    well all was just wondering What 5w30 synthetic oil do you use. (Royal Purple, Amsoil etc)

    saw this video and looked pretty interesting about Royal purple oil

    Just want a heads up on what works best for Subaru.

    in the beginning he does 5w30 Amsoil and about 13:10 he starts the Royal Purple test for 5w30

    Forget about Royal Purple. Stick with your favorite 5W-30 Synthetic that gives you good UOA results.

    Some will also swear by Rotella based on UOA results and internet recommendations, but there's debate on whether it meets Subaru requirements for warranty consideration.

    The test in the video is irrelevant. Data from your motor would be relevant. I'd not use RP or Amsoil. Find something locally that meets SOA spec and gives you good UOA data.

    Man, if only there were previous threads about this topic that had been created and this site had a search function to find them. I think you should message the creator of the site so you can get this search feature added.

    The test is flawed and biased! He drops the weights when using Amsoil, and gently lays the weights when using Royal Purple.

    I've debated on what oil to use myself. Yes, I would like to use the "best" possible to protect my car. However, I dont see a real way of determining that other than constantly changing to different oils and having them tested.

    I feel that a lot of the "differences" in these oils are just marketing. Yes, some may be better or can out last other oils. But no matter how long an oil can last, the oil filter can only go so long as well, defeating the purpose of going longer intervals. Yea, you could change the filter alone. But why not change the oil as well? Then you know you are protected.

    Just get a good oil that meets specs, and keep it changed. I personally change mine more often than necessary, but you can never change it to much. The contrary, however, could definitely shorten your engine life.
