Oil filter Magnet?

Rooskey · 07-18-2012, 12:24 AM

Hey fellows im about to change my oil and wanted to add an oil filter magnet for safe measures. Can anyone tell me who makes a good magnet and what size I will need? I have noticed that some attach to the sides and some to the bottum of the filter. Which one's do you prefer? Thanks for the help

Yea I read up on that but just wanted to see others idea's on placement of the magnet. Not sure if it makes a big difference or not. Hopefully some people with some track time will chime in.

Track time? I think you're giving the magnets too much credit.

What I mean by track time is people that use their Z's mostly for racing. I have a 2010 model with only 7K miles. I do not drive my car often but when I do I usually drive it very hard. After the break in period I added an oil cooler and went with redline oil and a bosch filter. Since then when I check my oil I have noticed some metal deposits on the rag when I check my oil. After doing some research I thought that an oil filter magnet might help out.

I believe it falls under the category of "can't hurt" ... but oil filters are already designed to catch anything bigger than 25 micron (half a human hair). It's a little like wearing two condoms imho.

During break-in metal particles are perfectly normal and the use of a magnet won't hurt.

I don't know what variations of the Filter Magnet there is since FilterMag has been pretty much the main brand most use.

Yeah I'd say the same. I use a FilterMag on mine. It's just an extra "can't hurt" insurance, who knows. Maybe it will catch some of the fine ferrous wear on the magnet and free up the filter to flow better for longer, or whatever, but it's probably not a big deal.

I have a magnetic drain plug, I examine the **** out of every time I change the oil. Never seen anything that I thought "whew, glad I got this."

But for $20 (or whatever), I've never been upset I bought it.

Rooskey · 07-18-2012, 01:27 AM

Yea the reason I asked is because this is the first out of many cars that I have owned that everytime I check the oil I have oil and metal deposits on the rag. I believe I will go ahead and change the oil and add the Filtermag to see if it helps out. Hopefully so. Maybe going back to the factory oil and filter may not be a bad idea either.

In case you didn't know, the oil pressure at full throttle is enough to open the bypass valve on the oil filter. So when you are on track your oil is going unfiltered a lot.

wstar · 07-18-2012, 02:33 PM

You have a source on that? I'm not an oil filtration expert, but I don't believe you can generally correlate your oil pressure (as in, gauge reading with an aftermarket PSI gauge) with the relief valve pressure in the oil filter. The relief valve's rated pressure (usually quite low, e.g. the popular KN/Mobil1 for our cars is rated 11-17 PSI) is the pressure *differential* between the input and output sides of the filter, not the absolute pressure you see on your gauge.

DR_ · 07-18-2012, 05:06 PM

A lot of the race oil filters have no bypass or just flow really well (filter less) so they don't bypass. A good street filter doesn't make a good race filter and vice versa.

I guess if you're gonna expect regular engine rebuilds, then sure fine filtration doesn't matter too much

djtodd · 07-20-2012, 11:59 PM

I use filtermag as well. The black version (can't remember the name, standard?) Amazing how strong those magnets are.

Only install tip is, make sure you place it on the bottom of the filter.
