What does SAE 40 mean?

SAE 40 is a monograde oil designed for engines operating in higher temperature environments or under heavy load conditions:

• SAE 40: offers a stable lubricating film, ensuring smooth engine operation in environments where temperature fluctuations are minimal. Its formulation helps reduce engine deposits and maintain cleanliness over time.

What is SAE 40 oil used for?

SAE 40 is commonly used in older vehicles, diesel engines, and industrial machinery that operate in hot climates. Its thicker consistency offers excellent protection for engines working under high loads and in warm conditions. However, it is less effective in cold temperatures, where thinner oils are preferred for easier cold starts.

What is equivalent to SAE 40 oil?

• SAE 15W-40 oil: frequently used as an alternative due to its multi-grade properties, providing excellent protection in a variety of temperatures.
• SAE 10W-40 oil: ensures good performance in colder weather, with similar high-temperature viscosity as SAE 40 oil.
• SAE 20W-50 oil: suitable for engines requiring thicker oil at higher operating temperatures, offering a slightly broader range of protection.
