Not real sure where to post this but here it goes. I was reading in the Diesel World Mag April edition 2009 and they have an article in there about Pure Power life time filters. I was just wondering what some of you guys thought of this. A couple of my questions are can they really filter out the dust and other little particles? I thought it was funny in the article they said they put a drop of water on the 5 micron filtering medium and it never soaked in, I was not surprised it did not soak in, put some pressure behind it and it will filter through the medium. Am I right about this or am I missing something? Are these filters really as good as they say they are? I just do not see how dirt and other particles will stick or get trapped in the filter since it is Stainless steel mesh. Obvisiously they will catch the metal with the magnets. What are your guys thoughts on this? Please shed some light on this cause maybe I am dumber than I thought.

 

Do you have a link for these?

so, youre talking about the oil filter?

 

Both oil and fuel filters.

 

Damn I dont know. I would be skepticle.


Whats everyone else think?

 

I dont think i would ever run a "lifetime" oil filter there aint no way

 

Modern injection pumps have the tightest tolerances at the moment. Common rail uses fuel filter down to 3 microns! So a stainless steel mesh it is not good enough for Common rail. Maybe as a pre filter.
It might be difficult to clean the mesh without ultrasonic devices. A degreaser or cleaner won't take out the contaminants.
I stick with the factory fuel and oilfilter or their aftermarket replacement and the change intervals to be sure eveything is safe or within limits.
Same thing with oil filters. If they would be good enough the military would use them. But they don't! They have the hardest operating conditions, and they stick with original replacement, because they can't gurantee the 100% correct cleaning of the filter media.
Whats wrong with paper or fiber filters? When in doubt- change it out. It's up to you.
By the way, those lifetime filters aren't cheap.
And it's proven that the smallest contaminant's (1 micron) do the biggest damage (Avalanche effect). If you wan't to stay on the safe side, use a centrifugal filter in the remote oil line, as used in full size trucks. Those are bad *** expensive, but their filtration is outstanding, no need for an extra filter media. Filtration is done through gravity. Only the housing is changed in intervals.
You will find them at Mann+Hummel.com
Typical german high-quality product, but as I told you very expensive...

 

Don' get me wrong. The Mann+ Hummel Filter is an additional filter for fine filtration.The existing main filter is still in the main oil line.
The M+H filter is working below 30micron. Thats where a usual filter stops filtration. So it keeps fine pollution like soot of the oil under control.
The Range Rover was the first (diesel)car with that kind of filter onboard. As a result of that the oil change interval was extended (doubled)by factory.
Especially your turbo will thank you for keeping fine pollution under control.

 

Good stuff..
