I just bought a 2012 outback 2.5i with really good deal (16000 miles at $22k out of door, limited version, with backup camera). But my wife and I ignored the previous service record. It turns out the engine oil was only changed once at 5000 miles according to the dealer service record. There is no lack of oil when I do the oil change myself, just a little dark color. I used mobil 1 oil and filter. It drives no difference. But I am very concerned about this long term no oil change for one year. Will it hurt the engine? I also talked with the service dept at the dealer specifically about the warranty. He said as long as I change oil from now on at 3000 miles interval, they wont deny warranty repair. We plan to purchase gold plus 7 yrs/100k also. I don't know if I should keep this car for long time now. In serious dilemma now.
