought it was strange that Redline claims that their MT-90, which is 70-90W, is thicker than their other 75-90W. I went to autoshop, and even though I ditched most of the time, I still think that 75-90s would be all the same as far as thickness (viscosity) is concerned. Anyone know what's up with that? Id think if it was thicker than it would be 80-95W or something.
