i used motorcraft for a while but it seems like the k&n keeps the oil cleaner longer at least it did for mine n i got a case of k&n oilfilters from a guy for $100 $10 a piece so ill be going back to motorcraft or puraltor soon

cleaner as in? how black it gets?

I used K&N's for a few years on my old 96 and my 99. I used a Fleetguard I picked up at work after nobody in the area had a K&N in stock a few months back. Half the cost, and the oil looks, smells, and feels the same when changing, haven't used a K&N since. For the results I had noticed, the extra cost was a waste. As joebob3093 stated, keep it cheap, don't waste money on something only used for a short amount of time. There's many quality filters out there for less than $12.

what we need is a UOA to determine the truth on this "lifetime filter"

Agreed...that would be interesting to see this filter after 80-100k or so.

Lets assume for a minute that the filter can continue to filter out the particles that occur from engine use for the life of the vehicle. Fordornothing touched on the key to all this. Its the oil itself that will eventually let you down. As your motor oil is heat cycled and sloshed around inside your crank case and exposed to the hopefully small amounts of combustion gases the rather long carbon chains begin to break and the gases start turning your oil acidic. No filter can protect against these two things. The broken carbon chains are basically like trying to lubricate your engine with kerosene and acid has a way of greatly accelerating the oxidation process.

I would stick with a premium filter and oil and change your oil at the manufacturers recommended intervals. Cheap insurance for your motor.

i think the idea is that you still do the regular oil changes, you just need to clean the filter and reinstall it. no need to buy a new filter, IE: lifetime. the question is: does it filter as well as the disposables and flow more oil at the same time

^^^ Yeah I don't think they are using the old Frantz never change your oil marketing...I just struggle to see how a "cleaned" oil filter will filter as well as a brand new disposable filter?

Automotive filters are part of the throw away economy I am all for...:c:

ya know, i might be interested if it wasn't almost 500 bucks.

agreed if you watch the video on the link it explains a bit. i think theres something that comes with it to clean it out after every oil change and yeah the price is way to high its a new product so id just wait for a while for it to drop its a great idea im glad that people are still thinking of new products for diesel trucks.
