Works great on my 06 Subaru WRX STI

Started using this Shell Rotella T6 oil instead of Mobil1 when I noticed that I was losing more oil between oil changes. From the few popular Subaru forums, they seem to have a consensus that the Mobil1 is too thin and gets past the turbo seals and gets burned off as a result. Started using this and definitely have noticed less oil consumption.
