Never assume a number based on a similar-looking vehicle, as even minor design differences can alter the requirement substantially. Typically, the drain capacity is slightly less than the total because the new filter and engine components retain a small amount of oil, known as residual oil.
Then, remove the dipstick, wipe it clean, reinsert it fully, and pull it out again. If it is low, add oil incrementally; if it is overfilled, you must drain the excess immediately.
