This represents the oil's resistance to flow at operating temperature (212°F / 100°C). A higher number means a "thicker" oil film, which provides more protection for hard-working or older engines. 2. Performance Categories (The Letters) These ratings tell you if the oil meets

Refined crude oil. Good for basic, older engines with frequent change intervals. A higher number means a "thicker" oil film,
