    Hustler Super Z - Kohler 28 EFI. Engine manual states that you should remove and wipe dipstick then reinsert but do not thread dipstick, only let it rest on top of tube.

    Do you follow this procedure or do you thread dipstick before reading.

    I think Kawasaki rcommends same technique.

    How do you check threaded or unthreaded?

    I've always pushed mine all the way down. For the threaded ones, I've always screwed them down, also. Maybe I've been doing it wrong all these years?

    no--if you thread them in, the oil mark on the stick will read high.

    so if you thread it inand the oil range is normal on the stick, the amount of oil on the crankcase will be low.

    To tell you the truth, I forget how the Kohlers are.

    I do know that my 14hp Kawi does NOT need to be threaded in.

    And my LC Kawi has a regular automotive dipstick.

    If it says to not thread it in, then don't.

    On my Kohler I started checking UNthreaded because that is the PROPER method as outlined by the manual for my 15hp as well. However, before I acquired a manual, I ran the Kohler while checking it THREADED and there is a difference of 1/4 to 1/2 quart of oil between the two methods, the THREADED method will show MORE oil than it should!!! Good thing I run synthetic racing blend oil, you could seize an engine checking the Kohler THREADED as this shows incorrect level and you will run low oil.
    I think the only real other concerns is the engine needs to sit 10-15 minutes on a LEVEL surface withOUT motion, so early morning or after weed-eating might be a good time.
