Wait.

Don't replace it with synthetic if its your first oil change!!!


Wait to around 5-6,000 miles before switching to synthetic

I think Subaru recommends waiting 'till the break-in period is over...That's all.

The engine needs the friction that crappy oil provides to properly wear in.

I sent an email to Subaru at mysubaru.com concerning the use of synthetic oil. Here is the response below. Take for what it's worth.


Thank you for contacting the Subaru Web site, and congratulations on the purchase of your '02 Impreza WRX! We hope that you are enjoying this exciting model!

As for synthetic oil, this is your decision. Our Technical Services Department advised that if you do decide to use synthetic oil, that you always use it because your engine will become accustomed to it. The same goes if you decide to use 'regular' oil.

We recommend that you first change the oil in your WRX at 3,000 miles or 3 months, whichever comes first. We STRONGLY recommend that you at least wait until the break-in period of 1,000 miles is surpassed.

The break-in period of the engine requires that a given amount of friction exists between components. The piston rings need to rub against the cylinder wall to break-in or finely tune the machine mating between the two metal parts. To properly seat all mechanical components, a certain amount of friction is required between the metal parts. Since synthetic oil has a lower friction rating than regular oil, we recommend that Subaru owners wait until after the 1,000 mile break-in period to switch to synthetic engine oil.

Synthetic engine oils can be used in our engines if the user follows the engine oil recommendations prescribed in the Owner's Manual. Subaru has not tested the compatibility of all synthetic oils with engine seals, but the petroleum industry does adhere to standards for the refining process which meet Subaru requirements. Subaru does not guarantee the performance of any brand of any engine oil.

Engine Oil Guidelines: - only use engine oil that meets or exceeds the API classification designated in the Owner's Manual for the vehicle - only use engine oil that meets the VISCOSITY requirements for the ambient temperatures under which the vehicle will be operated as outlined in the Owner's Manual - THE ENGINE OIL MUST BE CHANGED AT THE INTERVALS SPECIFIED IN THE WARRANTY AND MAINTENANCE BOOKLET FOR THE VEHICLE. SOME SYNTHETIC OIL REFINERS RECOMMEND EXTENDED OIL CHANGE INTERVALS. SUBARU DOES NOT RECOMMEND ANY DEVIATION FROM THE SPECIFIED INTERVALS IN THE OWNER'S MANUAL.

Thank you for the opportunity to be of assistance.
