    Default AC Delco oil filter indentification

    Hey

    I purchased a new AC Delco oil filter and on the bottom of the filter there are some numbers and letters. Is this a date code?
    It reads AC 09070Q 15:32.

    Thanks

    My guess is that it may be a lot number and a time of production.

    09 may be 2009
    070 may be 10 March. 070 being a Julian date. 10 March is the 70th day of a non-leap year
    Q might be the plant where it was produced or a batch number

    just curious, why are you concerned with these numbers.
    everything has some sort of code on it
