I've looked in the owner's manual, maintenance and warranty manual and online but no luck -- the manual only mentions the 3.0 and 3.6. I found somewhere that the initial oil change takes place at 7,500 miles or 7.5 months but no clue how frequently after that.
No guesstimates please and provide your source if possible.How often do I have to change the oil for a 2010 Subaru Legacy 2.5i?many vehicle manufacturers are extending their recommended service intervals to 5,000 or 7500 miles these days, but as a prfessional mechanic I still recommend an oil change every 3000 miles or 3 months on ALL makes and models. These extended service intervals are used as a selling point on new models, and I have not yet seen any evidence that the vehicles are actually equipped to handle this over thier lifetime of use. Also, if you check the manufacturer service schedule you will notice it differs based on wheter you fall under the %26quot;normal%26quot; or %26quot;severe%26quot; driveing categories. The %26quot;normal%26quot; category is generally reserved for people who almost never drive their car and 80-90 percent of actual vehicle owners fall under the %26quot;severe%26quot; driving schedule, which generally still is a recommended 3000 mile or 3 month service interval.How often do I have to change the oil for a 2010 Subaru Legacy 2.5i?Your best source for that information is your Owner Manual but the Edmunds maintenance guide will also have the manufacturer's recommended maintenance schedule (use the drop-down menu to select your year, make, model, engine, etc):
