REMARK
When the ambient temperature is low, water or emulsified matter may stick to the dipstick, oil filler cap, etc. or
the drained oil may be milky white because of water vapor in the blowby gas. However, if the coolant level is
normal, it is not a problem.
There is no problem even if the emulsified matter cannot be removed completely after changing oil.
