Re: Follow-Up on Mobil 1 Oil Filters

["Michael Stocker" <mdstockr@neo.lrun.com>]

I came across something like that a couple of years ago.

If memory serves me right, the filter media was a roll of toilet paper.

The issue that I can see is that oil additives start breaking down after 3,000
miles.  A 10W40 oil becomes 10W after a period of time.

So, for this system to work, you need to be able to replace these additives
periodically.

| There's a new kind of oil filtering device...it's a big can, maybe 3x
| longer than a normal oil filter, and it has a small pump...it hooks into an

| Mostly designed for trucks, but I've seen it(I think) in various race cars.
