The fact that TGMO 0W-20 is a 0W oil is incidental as it is not targeted at extreme cold performance but rather being as light as possible at more normal start-up temperatures.
In that regard I'm sure it contains no pour point suppressants.
It's the same with many 0W oils including M1 R 0W-30 and 0W-50. Do you think Mobil formulated their racing oils to perform at -40 degrees? Of course not. It's simply a consiquence of using high VI light base stock oils. Technically speaking if an oil meets the minimum 0W pumping spec's the formulator is supposed to label the oil as such.
I'm a little confused here. Edge with Titanium has a PP of -38°F, you mentioned below -40°F? or is it -40C? Either way Castrol Edge calls it a 0W20 oil, having the same PP as their 5W20. Thanks, I'm still confused by this, and Castrol's lousy PDS.
Boy did they destroy that oil with the move to API SM. JMO
-40F is the same as-40C.
Thanks, but their PDS says Pour Point, ºF (ºC) max -38(-39) -38(-39) , does that qualify it to be a 0W20 is what I'm wondering? It is also exactly the same as their 5W20.
I'm not splitting hairs I'm trying to learn, I thought the cut off was -40F. I also didn't realize -40F and -40C were the same.
