I am afraid that I am going to regret asking this question-- but I just changed the oil in my wife's 80 and it came out looking like it had a significant red tint to it. It is a 93 with 134k miles on it. The oil was just some regular old valoline semi-synthetic when it went in-- I am pretty sure it was without a red tint going in.
Other than having a red tint the oil looked normal enough.
It doesn't overheat, and when I last did the bubble check it came out fine. No noticable loss of coolant.
The only thing that may be unusual is that it seems to burn more oil then normal. I haven't been good about tracking this-- but I would say once every month or so my wife mentions that the oil level light came on briefly after startup-- not to be seen again for the rest of the day -- so I will add half a quart of oil and the problem goes away. Like I said, I have not been responsible about tracking how often this really occurs-- so that is really guess.
I didn't think about doing a blackstone test until after I saw pondered the problem. So I saved some oil, but only after it had been sitting in my dirty pan for a while. I can't decide if it would be worth it to send in a potentially contaminated sample.
So back to the basic question-- does "normal" used oil ever have a red tint to it?
