I have a YD25 2008 4x4 model takes 5.5lts about 2mm below the full line. The manual says 4lts but it doesn't even register on the dipstick, ive done 6 or 7 oil changes and every time i use 5.5lts.
Sometimes i takes the oil a while to get to all the small places. So i dump 5lts in wait for 10mins, take it for a spin, let the engine cool, check the level again and add if needed.
