Here are my reports on engine oil analysis from my 246GT. Currently with a little over 70k miles total, rebuilt engine about 10 or 12k ago. I thought these data points might be useful to the group. First image shows 6 oil changes going back to 2008. Second image is of the 2 tranny changes I have done (tranny rebuilt same time as engine). If anyone else has oil analyses it might be helpful to post them here as a data bank. Image Unavailable, Please Login
The problem with oil analysis is that you need to perform several of them to see a trend, which you are apparently doing. Congratulations. What stands out in these reports is the comment section. Wow!, whoever writes like that is a valuable employee or perhaps it's the owner. In any case, I'm impressed. Everyone likes a bit hand-holding now and then, and a warm fuzzy feeling is not always easy to achieve. If this were my car, I would be happy based strictly on these comments. Somebody understands human nature. I got a smile on my face just reading them. It's nice to know that not everything and every person in the entire world has turned to cr*p.
