Re: Synthetic Oil
Werner:
"In short: Poly(ethylene)glycols form aggressive acids during combustion. Therefore, such oils are more additized to corrosion protection. An alkaline additive is added. That neutralizes. It consumes itself in constant circulation. Measured to control the basic buffer, TBN (Toatal Base Number). "
What is the life span, in months, of the alkaline additive, or does it depend upon the amount of driving. I am just curious about this.
