That's exactly what the oil analysis reports stated when used samples of Pennzoil Platinum and Ultra Platinum were submitted for testing.Pennzoil is all GTL and prone to shearing.
The absence of that text on the reports for the other two 5W-30 synthetics I've used in the Jeep, Mobil 1* and Castrol Edge, informed my decision to never have another jug of Pennzoil darken the doorway of my garage.
The foregoing illustrates very plainly the value proposition of a testing service.
*Just the regular Advanced Full Synthetic, not the Extended Performance version. Same with Castrol.
