ZDDP Plus Oil Additive 10-Pack
Product Review (submitted on April 8, 2013):
I am planning on getting my oil analyzed shortly to see how much is actually in the oil when compared to original levels from a few years ago. It turns out many of the European performance cars strictly recommend using oils provided by their companies and discourage using any normal oil brands because this vital ingredient has been significantly reduced. Still maintained in high levels in off road racing versions, so all in all this product should be used in older cars as well perhaps new ones that are high performance models. So far this product performs well.
