Zinc additives

acutally jiffy lube is for the lazy *** people who dont want to change their own oil when they can save alot of money or dont have time to do it
It isn't just lazy people. Some people know nothing about cars and are scared to learn while others are just too busy. I came home a couple of nights ago and saw a huge oil slick under my neighbor's Honda. The Chimpy Lube guys forgot to tighten his drain plug. Lucky for him that no damage was done.
