Reply to "What are acceptable TAN's"

Hi Chris, rather than just change the oil check your test history and if you are increasing the TAN by more than 0.75 per month then the previous replies are correct,
if the TAN is above 2 but not increasing I would complete a WDA and particle count and if both normal, don't change but monitor,
The key for change appears to be a steady increase in TAN value every test and of so rectify by change.
