S80 2.9 Oil Capacity S80

OK This seems to be an easy one but I have a question. The owners manual shows 7.3 US quarts with a filter for the oil capacity. I change my own oil with the car jacked from the front on jack stands. I put 7 US quarts and a new filter and the car checks slightly over the top "Max" mark on the stick. The owners manual reports the marks to be "Min" and "Max". I had a Ford Expedition with the "Min" and Max marks and a capacity of 6 qts with filter. It took 7 to reach what I referred to as full but they call "Max". 6 would put it in the middle. The Ford Dealer said that 7 would make vibrations in the engine from oil to crank spash and the vehicle should be in the middle between "Min" and "Max".

This leads me to my question. A Volvo Dealer changed the oil for me only one time when it was required to write a Volvo VIP Warranty on the vehicle. I checked it after they changed it and it was between Min and Max about 75% of the way and off the Max. I topped of to the Max mark. Where should it be on the stick? If 7 qts puts it slightly over "Max" should it be 6 or 6.3 qts with filter. If there is a Volvo Tech out there I would appreciate a response. Thank you in advance. I did not want to ask the Dealer due to I perform all of my own service and document with receipts for the warranty and I did not want to come off as someone that cannot even read an owners manual much less change there own oil when I have a valid question. I long for the simple days of "ADD" and "Full". I know for a fact that Ford changed the way we look at dipsticks, did (Ford owned) Volvo?

    This question comes up here on occasion and you asked for a techs opinion so I'll give you mine. I don't care what any manual says, when you're in the auto business and you do an oil change, after the oil and filter is changed the oil level has to read FULL on the dipstick after sitting or the customer who then double checks your work will accuse you of short changing him, right?

    ATF does expand with heat so an auto trans is best checked with its ATF hot (normal op temp) but I've not known that to be true with engine oil in my experience.

    One should check oil level after it sits for a while so that all the oil has drained down, not right after running the engine.

    Ford researched how and when customers checked their oil and they found out that they check it at the gas station with the engine warm.
    so, as a result of these findings the engine oil dipstick is calibrated to give an accurate reading only when the engine and the oil are at normal operating temperature.

    Because engine oil and transmission oil expand when they are warm ,it would not be entirely accurate to check the oil when the engine is cold. (not if your checking to see if you are at "Max fill") because it may read in the "add" zone when it is cold but show "Max Fill" when the oil is warm and fully expanded.

    so, check your oil when your engine is at it's normal operating temperature. same goes for Transmission fluid.
