Talking about oil, back, a long time ago when I had a good paying job, I had an old Porsche 911. The mechanics had me use oil made by a company called Swepco. This is the oil of choice for Porsche mechanics, and I must say its very expensive, but it's the best oil I've ever bought. It's not synthetic. Porsches of that era were totally oil cooled, in other words, Porsche mechanics really know their oil products. You can't buy it at K-Mart, you'll have to go through a vendor, but if you're really picky about oil you should check it out.
