I bought my car with around 61k miles on it, so I don't have the details on what oils have been used. And I bet the PTU and RDU have never been changed. Looking around on here I heard good things about Amsoil and their yearly membership. If I go that route I might as well use them for all the fluids, lol. I searched around and found what fluid I'm going with for motor oil. I haven't been able to find much in the way of what fluid to use in the other locations. I live in Central Florida so it's fairly warm. What Amsoil fluids do folks recommend for PTU, RDU, and transmission?
