Xiaohai, 2 years and 4 months old, wants to change the gearbox oil and directional oil (for help, there are car changing friends) _ Haifuxing Automobile.

(Semi-synthetic) engine oil can be changed around 5000 ~ (fully synthetic) and 8~9000 ~ (fully synthetic). luggage case Power will be good. If you don't believe me, try it ~ ~ The brake oil has been changed. Look at the brake oil yourself. Needless to say, when you see the black one (Dot4, please make it clear when you change it. The black shop will give you DOT3. I'm not afraid (4L is not enough, I'll add some water). 30,000 kilometers changed the gearbox oil, but I didn't expect the new car to be changed in 3 kilometers. I didn't even think of that. It looks like mud, and I don't think what the manufacturer gave me is a good thing, so I changed it at 2W km now, and the gear shift is much smoother (1.6 hands, oil change 1L direction is just right) ~ ~ I can find a friend with automatic transmission. () I haven't changed the gas filter ~ I only changed it when the car ran out of gas ~ ~ I'm not a good person. My friend is a car dealer. It's boring for me to sit in his shop and learn some fur, so I'll study it for you ~!
