What grade of engine oil is suitable for the Odyssey?
2 Answers
Odyssey uses 5W40 and 0W20 grades of engine oil. Different viscosity grades of lubricating oil should be selected based on varying environmental temperatures and vehicle conditions. It is best to use multi-grade oil, which is suitable for all seasons. Below is an introduction to the types of automotive engine oil: 1. High-temperature type (such as SAE20-SAE50): The number indicates the viscosity at 100 degrees; the higher the number, the higher the viscosity. 2. Low-temperature type (such as SAEOW-SAE25W): W indicates that it is only for winter use; the smaller the number, the lower the viscosity and the better the low-temperature fluidity. 3. All-weather type (such as SAE15W/40, 10W/40, 5W/50): Indicates that the viscosity grade at low temperatures meets the requirements of SAE15W, 10W, and 5W respectively, and the viscosity grade at high temperatures meets the requirements of SAE40 and 50 respectively, making it suitable for both winter and summer use.
I've been driving an Odyssey for over a decade, always using 0W-20 oil, which is a full synthetic type and particularly effective at protecting the engine. I remember one winter when the car had trouble starting in the cold; after switching to 0W-20, morning starts became much smoother due to its better fluidity. Honda recommends this viscosity primarily for fuel economy and to extend engine life. When choosing oil, consider seasonal changes—you can use 5W-20 in summer instead, but avoid randomly switching to higher viscosities. Additionally, change the oil every 5,000 kilometers or six months to prevent sludge buildup. Using the wrong viscosity, like oil that's too thick, can accelerate engine wear and spike fuel consumption. It's best to stick with reputable brands like Shell or Mobil to ensure reliable quality—never skimp on cost. Overall, the Odyssey is quite particular about oil, so just follow the manual.
