The 2004 Subaru Impreza uses SAE 5w-30 viscosity, fully synthetic motor oil to keep its engine running. IT has an oil capacity of 4.8 quarts. You can expect to pay between $2 and $34 per one-quart bottle, found at most automotive retail locations, and from some online sellers. To change the oil, You will need to first drain the d***y, old oil from the bottom portion of the reservoir via the drain valve nozzle. If You choose to have it replaced by a professional mechanic or service technician, You can expect to pay between $30 and $132 for labor. Remove the plastic cap from the top of the reservoir, then using a funnel, pour the fresh fluid into the tank, until it reaches the max fill line.
