US versions are not lower quality. Branding has nothing to do with quality. It is strictly about marketing. If a lubricant meets standards, it should work fine. It is just that there are better deals. and sometimes better lubricants, for most applications. As an example, the Shell Synthetic Helix Ultra oil is rebranded in the US as Quaker State Q. Same stuff, different container. One is $20/liter, and the other is $8/qt. I have tried both the Shell and the Quaker State Q and both foamed too much for me and my techs, so we switched to Valvoline, which does not foam and has done well in comparison tests.
Similarly, Shell Donax UB brake fluid tends to leave a gummy residue, so we switched to Castrol LMA, which bubbled too much, and then to ATE Blue, which works great.
You and your techs have to review what goes into your car and make sure it is not causing problems.
If you look at Bradan's service and restoration threads, they swear by Redline lubricants. I swear by Valvoline. As long as you are making educated choices, you will be fine. If an FNA dealer is doing the servicing, you will get Shell products.
Like Stef says, if you change fluids regularly, you will not have problems as long as your lubricant/fluid meets specs and standards.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
