Question 2

How often should I change this oil?

Accepted Answer

Always follow the oil change interval recommended by your vehicle's manufacturer. Factors like driving conditions, towing, and engine modifications can affect how often you need to change your oil.

Question 3

Accepted Answer

While CK-4 oils are designed for modern diesels, they are often backward-compatible with older engines. However, always consult your vehicle's manual or the oil manufacturer's recommendations to ensure compatibility.
