This is for a motorcycle application, (05 Victory Hammer )
The mfg says this dual woven T305 stainless steel filter
will filter (25) microns, absolute, with no restriction.
Bypass to open at 16 lbs, OEM bypass said to open at 6-8 lbs
They claim a average of 5HP on a large V twin motor, because
of the LOW restriction on the oiling system. The filter
also has 2 built in rare earth magnets. The aluminum body
is said to help in the engine cooling. The cleanable filter
is claimed to be a LIFETIME filter. My question is, is there
a reason NOT to run this filter?? I do not mind cleaning the
filter, and the extra cost is not a problem, I just want
the BEST!! is it? your opnions PLEASE! Thanks you, Alex
 
I wouldnt use it, personally. The "5HP" number sounds really dubious. I really doubt a filter could make any where near that much difference. Why, if it is so low restriction, would they increase the bypass psi? Also, most rare earth magnets are neodymium and those lose their magnetism at about 176*F. There are higher grades of neodymium magnets and also Samarium-cobalt which work to higher temperatures, but are more expensive and they dont say which kind they use.
They sound like a gimmick to me.
 
I'm jaded, too. When they use superlatives like that, with claims of 5HP, etc., my brain classifies the product as junk...although it might be wonderful. I wouldn't buy it.
 
I don't have much faith in lifetime filters. Not that they aren't capable of ding the job (although I doubt it), but rather that they can never really justify their existence in the utility that you can get out of them vs. regular filters in costs. Costs in cleaning products and whatnot aren't even factored into the cost:benefit deal.

Buy it and find out..

Do a particle count on your oil before and after the installation. That will tell you if it's doing a better job filtering.

Look at it this way. You'll be the guy who made the bold move for the good of Victory riders everywhere. You'll either prove or debunk the value of the thing ..at least in terms of filtration.
 
I agree with all of the above comments: I replace screens every week.. Stainless mesh has very limited dirt capacity, must be cleaned often and are not in the same world as the Amsoil EaO oil filter discussed at length on this site... Just pay yer $12.00 for an EaO and smile going down the road knowing that you have the finest filtration money can buy...

I agree with Pablo on the cost basis of them. I have looked and looked at various lifetime filters, and could never justify the initial up front costs of the filter and or element, because you do have to factor in cleaning, and unless you want to add chemicals to your oil right off of the bat on your OCI, you need 2 elements so that you have a clean AND dry one to install back into the housing.

Now, as far as convenience goes, some vehicles, it sure would be nice to just be able to take out an elements as opposed to changing the whole filter, but on most (not all) vehicles, it's just as easy to just unscrew and replace a disposable oil filter.
 
"Lifetime filter? No such thing."

Nor should there be.

Don't be too quick to judge. I've got a sample going to Terry with a PurePower filter for 15k miles. I'm not so sure that they should be dismissed out of hand. Do you have some test data that might give us an answer?
 
Test data? It better include particle counts.

Woven mesh stainless screen filters are great for flow. Oil flow protects your engine. But, if there isn't enough filtering, at what point does the flow protection succumb to the suspended wear in the oil?

BTW, I only recommend those 'lifetime' filters as an option when there is a bypass installed to keep the oil clean.
 
I use a scotts stainless filter in my dirtbike, was I believe $60, never had any issues with it and with frequent oil changes as I do on the crf I just assumed it would be worth it. I have probably changed the oil about 10-15 times since I bought it last year.
-Thought about gettign one for the ninja but $120 was a little tooo steep for me
 
mesh screen filters are a race track (nascar) item, which were recomended by Smokey. He stated that paper filters caused aeration of the oil during sustained high rpm operation and the mesh screen filters did not. This is the reason why the paper filter makers came out with high flow ie large pore race filters.
Another race track item that snake-oil salesman are selling for a street car.

What info did you gain from you sample? TIA Alex
 
The thought of cleaning out the mesh seems terrible. After I use solvents...the solvent residue remains (wash with soap/water ?)

I suspect holding capacity and filtration (microns) of stainless will never approach synth/glass media.

How much horsepower is used by oil pump? I can't imagine it would take 5 HP to run the oil pump and most restriction is not the filter.

In racing I could see using dry sump (save HP and cut aeration) with separate reservoir. The scavenge pump could then be high flow rate in which reduction of filter restriction could be beneficial.

Well I cleaned my Purepower filter today, and was "amazed" to see how much debri the filter had caught, and my engine normally runs in the 200-225*F range, the magnets were loaded with metal particles, so that blows that 176*F statement out of the water, the magnets are strong as they ever were, I'll be sending my oil sample to Blackstone for the test, and report back in the near future.
