Mineral oil product families often include well known branded lines from major oil companies, and ester and silicone fluids have their own recognized trade names.

For safety and compliance, the key is not the brand name but the batch test certificate, SDS, and verified conformance to the specified standard and corrosive sulfur requirements.
