Just got back from the dealership. They charged me $22 for the filter + oil change with tax. I ended up getting another quart of oil from walmart before I went there just in case. They used a tiny bit of that last quart and I have it back for future oil changes. So my total was $37 (oil) + $22 (filter+change) = $59. Not bad and I have that oil for future use so it should cost only $52 next time!
Also I talked to one of the service advisers and he said they were cool with mods.
