I just purchased a Carbon Cub SS with the X340 engine and am getting conflicting info on how much oil to add with a oil change and when to add oil. I see every thing from 4.5 Qts on a oil change to 5 Qts and 6 Qts and to add at 3.5 qts and to add 1 qt when it gets to 4.5 qts. My dip stick has mutiple marks on it and that may be because of the attitude of the plane from having 6.00X6 tires up to the 35" tires it has now. I have also read that the filter and the lines hold one qt of oil and I need to know if that all drains back into the sump when left sitting. I need to drain all oil and start adding oil to mark the dip stick correctly. Previous owner did not even know.
