5W-20 oil is another multi-viscosity oil suitable for a wide range of Toyota Corollas. The “5W” indicates that it flows slightly less easily at low temperatures compared to 0W-20, but still provides adequate cold-start protection. The “20” indicates its viscosity at high temperatures, which is the same as 0W-20. 5W-20 is often recommended for Corollas operating in moderate climates where extremely cold temperatures are not a frequent concern.
5W-20 offers a good balance between fuel efficiency and engine protection. It provides slightly better protection at higher temperatures compared to 0W-20, making it a suitable choice for drivers who frequently engage in demanding driving conditions, such as towing or heavy acceleration.
5W-30: A Thicker Option for Older Engines or Hot Climates
5W-30 oil is a slightly thicker multi-viscosity oil compared to 0W-20 and 5W-20. The “5W” indicates its low-temperature viscosity, while the “30” indicates its higher viscosity at high temperatures. Some older Corolla models or those operating in consistently hot climates may benefit from using 5W-30.
The higher viscosity of 5W-30 can provide better protection for older engines with worn components, helping to reduce oil consumption and maintain oil pressure. It also offers enhanced protection in hot climates, where thinner oils may not provide adequate lubrication. However, using 5W-30 in an engine designed for a thinner oil like 0W-20 can potentially reduce fuel efficiency. Always consult your owner’s manual before switching to a different viscosity grade.
