This is, arguably, as close as one can get to controlled study, in a "real" world environment. One driver, similar ambient temperatures, comparable mileage and driving conditions, at least 2 runs for most brands of oils.
Those UOAs compare results from some of the "more" interesting oils under scrutiny on this forum.
The intent behind this post is to seek comments and suggestions given rather interesting results. Note that RLI results include both TAN and TBN.
Thank you in advance.
