2002 Subaru Outback L.L. Bean H6 3.0
Installed Mobil 1 M1-104 oil filter and used 1 quart of Mobil 1 10W-30 Extended Performance, 1 quart Mobil 1 10W-30, 1 quart Quaker State Torque Power 5W-30, 1 quart Super Tech 5W-30 synthetic, 1 quart Valvoline Synpower 5W-30 synthetic, and 1 quart Motorcraft 5W-20 synthetic blend.
I had leftovers to get rid of. I just added the 4oz Auto RX maintenance dose a couple days ago (1100ish miles on oil) because I didn't have any Auto RX on hand at the time of the change.
