How to Change the Oil on My 2004 Civic Si
Honda released the Civic for the 1973 model year and the first Si trim level appeared on the 1985 Civic CRX. In 1986, Honda released a Si version of the Civic hatchback. The 2004 Civic also came with a Si trim level. This high-performance economy car came only as a two-door hatchback and Honda fitted it with a 160-horsepower, 2.0-liter four-cylinder engine. Honda recommended replacing the engine oil and filter in the 2004 Civic Si every 10,000 miles.

Insert the funnel into an empty oil bottle and fill it with old oil from the drain pan. Close the bottle.

Many auto parts stores take old oil and filters free of charge.
