need to change the engine oil in my wifes 1990 saab 9000 turbo, would this engine prefer some synthetic 0Wsomething? or some good mineral 15w40?
while I'm asking about saabs, the power steering fluid needs topping up, the haynes says "saab power steering fluid", alot of bloody help that is. is it hydrolic fluid like the dot4 (or is it 5?) I use in the clutch and brakes in my land rover? or how about atf as in my land rovers power steering? or something else?
Regards. Mark.(AKA, Mr.Nice.)
