My Honda manual recommends:
above 50Â°F / 10Â°C - SAE 30
above 0Â°F / -15Â°C - SAE 10W30
below 30Â°F / 0Â°C - SAE 5W30
Oil is a major factor affecting performance and service life. Use 4-stroke automotive detergent oil.
SAE 10W30 is recommended for general use. Other viscosities shown on the chart may be used when the average termperature in your area is within the recommended range.
The SAE oil viscosity and service classification are in the API label on the oil container. Honda recommends that you use API SERVICE category SF or SG oil.
Regarding oil filters, many people feel that Fram filters are below the quality of Wix or Purolator. For more information about oil and filtration, visit Bob is the Oil Guy
