Just to sum it up quickly, CNN claims this product cleans your oil constantly, thus making it so you don't ever need to change your oil again. And it some how increased gas mileage. I guess it's been used for years on ships, and is starting to make its way onto commercial vehicles. Can this possibly be real?!
So, I trade out swapping 5 quarts of oil every 3-5k for a "filter pack" every 25k? Guess it really depends on the price/availability of the filter pack, and how much of a metric pain in my ass they are to change.
Um, don't all the fancy additives and stuff in oil break down over time? Oil doesn't just get dirty after 7k miles, It looses its effectiveness. I don't see how a filter will fix this.
yes.
The sort of vessels that seem to be running this system all appear to be running on heavy oil (ie, something that already lubricates quite well) and are very slow revving so you probably don't need to use extremely engineered oils in those engines like you need to do in your car engines.
OTOH, given that most people seem to consider a 100k mile car worn out, this might just work for the "vehicles are appliances" crowd.

Supposedly motor oil looses it effectiveness because of contaminates, not due to the oil it self (which sounds fishy to me). I suppose if it really works as well as advertised, you wouldn't need all the fancy engine cleaners and additives. If there's no gunk going in the engine, you don't need to clean it away. It just sounds way to good to be true.

Don't long distance diesel trucks already typically use a bypass filter setup so they can get 25k+ out of an oil change?

All of the commercial diesels that I have worked on had at least two (sometimes three) VERY large filters and held around ten gallons of oil. Even with that volume it was dark brown upon initial start-up, immediately after a change. The company I worked for shot for an interval of 15,000 miles but it was usually around 20,000 since the trucks were always moving...at least they should have been.
I've seen what happens when customers skip oil changes and this product would have no effect on the end result.
There are many people who have no interest in opening the hood or have a desire to do preventative maintanence so the engine becomes full of sludge and/or it runs out of oil. The sludge happens because the antioxidants in the oils additive package get used up and can no longer prevent oil oxidation and thickening. Modern engine still consume too much oil and few engine have an oil level sensor to warn of this.
I know some OTR truck companies use a centrifuge to clean the oil, then put the worn out additives back and keep going. Oil change intervals are as high as 100,000K miles. But yes Tommy, I think you have to put those additives back or you are loosing some effectiveness. I don't know, changing my oil every few months doesn't seem THAT big a deal. That way I can have a look-see at the dirty side of my car and check for worn this and broken thats.
US Navy Wichita-class replenishment oiler (AOR): We had DeLaval centrifugal oil purifiers on a 600 PSI dual high/pressure/low pressure steam turbine system (to clarify, one high pressure turbine and one low pressure turbine turned one propellor shaft); we used an oil called 2190 TEP. About the viscosity of 10W 30 IIRC. We still had to add oil periodically and still clean the reduction gear sump.
