722.6's are still being used in some cars. The fill in the factory is the latest 236.14.

236.14 is backwards compatible to the 722.6. Old 722.6 fluids are not forward compatible with the newer 722.9.

722.6 fluids and filters must be changed every 40,000 miles or 60,000 kilometers

If you go to a dealership and ask them for 722.6 fluid they will supply 236.14
