I'd look around...

I've seen a lot of stuff online discussing motor oils...

Most say that a 0W-XX oil is a 0W oil that has been engineered not to thin more than XX when hot... (and a 15W-XX is a 15W oil that won't thin more than XX...)

I also read about the "spread" being a factor as well... 0W-40 has a 40 spread, while 15W-50 only has 35, and 10W-30 only 20... The theory being that the wider the spread, the more additives and finagling has been put into the oil to make it perform like that. That's that much more stuff in the oil that is in there for a purpose other than lubrication.

I'd love for someone more knowledgable to pick up on what I'm talking about and clarify...
