I can't really help out with your math not knowing which filter [new or old] you have in your car. That entire oil filter housing is full of oil until you start to loosen the cap [which you will then begin to hear oil draining out].

When I performed my oil change I swapped out my filter and put in 8 quarts and fired up the car to get the filter filled with oil. I let it set for a while and checked the level then on the dipstick. All was good. I wonder if the first paper oil filters [which mine had] held more oil in them vs the newest fleece filters, which would explain why we should only put 8 quarts in now vs the 8.5??? I say this because the original paper filter had quite a different construction [somewhat bulkier] that the newest fleece filter. I quadruple verified that I did indeed have the correct filter too.
