I do have a siphon pump, shall i use it to remove a quart of oil ?
How long has the oil been in there ?
If its nearly due for a change; just change it early and fill to the correct level.
If the oil has has several months of life to go,just change the oil filter but don't top up, that should bring the oil level down by 0.5L or so.
If the vehicle comsumes oil it will bring it down slowly, if your vehicle doesn't consume oil you better attend to immediately.
The 1 quart overfull I have never across, I guess there is some freeboard allownace for topping up, but I would not go over by more than 0.5 quart.
