Re: Diesel Oil Filter?

[drew <drew@dyermaker.cs.uoguelph.ca>]

I've been following this thread with some interest - seeings how I've been
a longtime user of VW diesel filters - on VW diesels!

I presonally don't believe that it's appropriate (or necessary) to use the
diesel filter in the gas environment.  It would be interesting to see the
detailed specs on each filter (element size etc. etc.)

The one thing that I know about diesels is that they accumulate soot
particles in the oil, as a result of compression gases blowing by the
piston rings.   The greater the mileage (or hours) on the engine,
generally the greater the amount of soot accumulation in the oil.  Diesel
engine oils are specifically forumlated to retain (or control) this soot
in the oil, to prevent it from escaping into the environment or building
up on internal parts (these are the C group of oils - CD, CF, CH etc.)

Obviously the diesel oil filter is going to be contructed to allow this
soot to pass through (to a certain degree, depending on particulate size)
otherwise the filter would  very quickly clog up.

It may be that these particles are way too small for any filter, I don't
know - but I'm certainly not going to take a chance on the diesel filter
passing larger particles than the gas filter, so I just run gas filters in
my gas cars and diesel filters in my diesel cars, despite the fact that it
would be easier for me to just keep one filter on the shelf.
