Some quotes:
Quote:
Mr. Kabel [Castrol] stated that motor oil manufacturers, including Mobil, regularly make changes in their formulations, both base stocks and additives, without disclosing these changes to consumers, regardless of whether the changes result in an increase or decrease in performance. Mr. Kabel stated that in the case of Syntec, there was no need for Castrol to notify consumers of a change in formulation because the overall integrity of the product remained the same.
Quote:
The challenger [Mobil] asserted that it tested (and had an independent laboratory, Savant, Inc., separately test) samples of the current and former versions of Syntec. Mobil provided test results showing that the current version contains no PAO and either no or only a trace amount of ester, while the former version of Syntec contains 70% PAO and 7% ester.

Will history repeat itself? A little ester now in Magnatec, a quiet little reformulation later?
