Just recieved a "new" 95 Explorer with 93k on it, that appears to be pretty clean, and runs well. Would it be okay to use a mix of green and gold in the 4.0L V6? I think I have 3qts green 2qts gold.(don't know for sure though, cause I not at home). It has been run on all dino so this will be the first synthetic it sees, is GC a good choice for this motor? Has anyone used GC in a 4.0L Explorer? Hope you guys can help me out, thanks.
