    TBN: 5.18
    dilution (volatile): 0%


    My concern is the iron but many Analysis from Mobil 1 supersyn shows a lot of iron so for my 10k oci, i dont know what it means or where it came from. Is it because I cleaned my throttle body with a throttle body cleanser and did not flush the oil after that or maybe because I changed my spark plugs after 90000 miles ?!

    I checked on the 18k miles oci from the ls1 pages and if I compare my results from theirs, it's pretty good.

    Any thought, advise?

    Mark.

    About silicon, they only say good on the result, they did not put the result with %.

    LOL

    Its all the chemical products in ppm (particule per milion) in my oil after 10k miles. Fe for example is for iron Al for aluminum etc. lower the better. It also tells the condition of the engine (wearing good or not, sludge etc).

    Mine says the engine is looking good, no sludge etc. I think the OLM does it job but my concern is the iron even though its not that high!
