G'day Mate, the Valvoline SynPower 0W40 is very common in Australia, but I hear less so in North America.
In NA I would probably go for M1 0W40 or Castrol Edge 0W40.
Having said all that, I too find Castrol Magnatec very smooth, as you do.
Have you tried running higher octane petrol (gas), it's quick and easy to try, and it may just fix your issues. It may be a bit of pre-ignition when the CVT is caught between two gear choices at a particular RPM & MPH combo. This can happen if the engine ignition advance doesn't quite work with the RPM selected by the gear box (too high gear). A slight increase in fuel octane should fix this miss-match easy.
