The 2008 Honda Fit requires 5W-20 engine oil that meets API SN or newer standards. You can use conventional or synthetic oil, and the engine typically holds about 3.7 quarts with a filter. Always confirm the exact specification in the owner’s manual or on the under-hood label for your vehicle and region.
Official specification
The 2008 Fit’s 1.5-liter engine is designed to run on lightweight oil to support efficiency. Honda’s factory guidance calls for 5W-20 motor oil that meets API SN or newer specifications. This viscosity is compatible with both conventional and synthetic lubricants. The oil capacity with a filter change is approximately 3.7 quarts (about 3.5–3.8 liters), depending on the exact model and regional variations.
Choosing between conventional and synthetic
Both conventional and synthetic oils that meet the API SN or newer standards are acceptable for the 2008 Fit. Synthetic oils tend to offer better high-temperature stability and longer change intervals, which can be advantageous for drivers who put extra miles on the car or operate in extreme conditions. If you follow Honda’s maintenance minder and service schedule, either option can work well, so the choice often comes down to personal preference, cost, and driving conditions.
Climate and driving considerations
For everyday driving in temperate climates, 5W-20 remains the standard. In very hot climates or for heavy-duty use, some owners opt for premium synthetic options to enhance protection, but it should still be 5W-20 and meet API SN or newer. Always avoid using a viscosity outside the recommended range unless directed by a qualified technician.
Where to confirm the exact spec
The definitive source is the owner’s manual, which lists the recommended oil viscosity, the required API specification, and the oil capacity. A label under the hood may also specify these numbers. If you don’t have the manual, a Honda dealership or a trusted automotive technician can verify the recommended oil for your vehicle’s year and market.
Summary
For a 2008 Honda Fit, use 5W-20 engine oil that meets API SN or newer standards. Both conventional and synthetic oils are acceptable, and the typical oil quantity with a filter change is about 3.7 quarts. Always refer to the owner’s manual or a dealer for the exact specification for your vehicle and region.
