Does anyone have any experience with this product? I am going to make the switch to synthetics (haven't decided between Amsoil and M1) and I have read that this is a great additive to prepare for the transition? Suppose to be a great product for cleaning sludge and varnish from the internals, not that I expect I have too much www.auto-rx.com

You'll find a lot of discussion on this. "Frank" the owner of Auto-Rx posts there along with a lot of people who are using the product.

I'm currently trying it in my Pathfinder that has 215K miles and I use the 3oz "maintenance dosage" in my 4Runner every oil chage...
