I'm new here and I have a question. I have a 94 Volvo 850 N/A 5 spd and I am trying to figure out what fluid I need to use. From reading on the Volvo forums, there seems to be lots of conflicting info on this topic. Some people say the factory Volvo stuff is synthetic 5-30 and that Mobil 1 5-30 will work fine. Others say not to use Mobil 1 and to use Redline MTL. Does anyone know what exactly the factory stuff is? Would I be fine using either of the two? I am just trying to avoid paying $20 per liter for the factory stuff if there is something else that is cheaper and does the same thing. Thanks for the help!
