You folks have got me all confused on filters again.
Uh-oh ....
I can recall some of the Toilet paper rolls for oil filters from many a year ago. Seemed they went out of fashion quite quickly.
Yup - in the world of "Madison Avenue" Advertising and Public Relations (which is often fraught with misleading info - if not blatant, outright lies) toilet paper as a filtration medium wasn't exactly great "positioning" - it lent it itself to much derisive commentary, and "potty humor" .....
Of course, that completely skips over and totally ignores what the
actual results were, and that, as a matter of course, paper itself as a filtration medium isn't an uncommon thing ...... it just can't be
that type of paper:
NOOOOOO !!! .... Henry please, please tell me that you didn't put that paper in my Ford ..... :laughing:
One has to ask themselves:
Who would be interested in seeing such a product not succeed ?
Two parties come immediately to mind:
1. People/companies that refine and sell oil ...
2. People/companies that make and sell a different type of filter .... (one that is much more expensive, in terms of replacement)
And there is a third factor which plays into it, and goes back to a comment that I made earlier in this thread, which has to do with the efficiency of a filtration media to capture dirt and contaminants, and is part of the "magic triangle" of filtration:
Filter efficiency vs. overall size of the filtration media vs. filter longevity (frequency of change or replacement)
If a filter is extremely good at capturing even the smallest contaminants, it is not going to last as long as one which isn't, given equal sizes of filtering media and the same dirt load - because it will clog up and need to be changed sooner.
People, to some degree, are often lazy - vehicle manufacturers, realizing this, then figure out a way to come up with a so-called "better solution" (albeit a more expensive one) - which allows for changing the oil filter less frequently (but changing the oil more often than one would actually have to, if one were using a better filter) - and then this is sold as an "advantage" - even though it results in poorer filtration, costs more overall, and allows wasting a valuable, finite resource.
Dependency on foreign oil a problem ?
Well, consider this: In the United States there are roughly 247 million registered motor vehicles on the road today - cars (136 million), trucks (110 million), and buses (1 million) - which doesn't even take into account other things like tractors and construction machinery, etc.
Let's just look at cars - since it is doubtful that very many of them are running a bypass filtration system (many larger trucks and busses probably already do run one - since the economics are more significant, in terms of a commercial operation)
Now imagine that you eliminate 2 out every 3 oil changes (a very conservative estimate) .... figuring an average sump size of 5 quarts .... that's a total savings of 1,360,000,000 quarts of oil (yup - that
BILLION with a very big capital "B") .... or 340,000,000 gallons of oil .....
That is not an insignificant amount of a finite resource, nor is it an insignificant cost (to our economy)
The real beauty of the MotorGuard system is how cheap replacement filter media is, and how relatively clean and easy it is to change:
Let the filter drain for 30 minutes or so after the vehicle is shutoff, unscrew the T-handle and swap the media and reassemble - the actual media change takes maybe 5 minutes ....
if you are really slow ....
Of course, as with anything, the proof is in the pudding of
actual results
