Question about 1985 Porsche 911
Well this is always a hot topic and I'm sure you could get at least ten people that would be willing to kill each other over their particular rationalization, but for me, the choice is simple. It has to be a synthetic just because it flows more easily when cold and it has a higher oxidation temperature so the ring lands are less likely to get carboned up and cause oil burning. The brand is not that important to me as long as it is well known. The weight should be something near 10-30w. I personally don't think a few points away from this is going to matter. You will have people tell you that you must follow the manufacturers recommendation to the letter. Well, we're 25 years beyond 1985 and modern oil in this engine is more than adequate in a variety of flavors.
