Lucas Response To Zinc Additive

A friend of mine has a shop here in town. He told me that he could tell a motor that had run a "lucas" additive. He said that it all ended up in the bottom of the oil pan.

This gentleman has ALL the certification Diplomas for auto and diesel so I trust him. I just run Valvoline racing oil. I change it every 4 races and my 340 has over 1000 passes on it. I pulled the pan after the '08 season and it still looked good. I was actually quite suprised. :-D
