Mpg but it did in fact.
Okay, couple of things. First of all, does your ISP charge you extra for using punctuation? Like is there a money saving thing going on with the absolute lack punctuation?
The reason I ask is because if I was to ask a question that I wanted people to help me with, I would want to express it in a way that's easy for them to understand so that I could get a helpful/correct answer from them. However, I feel your writing style of no punctuation, and comments flowing into one another without transition, makes it difficult to understand.
As for your comments, how do you know the stock Subaru oil was breaking down? How do you know that Royal Purple was breaking down and leaving the internals dirty?
Changing your oil every 1,600-1,800 miles is overkill. It doesn't protect your oil any better, it wastes your time, and it wastes your money. Even Subaru doesn't suggest changing your oil under 3,750, so you can safely double your OCI.
Using a quality Xw-30 or Xw-40 oil will protect your engine and turbo, and ensure you don't have an oil related issue for a long time; (gasket leaks are not a motor oil issue, they're a known occurrence on Subarus).
