For distributors and trading companies in Southeast Asia, Africa, the Middle East, South America, and Central Asia, multigrade oils like 5W-40 are especially important. The \u201c5W-40\u201d label follows the SAE multigrade system: the \u201c5W\u201d indicates winter (cold-weather) viscosity grade and \u201c40\u201d indicates high-temperature viscosity grade.In practice, this means 5W40 engine oil flows like a SAE 5-weight oil at low temperatures and behaves like a SAE 40-weight oil at high temperatures. This dual rating ensures reliable cold starts and strong protection at operating temperature \u2013 ideal for diverse climates and heavy-duty use. As the Oil-Store technical guide explains, \u201cthe number before the \u2018W\u2019 indicates viscosity\u2026 at low temperatures, and the number after the \u2018W\u2019 denotes viscosi at higher temperatures\u201d.In short, 5W-40 engine oil is formulated to maintain a thicker oil film in hot conditions while still pumping easily when cold, making it a versatile choice for many engines. Difference Between 5W-30 and 5W-40 Engine Oil The primary difference between 5W-30 and 5W-40 lies in their high-temperature viscosity and performance. Both grades share the same low-temperature \u201c5W\u201d rating, so they flow similarly when the engine is cold. However, at operating temperature, 5W-40 has a higher viscosity. Technical data show the kinematic viscosity of 5W-40 oil at 100\u202f\u00b0C is about 12.5\u201316.3\u202fmm\u00b2\/s, whereas 5W-30 is about 9.3\u201312.5\u202fmm\u00b2\/s.In practice this means 5W-40 oil maintains a thicker film when hot. As Oil-Store explains, both oils \u201care grade five when cold, however 5W-30 becomes 30 grade and 5W-40 becomes 40 grade under operating temperatures. In higher temperatures, 5W-40 has higher viscosity levels than 5W-30, which can contribute to uninterrupted engine function\u201d This difference affects engine protection and fuel economy: 5W-30, being lighter at high temperature, flows more easily for fuel efficiency, while 5W-40 provides greater film strength under load.For example, 5W-40 oils have a broader operating range (roughly \u221225\u202f\u00b0C to 35\u202f\u00b0C) compared to 5W-30 (\u221225\u202f\u00b0C to 25\u202f\u00b0C), making 5W-40 better suited to very hot climates or heavy duty use. Conversely, 5W-30 can be slightly better for fuel economy in milder conditions. In summary, is 5W40 thicker than 5W30? Yes \u2013 at high engine temperatures, 5W-40 is significantly more viscous, providing added protection in high-heat scenarios. Choosing 5W30 or 5W40 for High-Mileage Engines For older or high-mileage engines, it is especially important to choose the right oil. Many experts say that 5W-30 is often recommended for engines that have been used a lot because it can flow more easily through parts that are worn. However, 5W-40&#8217;s extra thickness under heat can also help maintain pressure on worn components. Industry analysis shows that &#8220;5W-30 engine oil can be used by many types of vehicles and is especially good for cold temperatures. It is used more often in engines that have been driven more, and it works better in warmer temperatures. In practice, a distributor should check how a vehicle is used: if engines run mainly in stop-and-go traffic or mild climates, 5W-30 may be enough, whereas 5W-40 is better for hot weather or heavy loads. In every case, advise customers to follow OEM guidelines and consider local conditions.\u201dIn practice, what is 5W-40 oil used for? It is the go-to choice for modern gasoline and diesel engines that face hot climates or heavy workloads. Light-duty passenger cars in cold regions might only need 5W-30, but fleets in Africa or the Middle East often switch to 5W-40 during summer. Distributors can highlight that 5W-40 provides a thicker lubricating film under heat, which helps prevent metal-to-metal contact, engine knock, and oil breakdown. It also helps engines maintain oil pressure and performance in cities with stop-start traffic. This makes 5W-40 attractive for taxi fleets, delivery trucks, and other high-mileage applications.
