SERVICE INFORMATION
Theres a new performance standard for engine oil: GF-4. It was jointly developed by automotive and oil experts, and it represents a significant performance upgrade and improvement in fuel economy. GF-4 engine oils must pass grueling tests totaling over 500 hours. On top of this, Honda Genuine engine oils are also tested to ensure specific compatibility with Honda vehicles.
GF-4 engine oil is compatible with all current and earlier model year Honda cars and trucks. It also provides these added benefits:
- Improved oxidation resistance (reduced thickening of the oil)
- Improved deposit protection and better wear protection
- Better low-temperature performance over the life of the oil
- Environmental protection by extending the life of emissions systems
While Honda has upgraded its engine oil to GF-4, other brands may not yet be at this new standard. Keep in mind you must use Honda Genuine engine oil for all warranty repairs. If you use some other brand of oil for non-warranty repairs, make sure that oil meets the GF-4 standard. We recommend you stop using non-GF-4 engine oils and check with your supplier that youre purchasing GF-4 oil.
Engine oil produced after April 1, 2005, that meets the GF-4 standard, must post this starburst certification mark on the container:
Always look for this mark; some oil container labels won't specifically refer to GF-4.
