Now I understand. It would be interesting to see different oil's specs at all those different temps. It would give us all a better idea of how the oil will operate in our own individual climates.quote:

I'm talking about the oil's viscosity at different temps, not the engine's temps. Sure, the 40C and 100C visc is given on spec sheets, but I'd like to see what they are at say 0C, 10C, 20C, etc.
Exactly. Personally, I don't care about anything below 0C as it very rarely gets that cold here and my cars are garaged both at home and at work.quote:

It has both. The web site is dead right now, but the xw30 @ 100C oils are around 10.0 +/- .3 if my memory serves.quote:

Is it because it is stable?
From what I recall the SuperSyn 10w30 has a cst of 9.8 at 100c, 5w30 is 9.7. The TriSynthetic was at 10.0 for both.quote:

9.3 to less than 12.5 cStquote:

What is the low end and the high end numbers for a 30 wt?
