My wife caved and said I could change her Subarus oil! She wanted dealer while under warranty. The first 3 were dealer changed. I am using a Subaru filter ($5.50 each if I bought 3) and M1 0w20 as it requires syn and it is still under warranty. I'm excited to change oil on a car with an oil filter I don't have to burn my arm on hot exhaust to get off. M1 on sale at WalMart if you're interested.
