Of course a couple of months doesn't matter. I would never use a boutique brand oil in an expensive car engine, because they won't pay on an oil claim. That means redline, amsoile, hpl are out. If your car qualifies on a major US oil co. warranty, I'd use their oil. The main thing is: don't short trip the car, don't keep moving it from one side of the garage to the other. The 4.9 l tipo f-113 12 cylinder engine is not durable, by it's very nature as a ferrari. It must be babied with bulletproof maintenance.
