zam, I have been a proponent of NO ADDS to fully formulated oils for most of my analysis career.
Then I realized I mix and experiment all the time
some of it works well so why not share that with my non- corporate oil analysis customers.
Got to admit in custom formulating racing oils ,and consulting with major oil/add companies that some adds are save and effective if used properly and monitored with analysis.
Consider the fact that you can "air" an idea or mix here on this board as we have engineers,physicists, chemists, tribologists, and oil analysts that do the same thing at work( every day) that is discussed here.
MOST of the time it is best to use a fully formulated oil and periodically use something like Auto-RX to clean 500 miles before draining.
For the average motorist that plan is safe ,effective , and less expensive.
For the people here on Ed P's board the average is not good enough !
zam !
