I worked in service for two different Ford dealers. The JB engine tune up is a great product. Its not just a thick oil with additives...it's rather thin. Perfect for today's engines that require thinner oils for proper flow and lubrication. What it does is bonds to metal parts and reduces friction. A Justice Bros company rep brought a simple powered device where a metal lever would apply measured force to a rotating metal wheel...direct contact friction. He encouraged us to bring any kind of oil/additive we could find to test against his product. We tried everything from various synthetic oils to STP, Lucas and Slick 50. No matter what we tried, the JB metal treatment beat them handily. More PSI of pressure could be applied to the lever before the rotating wheel would stop. That sold me...have been using it for years. Not a "magic" fix for neglected and worn engines...but if you take care of your vehicles it will add many miles of wear protection for all the internal moving parts that experience friction.

I've ran this twice, back to back oil changes in my wife's equinox with 2.4k. It helped lessen oil usage in it from 1 quart every 4K miles to about 1/2 a quart. I'm figuring that it helped remove buildup from the piston rings. I plan on a treatment every 10k with this stuff.I also used it in my 2009 Silverado with 5.3l and it helped lessen my startup lifter tick probably by cleaning deposits from within the lifters.
