Oil filter magnet

[Vern]

Thats as may be.. however - from all I've read over the years. the standard filter is more than adequate. The chap on advrider who's now up to 419,000 miles does nothing special. (apart from ride his bike a LOT)



And he is just the latest in a long line of mega-mileage riders who have said exactly the same thing...

So.. yes. a magnet filter like yours sounds great and shows results.. but whose to say it actually extends the life of the engine.. it might conceivably do the opposite... this fine paste thats too fine for the filter - could just be what keeps mister 419K's engine looking like brand new. It certainly isn't doing any harm.

(hows about THAT for reverse logic)

That's not reverse logic,that's total bollox.

there's a lot of that in this forum.. I've been here too long - obviously.


edit. of course it's bollox. but then so is putting a magnet in your filter and thinking it will extend the life of the engine.

Of course it doesn't... but if people want to think it does.. fine. fine.

if an oilhead boxer can do 400,000 miles and look 'as new' exactly by how much do you think a magnet will extend the engines life? and will you live long enough (or own it long enough) to find out???

my rule of thumb is, if its of any real use, it would be fitted by the manufacturer.

I have heard they are fitted to some aero engines - not as filters but as an early warning of mechanical damage.

i.e if you find a gudeon pin stuck to it, you may need to ride a touch slower.

But I'm sure it does no harm.

I wonder if stuff sticks to the magnets of internal Jap altenators ?

and what is the filter pore size on a GS filter ?

Interesting bit of info from K & N "Gold" oil filters, this is a direct quote from their literature.....

Pleated synthetic media removes 99% of harmful particles....

Sooo that being said, 1% of harmful particles are circulating..

I love this forum, it sometimes makes me change preconceived ideas...Where was that magnet thing again ??

 

[turnipbmw]

I wonder how much gold is in my engine - might have to do a bit of 'prospecting' after the next change

 

[Vern]

All I can say is that you haven't been inside many trashed engines!

Manufacturers wouldn't put anything on that would cost them money,infact,they pare everything to the bone to save money,and we're talking 0.001pence per unit,not 50-60 quid.

 

[turnipbmw]

Actually this is quite an interesting subject - been looking up a few details.

removing extra small particles can give an improvement of efficiency/mpg

but I also found details of an American 400,000 mile truck engine test where the oil was not changed.

No significant wear found.

I guess like all tests, results can change depending upon sponsor.

Will be sticking a magnet to my oil filter and checking results.

 

[alimey4u2]

I fitted this because ? EH... it looks the dogs boll*cks. Filters well too

 

[turnipbmw]

I think both wheels would be off the ground on a GS with one of them !!

DOH!

I've got a Magnom www.magnom.com magnetic filter on mine.It fits between the engine and the oil filter,so all the oil has to constantly pass the magnets and blades to get to the filter.Every time I clean it,I'm horrified by the ammount of crap stuck to it.

Sani,as for the engine being made of aluminium.I think you'll find that the cases are made of aluminium,and just about everything else is made of some type of steel.I don't think aluminium cam chains would last very long,and aluminium valves aren't to clever either

200k and still going strong

Vern
Which type do you use, who supplies them and how much do they cost?

 

[Vern]

Just go to the web site and give them a bell and ask for one for a GS.I bet they know how much they are as well!

Mine has been on there years,so anything I have on them will be well out of date.

Try ripping old computer hard drive magnets.
Cheap and damm strong magnet.
Fix it below the oil filter.
After your normal oil filter change, cut it open.
I saw some metal powder but it has lessen a lot since my last filter change.

break an old speaker magnet up theyre strong enough as well

 

[jimbo]

I can never see the point in putting new oil through an old filter.

I always change both together, but oil 'age' as well as picking up bits of rubbish:
- the oil gets contaminated with the stuff that blows past the piston rings
- enventually the oils viscosity will reduce - polymer chains being severed maybe?
- magnet or not, there will be micro particles that remain in the oil

So in theory at least if you an over-sized and efficient oil filter, changing the oil on its own is a valid thing to do.

I did actually say in the post that he is referring to that I change the oil every 3,000 miles and the filter at 6,000. Its an uber cheapo own brand mineral £8.49 for a 5Litre pack. so is still far cheaper than a branded oil - even though its the correct spec. These engines don't need that level of care... but with the oil so cheap. why not?

Since Fitting a magnet to my oil filter I have seem my mpg soar to an average of 87.8 mpg on a run, performance and accelertion seems up a lot too, the 0 to 60 time has definatly improved, used to be a slug away from the lights , (about 8.5 sec best 0-60) now its 0 to 60 in 3 sec flat, all for the sake of a magnet !!
I have been so impressed with these magnets that I have managed to obtain several thousand and can offer them to UKgser`s for the remarkable price of £7.99 each, plus £30.00 P&P (their quite heavy)
