 Dear Tom and Ray: I recently
                saw a car catalog that had an oil-filter magnet
                for sale. The magnet was placed on the bottom of
                an oil-filter and was strong enough to remove any
                metal shavings from the oil stream. Is this
                product worthwhile, or am I just wasting my
                money? - Ron TOM: These things have been
                around for years, Ron. They dont do any
                harm. RAY: They sell magnets that go
                inside the oil pan, magnets that are built into
                the oil plug, and magnets, like this one, that
                attach to the filter.  TOM: Now, keep in mind that the
                oil filter itself already removes any metal
                shavings, or anything thats bigger than
                about 25 microns - or about half the width of a
                human hair. So they do a pretty good job.  RAY: Does stuff thats
                smaller than that harm your engine? Probably, at
                least a little. But with the magnet, youll
                only get the metallic stuff that sneaks by the
                filter. You wont catch any soot or pieces
                of aluminum, which are also harmful. TOM: If a magnet really made
                engines last longer, dont you think that
                Ford would already have spent the three cents per
                car it would take to build one into the oil plug? RAY: So, Id have to say
                that oil filter magnets fall into the category of
                "overkill." TOM: But if youre the
                kind of guy who believes in overkill, Ron, then
                go for it. Do you wear a surgical mask on an
                airplane? Do you go back and double check to make
                sure youve turned off the stove before you
                leave the house? Do you have your brother taste
                your food before you eat it? If so, you should
                get one of these magnets. RAY: In fact, you should get
                two, in case one falls off.  TOM: Seriously, though,
                changing your oil regularly will probably extend
                the life of the engine more than any magnet.  RACINGBy Greg Zyla

 The Art of
                Racing Vintage Sports Cars Carl Jensen is competition
                director of the Sportscar Vintage Racing
                Association, one of the most respected vintage
                racing groups in America. Headquartered in
                Decatur, Ga., the SVRA is dedicated to presenting
                safe, exciting and historic racing events with an
                emphasis on actual racing (check it out at
                www.svra.com). ZYLA: Carl, how would you
                describe vintage sports-car racing? JENSEN: Vintage racing is like
                fine wine or, better yet, similar to a great
                painting from Van Gogh, Picasso or Monet. I
                relate them to Porsche, Ferrari and Bugatti --
                all great artists, all great car builders. ZYLA: Unlike other
                organizations, which conduct on-track
                demonstrations or "driving" displays
                with historic race cars, the SVRA actually races.
                Do you feel this is why your organization has
                been so successful? JENSEN: Yes. We race the cars
                just as they did in their day. This is really a
                big part of the attraction to the owners and
                fans. The racing can be just as intense as say,
                SCCA, but the difference is we strongly
                discourage running into other cars or other
                objects. Some of the cars are, of course, very
                valuable. ZYLA: How about special races
                at events? JENSEN: Almost every event has
                a special gathering of cars. We did MGAs at
                Sebring because it was their 50th year of racing
                at that venue. We are doing the 30th anniversary
                of the Sport 2000 at Road America, and we have
                150 already entered.  ZYLA: What are you most proud
                of? JENSEN: The fact that we
                continue to run Vintage racing events that are
                safe, fair and fun. Some people collect art ...
                we race it! |
