Thanks. Sounds right.I do not have Noack and do not run them for the most part. We use good base oils and therefore we do not run into the issues of volatility as compared to someone trying to squeak by with lower quality base oils. We do run TGA against a high quality competitor to be sure of where we are.
I think it is fair to say that a 1/2 quart of makeup oil in 17,000 miles in this case is certainly an indication we are pretty good in the volatility department.
Thanks for asking
