    Check out THIS link which shows some example analysis reports and their associated explanation.

    Generally speaking, I'm looking for these things in an oil analysis:

    1) Is there antifreeze, fuel or water in the oil?
    2) Is there dirt in the oil?
    3) Are there unusual levels of any specific metals in the oil?
    ah .. ok.. I stand corrected. I have not taken notice of that. So, I zoomed out the pic.. haha.. Thanks for pointing out.

    [QUOTE=Mitz;60917][I]So how do we translate the report and put it to good use? I'm thinking of putting a FilterMag if it would help.[/I/QUOTE]


    Be careful. Magnets put on the outside of a filter (or sump) probably do absolutely nothing. The steel conducts the magnetic flux so none of it actually penetrates into the oil. Do a quick check. Get a magnet and a piece of steel that's 10 or 20 times the diameter of the magnet. Sprinkle iron filings on the side opposite the magnet and see how many actually stick. Probably none. Magnets in drain plugs make more sense. I've seen the oil filter magnets called everything from 'snake oil' to 'outright fraud'.

    Plus magnets loose a bit of their magnetic strength the hotter they get, and on top of that the only metal they may help with is Iron, as that's the only magnetic metal in the engine. Anything the magnet could hold onto will be caught by the filter anyway. All of the oil analysis I have seen for our cars do not show significant Iron wear and I beat on mine for 15,000 miles....so the magnet is a waste.

    Based on previous oil analysis of our engine I would say just watch aluminum, TBN, fuel, coolant, and silica and you will be good. Our engines might not be the lowest wearing (per mile) out there, but they are proving to be quite durable.

    It appears FilterMag's claims are legit

    http://www.shopfiltermag.com/how-it-works/
    http://www.shopfiltermag.com/results2/

    While it may be hard to justify, I do not consider it (FilterMag) as a fraud, and just wondering how those residues cling unto the can's wall while there is none on the cans w/o the magnets.

    To add,
    Iron is ferromagnetic material while aluminum is paramagnetic.

    Well, that is the manufacturer's claim...

    Any engine giving off that much iron or steel particles has some big problems!

    That being said, I certainly don't see the harm in using a magnet, and I'm sure it will have at least a positive effect on the engine, despite the negative effect on the wallet.

    Wouldn't a magnet user want the magnet located on the bottom of the filter instead of the top?

    Who knows - I doubt I'd ever get one (kinda pricey for what it is.)

    Or, you could just buy your own magnets: Amazon: neodymium bar magnet

    But what would it hurt to stick a magnet on the can?

    This bothered me all night. This morning I got an empty can, a magnet and a spoon. I stuck the magnet on the outside of the can and stuck the Spoon inside. The magnet actually attracted the spoon through the can.

    I am properly ashamed of myself.

    Here's my latest 5,000 mile oil analysis. My Mirage now has 30,000 miles on it. I continue to use Mobil-1 Extended Performance 5W30 oil with a Mobil-1 M1-110 filter and change them at 5,000 mile intervals.

    Remember that I'm doing this every 5,000 miles just to establish a solid pattern of oil analysis results for our cars.

    Don't forget that the most recent numbers are on the left side of the page.

    With the wear doing so well, and more than sufficient TBN, do you plan on extending your change intervals?

    The most I would do at this pont is to go out to the 7,500 interval specified in the service manual. But I probably will keep changing it every 5,000 just because I'm a little OCD. Plus I like rotating my tires every 5,000 miles...so I just do everything at the same time when the car is up on the lift.

    Any reason you've decided to run 5w30 instead of the suggested 0w20?
