Acid neutralizing additives

[1911]

Hey Guys,

What additive/s in motor oil are used to give a high TBN number for acid neutralization? Is this additive/s highly soluable in the basestock?

Thanks,

There likely is a discussion of this in the "Question of the Day" forum here. Try searching on "TBN." Anyway, I am no expert, but will point out the obvious one, calcium, which also serves for cleaning and I believe antiwear to some degree.

Sodium, Calcium, and Magnesium Sulfonates, among others.

This one is old but really goes into detail on TBN and how it relates to oil quality and life. A quick scan of the article shows that Calcium is highly rated.

Oil Xtreme concentrate has a lot of calcium. Would think it would help neutralize acid.
