1980 911 sc oil discrepancy
Hi just joined the forum, will be getting my 1980 911 sc in petrol blue this week, I had one important question, I just want to know what kind and type of oil should go in this car, I read a few posts on here about this but not a definitive answer. If anyone can help me on this subject I would be appreciative. So its what brand of oil and what type and where would you get it. Do I go with reg oil or blend or full synthetic?

Here is the current recommendation from Porsche ... 
http://www.porsche.com/usa/accessori...toroel-10w-60/
The Porsche Classic Motoroil comes in two different versions:
20W-50 for all 356, 914 and 911 models up to the 2.7-litre G-Model and
10W-60 for flat-six engines from a displacement of 3.0 litres up to the 911 type 993.
Starting from the 3.0-litre engine with dry-sump lubrication, the flat-six engines of the 911 are more suited to fully synthetic oils. They allow air-cooled engines to reap all the benefits of technological advances in oils. Porsche Classic's 10W-60 version is an absolute ultra-high-performance oil. Its viscosity guarantees optimum lubrication behaviour, both during cold starts and in a hot engine at full throttle. The fully synthetic PAO-based (polyalphaolefin) oil also has excellent properties in terms of evaporation loss, HTHS and shear stability. Anyone venturing onto a race track in a 911 would also be well advised to use the 10W-60 oil, since it cares for and cleans the engine. For example, the additives ensure that the flow of oil reliably transports particles and contaminants to the oil filter.
The oil change intervals for individual vehicle and engine types can be found in the relevant driver's manuals. Engine oil should be changed once a year regardless of distance travelled, since short trips can have a particularly adverse impact on oil. Frequent cold starts mean that increased quantities of fuel, combustion products and moisture enter the oil. This is compounded by the fact that the engine never heats up properly and hence the by-products cannot evaporate. Your first port of call for an oil change should be a Porsche Centre. This is where customers can purchase the Porsche Classic Motoroil in one or five-litre containers. It's worth mentioning in passing that the container itself is a real eye-catcher, designed by the Porsche designers in the Development Centre in Weissach.
Matching oil filters are of course also available from every Porsche Partner in addition to the Porsche Classic Motoroil. And if you're going to be using original Porsche oil in your original Porsche, you're going to need an oil change label in the engine compartment. Porsche Classic has designed one to match.

As you can tell, there isn't just once answer. Main issue is only a few modern oils have enough zinc and phosphorus (anti-wear additives) to protect our cam lobes. This post kind of sums up the issues:

Common choices are Brad Penn 20W-50, Valvoline VR-1 20W-50, and Mobil 1 15W-50. The first two can be hard to track down, you may have to order the Brad Penn and have it shipped.
I don't think you want to mess with an oil filter from Autozone or anyplace like that. You want to get a Mahle, probably need to order a few online. Pelican Parts is a good source of parts, but there are certainly others out there.

What oil has the car been using??? How many miles on the engine??? If you can find that information, it will be very useful in order to offer a recommendation.
Sometimes switching from dino oils to synthetics can cause significant issues so this is a consideration.
