Why does Havoline smell the way it does?

I have a big stash of 5L jugs of GTX with a case of single quarts of havoline to top of the oil when I change it.You open up the Castrol and it smells like..well...what oil should smell like I guess, but the havoline really has a pungent odor to it. What gives? The add pack maybe!? Is it normal?
I have to qualify this-I normally don't sniff oil. However, since they are 2 different products with 2 different additive packages I would expect them to smell differently.
Somebody's spent too much time on a pig farm... (We've got 'em near where I live. When the wind shifts, the odor takes your breath away.) I've noticed a "stronger" odor with the TropArtic 10W-30, too. GC "gold" ain't no bed of roses, either. Wouldn't it be a hoot if the mark of a quality motor oil is related to how much it stinks?

I was going to say fatback but pork rinds are close enough.
