With the current price of regular old 5W30 conventional running around $4/qt and the OE oil filter around $8 I'm probably going to take advantage of the local Subaru dealership's oil change special for $29.95. They probably use bulk XOM or SOPUS oil anyhow, and I would be using either Mobil Super 5000 or Havoline so... Might as well drink some coffee and let them get dirty instead. P.S. I probably won't. I'll probably DIY it due to my obsession with perfection and all, but it IS food for thought.
