John - The Redline MTL is great for transmissions, but NOT for the differential portion of the transaxle which exists in the DeLorean application. The MTL just doesn't have the shear stability for diff use. I would personally recommend using a good synthetic gear oil that meets GL-5 specifications. I believe the MT-90 nearly fits that criteria, as do several other products from Castrol and Amsoil. According to the Redline website, the MTL (which is rated to GL-4) should not be used where GL-5 is specified, but MT-90 comes closer, even though it is also rated to GL-4. They say that 75W90NS is the Redline product to use for our GL-5 application. I use a Castrol synthetic gear oil in Winged1.
