Recommended by the manufacturer. In minus 20 gears switch perfectly. Check the manual transmission breather. It is necessary to remove the engine air filter, directly under it. Looks like a thimble. Remove carefully by swinging the pliers to the side. Under it is a spring and an elastic band. See that the spring does not fly away. The rubber band that covers the hole and releases vapors, sticks. Excessive pressure does not bleed and the oil begins to squeeze out. So you need to control the condition of the breather.
