Hello question… i have a 97 BMW 740il 162,359 miles.today my dad told me that when he was.moving the car that it had an oil leak. My car isn’t the only one in his driveway as we do share but he said there was a spot under it when he moved it. The car has been there for 2 weeks. When i drove it, it drove perfect. Is it possible i might Still have a leak or???
