yea I thought the same thing. The only thing I liked about it was I use
synthetic and synthetic doesnt hold dirt or metal in suspension like dino oil does. So
if you would flush once a year it should grab all that metal and dirt that
lays in the out of reach places and hopfully not end up in the bearing
races.
Not sure who told you that story John, but it isn't true. The synthetics that meet the current SAE and API specifications have the same detergent properties as the dino oils. The specs aren't different for syn versus dino.
As for the extra flushing, since there are no definitive long term testing results either from this company or better yet from an independent testing company, your guess as to any real benefit is as good as anyones. I tend to look at it this way. If you want to do an annual "extra good" oil change, just buy a couple extra quarts of oil and after draining the old oil pour the two quarts in and fire the engine up for a couple minutes, then drain again. That should ease your mind about the few ounces of "dirty" oil that was left in the crankcase and cam chest, and you could do that for more than ten to fifteen years before you would spend the same amount those folks charge for their device and the extra oil it uses during the flush cycle.
It's a slick (no pun intended) idea, and I can definitely see how it would appeal to a compulsive individual (like I used to be). But while it won't do any harm, other than to your wallet, I don't see where it would do much good either.
BTW, assuming you run a decent oil filter, that dark oil they show in the ad isn't necessarily full of dirt and metal particles. You don't really change the oil to remove "dirt", you change oil to renew the worn out additives, and eliminate things like fuel and water that the filter doesn't remove.
