i just changed to rotella 5/40.. ill see how it goes ... also i put in 1/2 qt of lucas syn oil stabilizer .. about 5 of my buddys have sti's and wrx's and all use that mixture and it seems to work like a charm.. only have about 100 miles on new oil so .. ill be keeping a nice look at at .for miles to come.

po got alot of dealer oil changes but i dont think 05 calls for syn oil . im assuming they just used reg oil
