* Recommended by Honda: Honda's official service manuals specify SAE 10W-30 as the recommended oil for this model.
* Multi-grade: The 10W-30 designation means it's a multi-grade oil, providing good viscosity for both cold starts and high temperatures.
* Engine Type: The Big Red's engine is designed to work well with a mid-grade oil like 10W-30.
Important Considerations:
* API Rating: Make sure the oil you choose meets the American Petroleum Institute (API) rating for your engine. Older engines may require an API rating of "SF" or "SG".
* Quality: Choose a high-quality oil from a reputable brand.
* Change Intervals: Follow the manufacturer's recommended oil change intervals. For your 1989 Big Red, this is typically every 50 hours of operation.
* Environmental Conditions: In extremely cold climates, you might consider using a 5W-30 oil for easier cold starts.
Always refer to your owner's manual for the most accurate and up-to-date information.
