How much oil does a Honda Civic Si 1.5 take?
Approximately 3.7 quarts (3.5 liters) of engine oil, including a new filter, for a standard drain-and-fill on the Civic Si’s 1.5-liter turbo engine. If you drain only and do not replace the filter, the oil volume needed can be about 3.4 quarts (around 3.2 liters).
Official capacity and year-to-year variation
The Civic Si uses a turbocharged 1.5-liter engine. Oil capacity is specified by year and market, but most U.S.-market manuals list roughly 3.7 quarts with the filter. Use the official owner's manual or under-hood specification label for your exact year to be precise.
Typical oil grade and viscosity
Honda generally recommends a synthetic oil of 0W-20 for this engine in most climates. Confirm the exact specification in your owner's manual, as some regional configurations may vary.
Oil change guidelines and steps
For a DIY oil change, follow these steps to ensure you replace the oil and filter correctly. The specific quantity you add should reflect the capacity noted above.
- Warm the engine to operating temperature to maximize drainage.
- Safely lift and support the vehicle if needed, and place a drain pan beneath the oil pan.
- Remove the drain plug and allow the old oil to drain completely.
- Remove and replace the oil filter, lubricating the new filter seal with a bit of fresh oil.
- Reinstall the drain plug and pour in the recommended amount of new oil (about 3.7 quarts with filter).
- Check the oil level with the dipstick and top up in small increments until the level is at the full mark.
- Start the engine, run briefly, then recheck for leaks and confirm the oil level again after a short idle.
In short, plan for about 3.7 quarts (3.5 liters) of oil with a new filter for a Civic Si 1.5, while noting that exact figures can vary by year. Always follow Honda’s official specs for your model year.
Summary
The Honda Civic Si powered by the 1.5-liter turbo generally requires around 3.7 quarts (3.5 liters) of engine oil when performing an oil change with a new filter. Verify the precise capacity for your model year in the owner's manual or service bulletin, and use the recommended oil grade (typically 0W-20 synthetic). Following the proper procedure ensures optimal lubrication and engine longevity.
