In Reply to: Lubrication Filtration. Is it necessary? posted by turtleherder on Saturday, December 10, 2005 at 1:32PM :
Oil filters often don't work as well as
we think they do. I would use the best
filter that I could get. How do you know
what's best? Some popular brands may not
work very well. A filter that removes
smaller particles tends to lower pressure,
all filters are a compromise between flow
and particle removal.
Changing the oil often is the safest way
to insure that the oil is clean. I'd
thought of building an external "dialysis"
filter that would use a higher quality of
filter so that I could get more miles from
expensive synthetic oil. My filter would
use a heater to evaporate water vapor and
some of the unburned fuel. This summer when
my car's motor was overheating I noticed the
oil returned to a clean honey color of fresh
motor oil. I figured the extra heat removed
unburned hydrocarbons as well as moisture.
The "cooked" oil looked and smelled like fresh oil. I think heat might actually tend
to clean contaminants from high quality oil,
something which a normal filter can not do.
