Found a 10 years old leather conditioner, Connolly Hide Care Conditioner, in my garage. Back those days, it was selling for $12.95 at Lexus dealership. Almost a full can, however, the ingredient has been seperated during the storage. Can I still use it?
The usual usable shelf life for a leather conditioner is three (3) years providing they have not been subjected to extremes of temperatures (i.e. 32oF< or > 95oF
I don't know if this will help your decision or make it easier but Connolly Hide Food / Care is formulated for un-coated leather (Jag, MB Premium Leather, Aston Martin, and etc)it is not compatible with covered leather, I'm told (but have no first hand knowledge) that it will adversely effect the urethane covering
