Most modern Honda cars use 0W-20 synthetic oil, but the exact grade depends on the engine, year and climate. This article explains typical requirements for Honda automobiles and motorcycles and how to determine the correct oil for your vehicle.
Honda cars: typical oil viscosity and specifications
For most newer Honda cars, the recommended viscosity is 0W-20, and synthetic or synthetic-blend oil is common. Some older models or certain engines in warmer climates may specify 5W-20 or 5W-30. Regardless of viscosity, use oil that meets API SN or newer and ILSAC GF-6 (or GF-5) ratings, with Honda’s own Genuine Motor Oil or an equivalent that meets these specs. Always verify the exact requirement in the owner’s manual or with a dealership.
Common oil choices you will encounter in Honda car owners manuals:
- 0W-20 synthetic oil is the standard recommendation for most contemporary Honda engines, offering good cold-start protection and fuel efficiency. Look for oils that meet API SN or newer and ILSAC GF-6 (or GF-5) ratings.
- 5W-20 or 5W-30 may be specified for older engines, special applications, or certain climates; always confirm the grade specified for your specific vehicle.
In addition to viscosity, the oil should be API-certified and meet ILSAC GF-6 or newer. Honda recommends using Honda Genuine Motor Oil or a high-quality equivalent that meets the specified standards. Using the wrong grade can affect engine protection and may impact warranty coverage.
Where to look in the manual
Check the owner’s manual or service guide under the Maintenance or Specifications sections for the exact viscosity and API/GF rating required for your model. If you’re unsure, contact a Honda dealer or qualified mechanic to confirm before an oil change.
Honda motorcycles: engine oil basics
Honda motorcycles use four-stroke motorcycle oil that meets JASO MA or MA2 ratings and API SN or newer. Viscosity is typically around 10W-40 for many models, though some bikes may use 10W-30 or 5W-40 depending on engine design and climate. Always confirm the exact specification and change interval in the motorcycle’s owner manual.
Common guidelines for Honda bikes:
- 10W-40 motorcycle oil that meets JASO MA/MA2 and API SN or newer is typical for many four-stroke Honda motorcycles.
- In cooler climates or for certain engines, 10W-30 or 5W-40 may be recommended; check the manual for your specific model.
Motorcycle oil serves both the engine and, in many models, the transmission/clutch system, so using the correct oil type and viscosity is essential for performance and longevity. Follow Honda’s recommendations and choose an oil that aligns with the specified JASO and API ratings.
Where to find bike-specific specs
Consult the motorcycle owner’s manual or the official Honda service portal for the exact oil grade, JASO rating, and change intervals for your model. If in doubt, a licensed Honda technician can verify the proper oil and ensure proper clutch operation and performance.
How to confirm the right oil for your Honda
The oil grade you need is specified in your vehicle’s owner’s manual. If you don’t have the manual handy, contact a Honda dealer or a trusted service shop. As a rule of thumb for modern cars, many Honda models require 0W-20 synthetic oil that meets API SN or newer and ILSAC GF-6 or newer; for motorcycles, use 10W-40 motorcycle oil that meets JASO MA/MA2 and API SN or newer. Always verify the exact specification for your model.
Summary
In short, Honda’s current guidance centers on 0W-20 synthetic oil for most modern cars, with exceptions for older engines or specific climate conditions where 5W-20 or 5W-30 might be specified. For motorcycles, use a 4-stroke motorcycle oil that meets JASO MA/MA2 and API SN or newer, commonly around 10W-40. The key is to check your owner's manual or consult a Honda dealer to ensure you use the exact grade, rating, and change interval recommended for your vehicle.
