they both will work depending on if you have a Manual transmission or an auto trans. the MTL 75w80 is for a manual trans and has additives to protect the brass syncros while the DCTF is used in Automatic transmissions. If you are looking to change the diff fluid u can use redline 75w80 it safe for the spider gears/ LSD but is to slick to use in the MT and dose not have additives to protect the brass. A simple search of redlines product site when entering in your car info will provide all recommended fluids that redline makes
That's what didn't make sense. Redline's site recommended the dctf for my manual transmission.
