Viscosity is how thick the oil is. It’s shown by numbers like 15W-40. This tells you how the oil flows when it’s cold and when it’s hot. Your engine manual will tell you the right viscosity for your vehicle.
3. API Service Category
The American Petroleum Institute (API) gives oils a category. This shows what kind of engines the oil is good for. For diesel engines, look for categories like CK-4 or FA-4. These are designed for modern diesel engines.
