Magnetic Oil Filter

[bangahh]

Has anyone used it and does it really work? if so,

Im gonna make my own, with hard drive magnets :-)

[mindflux]

Interesting Idea

[knore]

what a good invention using common sence

I cant beleive this hasnt been done already, its a simple concept

Anyone know how much they are and where u get them?

[meshmesh]

Funny that, I was looking at something similar... but then I stumbled onto this site...

http://homepage.ntlworld.com/cains1/Fuel_saving.htm

[ferni]

meshmesh: Hmmm i can't see anything on that site that says anything about magnets around an oil filter..

that sit seems to be about fuel additives etc.. not cleaning shavings out of your oil.

[meshmesh]

Yeh I know, my mistake, but as I was looking for some info on fuel catalyst I also stumbled on this along with a number of sites, that also sold fuel catalyst along with these magnetic oil filter thingy's.

Here's a sample of another magnetic thing - http://www.fuelcat.co.uk/turbo-mag/products.html

I found that original site I posted above, a very interesting read, he goes onto to explain a number of so called "miracle wonders" product for cars..

[ferni]

I have to agree tho, not a bad idea, it couldn't do any harm, but i don't know if there is anyway to really test it hey

[meshmesh]

Why couldn't you just stick a strong magnet to the oil filter, rather then paying for one of these? After thinking about the idea/purpose... I wonder whether the magnet could effect oil distribution, oil flow or attarct other things in the oil?.. That's ofcourse if oil contains anything magentic

Run castrol 'Magnatec' through the bitch and see what happens

Didn't read the lot but that guy has writen something wrong.

PPM is parts per million, this is a metric measurement, so if you are pumping out 10ppm of fuel and you did something and ending up getting only 5ppm of feul coming out then that is a 50% saving in fuel usage.

I have no idea what the 1 part in 5000 this is also wrong, as 10ppm equals 0.038 gals, and 5ppm equals 0.019 gals.

PPM stands for Parts Per Million, it is a metric term, you can also use another much easier to understand metric measuement if you wish, and that's mg/l or milligrams per litre.

So to put it another way...

10mg/litre of fuel used, and do something and get an end result of 5mg/litre this is also a 50% saving.

This guy doesn't know his measuements as most US people don't know jack about the metric system at best, so he shouldn't really be claiming jack about a 50% saving being BS if he can't even understand what the measurements are for a start.

Also reminds me of another US D***H*** claiming to know the metric system and claiming 5'8" equals 70 inches and therefore equals 170cm, when this is in fact incorrect and will equal 174cm.

I guess he didn't know that an inch is really 2.5333r, so be careful if you have to convert measurements around.

1 ppm = 1 mg per liter! ie weight/fluid vol

But yeah the Filtermags are a good product. The only problem is the cost an absolute fortune! I think you're best off just chucking one of those lil supermagnets from Jaycar onto the sump plug and leave it at that. The filter will do the rest...

I have been running magnets on ALL my oil drain plugs for over twenty years, they work great. Every time you change the oil there is a big fuzzy blob of steel crap sticking to the magnet. I would much rather have it there than going through the bearings and gears, or having it clog up the oil filter.

Do it yourself !

The strongest magnets available these days are the Neodymium Iron Boron rare earth magnets, and you can get small disc ones for around a couple of dollars each, that stick by themselves to the steel drain plugs. These things stick so hard to the drain plug you need pliers to get them off.

I have five on my car, sump, gearbox, transfer case, front diff, and rear diff.

Warpspeed,

Thanks for that, but can I ask what size magnet you're using for each application?

[ferni]

warpspeed, where exactly did you place the magnet? inside the tank?

[Warpspeed]

The part I used on all my sump plugs was the 12mm x 5mm size (part number 3140).

This easily fits in the middle of the drain plug which probably has about a 16mm thread, not really sure of the exact thread size. I have been using these for a very long time. The magnets are very light in weight and strong, and will never move once stuck to a steel sump plug.

If you stick the magnet to the drain plug, will it catch all the metal bits? Obviously it will catch whatever comes near it, but metal has to travel down through the engine first, where it may get stuck.

[GTRgeoff]

It'll only get the ferrous bits, and the hope is that there will be none of that, only soft metals.

Anyway I'll be getting some.

[meshmesh]

This may sound a bit silly, but will these magnets cause stress, extra resistance on the internals?

PS: Just Slap me (not too hard please) if that is a dumb Q :slap:

[Greg]

I was thinking the same thing... one of the filter magnets mentioned was something stupid like 1000 pounds strength. But apparently the design of these concentrates the magnetic force just around the filter, nowhere else.

At this stage I'm thinking of sticking a super strong magnet to my oil and fuel filter, and drain plugs.

[Warpspeed]

What sticks to the magnets looks like a sort of grey sludge, not like metal at all. But obviously it must be either microscopic steel or cast iron particles or it would not have stuck to the magnet. It is easy to do and there are no disadvantages. A lot of good quality production cars and trucks actually have magnetic oil drain plugs fitted from the factory. This is nothing new at all.

It is probably of more value in the gearbox and diff than in the engine. That last missed gear change probably chipped away a few microscopic particles of super hard steel. Those chips are going to circulate around and around in the oil, being squeezed between the gear teeth perhaps breaking off more fragments. Not very nice.

At least the engine has a filter and the oil gets changed, but what about the diff ?
