I noticed a bad oil burning smell in my Company car (2012 Subaru Legacy) and oil in my driveway. I went to a Merchants tire shop because it needed new tires so they investigated the oil leak. Turns out those idiots at the Quick lube havoline shop, didn't even tighten the oil filter all the way. The guy said that he was surprised that it didn't back itself off all the way it was so loose. I can't believe I didn't lose oil pressure. Moral of the story. Change your own oil. I would have but it's my company car and goes through the fleet service.
