How fast do oils shear back?

[GoldenRod]

For Example: Chevron Supreme 10W-30 spec'd 10.8 cSt @ 100C. What would be the viscosity of this oil be after 1500 miles assuming there was no fuel dilution?

search for your conditions in the UOA section

eljefino, Do you think I'm an idiot? I just came from the UOA section, which is the reason I started this thread. It seems as though a lot of oils start out at a certain viscosity, and then shear back to a grade below at 1500 miles. Here's an example here: http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=3;t=003414;p=1#000005
