Hi All - I've actually been watching this Board for several months, learning alot and enjoying the informational resources provided by the members of this Board and its sponsors. I've been using Saab Turbo Oil (full synthetic, not the blend) in 0W30 for almost all of the 50,000 miles on my normally-aspirated Saab. People tell me it's overkill, but I figure that spending the extra money and being religious about the OCIs (every 5,000 miles or less) will eventually pay off with a 400K+ mile car, which is what I'm aiming for. Unfortunately, Saab will no longer be importing this oil into the States, so I am going to be forced to make a switch at some point. My question is this - should I even bother to do a UOA (it would be the first for this vehicle) prior to switching oils, or should I just go ahead and switch, and then get the first UOA from the 2nd batch of new oil that I put in the car? Thanks in advance for your help.
