Subarus have more trouble than many engines with staying clean internally, which is a significant factor in why so many use so much oil.

When you want to extend the life of your high mileage engine and emission system, there is no better choice than Castrol GTX High Mileage Motor Oil. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average.

Castrol EDGE, an advanced full synthetic 10W-30 motor oil, is Castrol’s strongest oil and a great option for those who want the very best for their car.There is an averaged out survey done by a BMW forum of UOA results for a 5K mile OCI that compares different synthetics and non synthetics including GTX 5/30, but I've not seen one with HDEO's.

As a gently-driven DD which is using no oil, I don't see a whole lot of reason to change what you're doing. This oil is specially engineered to prevent the harmful build-up of sludge while protecting against new sludge formation better than tough industry standards.

I can show you uoa of rotella in my shared sump bikes but gtx cannot be compared because it can't be used in a shared sump bike because of friction modifiers.
