Don't spill it! You will have that unique smell in your shop/garage for weeks and it permeates everything!

I use only GM posi additive as I have had issues with anything else as far as clutch chatter.

Draining the old, used oil, is the strongest and worst, smell and there is no way to avoid getting that smell in a building, unless it is drained outside. The new oil, almost, smells good, compared to the old "stuff"...

When I had my rear end shop I smelled like that every day for 15 years.
