I'm getting ready to do a drain/fill on my 2012. In the process, I found an unopened quart of DW1 from when I serviced my prior 2001 years ago. That quart, left on the shelf in the garage, is probably 5 to 6 years old. Is it ok to use?

Based on similar questions about automotive fluids on BobIsTheOilGuy, I'd say it is OK to use.

Suggest shaking the bottle first, in case any additives have settled.
