Marathon Multi-Purpose DM ATF
General Motors and Ford Motor Company has set forth a number of laboratory and rig tests required to meet the former Dexron III and Mercon performance specifications. Although laboratory tests alone cannot be used to establish if an ATF meets these specifications, they can be used to determine if it doesn't.

The following is a comparison of the test results for the sample of Marathon Multi-Purpose DM ATF tested with the Dexron III/Mercon requirements.
