I've said it before, but it's "PEACE of mind". Now that it's out of the way.......quote:

As said, the temps near the bearing will be elevated a little after shutdown, but not extreme as in the old days without water cooling. Leave it run at idle for 30 extra seconds before shut down if you want a little extra piece of mind.
A *little* shearing is not necessarily a bad thing, unless you absolutely need the full rated viscosity.
I'd definitely go with the Delvac 1 year round if it were me in DC. It won't shear down, if that's the big factor. GC by all accounts is great too, but there are posts suggesting that the current production is not the same stuff.
325 . . . guess it's time to tune my R a little.
Isn't there more than just shearing leading to viscosity thinning? What about oxidation leading to viscosity thickening? I thought a good PAO and/or ester based oil resists both.
