Hey guys, anybody have any experience or know anybody that does with one of those magnets that is simply attached to the side of your oil filter to trap tiny metal particles and keep them from recirculating into the engine? It's specifically for new cars, but can be used forever.... it makes perfect sense if you think about it, but do you guys know if it's worth the 30 bucks or not?

thanks

 

you can make your own for a couple of bucks...neodenium magnets are like 2 bucks a piece

 

Can't hurt. It's only $30 if it makes you feel better get one.
I am a member in the 'If it made a big difference, filter makers would have already added it to their product.' camp. A good quality, functioning filter will remove harmful size particles from your oil. That is what they are made to do.
edit: Oh, and I just noticed. Congrats on your first post!

 

haha thanks, i actually dont even have a G yet, (broke college kid still driving first car since he got it 5 years ago) but the parents are trying to get me one soon, so im hopeful for my upcoming birthday..... anyway, i joined here so i can learn lots of useful stuff before i put a mile on it

 

if you do have shavings it will keep them in the filter...but save yourself some money and go buy a magnet and make it yourself

 

The particles being stuck to the wall of the filter with the magnet is the same side as the input flow to the filter (oil flow in the filter from the outside and exits through the center). So basically, all that's being held by the magnet would be trapped by the filter media anyway. I think they try to mislead you in that what's being held by the magnet will get recirculated into the engine, which isn't true.

 

Lets think about this a minute, The VQ35 is an Aluminum block, pistons, rods, etc. The Rod and Crank bearings are Bronze (i think). So, why do we need a magnet on a motor that is composed of nearly all NON-FERIOUS materials?

Now the Transmission....

 

My 2 cents...
Spend the $30 on a Fumoto drain plug valve. They're high quality, well engineered, and make oil changes much easier.

 

I have seen a few of those "types" of plugs. Some were good, some not. The only question I have is, does it REALLY let ALL the oil out, or does a 1/2 pint stay in the pan because the exit hole sticks up inside the pan?

From the website:
Q. Does my Engine Oil Drain Valve protrude into the interior of the oil pan and prevent full drainage of my engine oil?
A. No. The threaded oil drain plug hole is always reinforced to accept the threaded bolt of the drain plug. In most cases, the Engine Oil Drain Valve will not extend past this threaded portion of the drain hole and will allow the oil to be properly drained. Your Engine Oil Drain Valve will let you drain your engine oil while it is hot without burning your hands and it is much more effective than trying to pump the oil out from above

 

That's a good point.

 

Now that's CooL!

 

Cylinder liner, piston rings. Some of the highest friction surfaces in the engine(due to lack of direct pressurized oiling).

But, I think vjquan has the right idea that these particles would probably be caught by the filter element even without the magnet installed.

good point...very good point...

 

another thing to think about is that if this was at all more effective than the standard filter, why wouldnt it come stock since it would be so ridiculously cheap to do?
