    Question 2011 WRX - 1st Oil Change 3750 vs. 7500 miles

    I am coming up on 3750 miles and have been debating whether or not to perform the 1st oil change @3750 or @7500 miles. Manual says 7500, many forums recommend 3750. For other cars I have owned, the manufacturer claims that a special high quality oil is used for break in puposes and not to change until the recommended interval. I don't know what Subaru does.

    Any advice is much appreciated, thanks!

    Dealership I worked at recommended 3,750. I change my own only at 1,000 miles with a new motor personally.

    3750 at the latest I would go considering the car comes with 5w-30 energy conserving oil. I did the first change at 1000 miles too just for a piece of mind. I know they recently changed the intervals to 7500 miles but if you read the entire article it still says to change at 3750 under severe conditions or even sooner under race conditions. 7500 is under "normal" conditions which is no short trips (less than 10 miles) and driving like an old lady.

    Agreed with 3750 at the very latest on a new motor. I'm coming up on 2700 at the moment and I'm already upset I didn't do it sooner. Just made my appointment thanks to this thread

    Yeah thats what people dont get.. "normal" to a mfr means "optimal" conditions.. not the actual conditions we drive in. Which by thier standards would easily be "severe" at best.

    I changed mine at ~2000 miles, then again at ~3850 miles. From now on, I plan on using the interval specified in the manual.

    I got my first one done at 3k via subaru.

    If it wasn't the dead middle of winter and sub-freezing temps out, I would have done the first one at 1k miles.

    3750 for turbo engines, 7500 for the NA flavor. I do 3500, easier to remember.

    I did my first change at 2872 miles with dino oil, then switched to Mobil 1 5W-30 at 6592. 58k+ miles later all seems great with no discernible oil consumption.
