High-Temperature Stability Conversely, the demands of summer driving and high-speed highway cruising present the opposite challenge. At lower temperatures, the first number in the grade (e.
Exploring Additives and Future Trends in Multigrade Motor Oil
For drivers who frequently tow heavy loads or operate in consistently hot environments, a 15W-40 or 10W-40 might provide superior high-temperature stability. Multigrade motor oil represents one of the most significant advancements in lubricant technology for modern engines.
Cold Weather Performance One of the most noticeable advantages of using a multigrade formulation is the elimination of the "cold wax" problem associated with single-grade oils. When temperatures drop, standard oils can become so viscous that they struggle to reach critical components, leading to dry starts and accelerated metal-on-metal contact.
Exploring Additives and Future Trends in Multigrade Motor Oil Technology
While the owner’s manual provides the optimal recommendation—such as 5W-20 or 10W-40—drivers must consider their climate and usage. Furthermore, the reduced friction compared to older monograde oils directly translates to better fuel economy and lower carbon emissions over the life of the vehicle.
