The great oil debate 1 year ago

Anyone familiar with Subarus knows oil is a fiercely debated topic, but with that being said, you'll see this oil recommended more than any other... for good reason! Don't run anything else in your car! Your engine will thank you!!

I like the quality of the Motul oil. The type I'm using is designed for smaller engines that are boosted.makes sense to me

  • Q: Motul 5w40  Zbradlie85011 months ago

    How does 5w40 compare to 5w40? Would it do harm to my 2015 WRX to put 5w40 in it over 5w30?
    • 0 of 0 people found the following answer helpful

      A:  It could possibly harm your engine as it is a thicker oil. If Subaru recommends 5W30, that is what you should use.
