Review: I use this as directed for my 1999 Jeep 4.0L - I use this as directed for my 1999 Jeep 4.0L. Lots of critics on if its really needed, but as far as I am concerned, its better than finding out later Zinc was needed. Priced okay, hoping it works, I use it with semi-synthetic Pennzoil. I have 179,000 miles and still rolling.
