There are lots of these types of magnets around. The most functional one
that I've seen is a magnetic oil plug. That way, when you unscrew the
plug to change the oil you can wipe off the metal particals with a rag
before replacing the plug. Seems like a good idea to me. I saw this in
either JC Whitney or Summit, I forget which. It was only a couple of
dollars.
Anyone tried one of these?

Yep, garbage in the oil is definitely a problem. I've heard of some
people who put magnets on their oil filters which supposedly will trap
some of the metallic particles. Anyone know if this works? Or could this
do any harm? I'd give it a shot as long as I'm sure it won't break
anything,
even if the gains are minimal. The one thing I can think of offhand where
it might cause harm is, say the magnet has collected a bunch of fragments,
and
then it falls off. Suddenly, all these fragments are no longer spread
throughout the oil, but they're going through the engine at the same time,
in one big clump! Sounds like a recipe for disaster to me...
On a related note, does anyone regularly cut open their old filters to
inspect them? This is done quite often in the aviation world; I was
thinking
of starting to do this... I'm too cheap to buy one of those pricey oil
filter cutters though; I'd have to use a hacksaw and gallons of elbow
grease.
:-P

Well, I am single with no family, but I don't have a really well paying
job, however... I change my oil and filter every 3,000 miles. I use
Mobil 1
synthetic and I've been using Fram filters. Probably overkill, but I
consider it worth it. Just a quick calculation here: If I assume that I
will
keep my truck for 100,000 miles, and that dino oil (Mobil 1) costs $1/qt.
and
syn oil (Mobil 1) costs $4/qt, the additional amount of money over the
life
of the vehicle would be: (5 quarts per oil & filter change)
($4 * 5) - ($1 * 5) = $20 - $5 = $15 per oil change
100,000 miles / 3,000 miles = 33.333... oil changes
33.333... oil changes * $15 per oil change = $500
If I were to drive 20,000 miles per year, that'd be $100 per year, or
$8.33
per month.
For me, that isn't cost prohibitive after I factor in the peace of mind
that I get from using synthetic oil.
