Have about a gallon too much oil in the 8v92. Don't ask how that happened.
     Which is more dangerous - ignoring it, or climbing underneath and loosening the oil filter to drain off the excess?
     Thanks for the usual fine suggestions!

   Mike, do you have (or can you borrow from a friend) a vacuum oil extractor like this?  I bought it because it works really well on my VW diesel Jetta but after I owned it, I found that it was useful for many things.  (PS  This is way overpriced but I wanted a photo and it was the first one on Google.)

Since the oil in the pan is not under any pressure, it is easy to loosen the drain plug and let a gallon out.  If you should happen to loosen it too much and the plug comes out, you can just screw it back in. When I bought my Fumato drain valve, it installed it just that way with barely a cup of spillage, and 40 weight oil is a wonderful moisturizer.

Too bad that you don't have a Fumoto drain valve in place of the pan plug, easy to drain any amount out without needing a wrench or making a mess.  Grin

Yes, Fumotos are great.   They make jobs like this a breeze.   Just make sure it would not be the lowest thing above the ground!   Otherwise, hand-cranked transfer pumps are good for moving liquids, and there are also drill-powered versions that are quicker.

Thanks everyone.
     Spent the middle afternoon under the bus, and the idea of loosening the oil drain plug worked great - didn't even drop it.
    Took a gallon out, and the oil dipstick is now on the money.
    Being the tightwad that I am, I even captured the barely used oil for use in topping off the crankcase in the year to come.     
    The idea of a Fumoto drain valve is interesting.
Thanks again.

 Another tip:: always check the oil after sitting overnite,,if you check it too soon after a run you will be "chasing" 1/2 gallon and be overfull..>>>Dan

4104 and 4107 manuals say to check the oil after sitting a few minutes after being driven.

I like the steel plug with the magnet too.  Old school, but I like seeing what sticks to the magnet.
