I have 3L of Catrol Edge 10W60 from my old E92 M3 and I was going to stick with this but then started reading about engine oil... obviously I am now rather confused about the subject.
I am tempted to try Millers Nanodrive CFS N+ 10W60 based on what I have read so far. Any thoughts on this oil and the weight? Opie Oils in the UK seem to recommend 5W40 for these cars but many seem to be using at least 10W50. I am located in Prague, Czech Republic and the car is mostly going to be used in better weather.
You need an oil with sufficient amounts of ZDDP to prevent premature wear on cam lobes and rockers.
I have no idea what the ZDDP level is in the Millers oil I am considering. I did read something somewhere that seemed to indicate that it can be too high as well and that it's not necessarily the case that a higher ZDDP level equals less wear. Certainly higher than the Porsche classic oil would be a good idea though based on what I have read thus far!
I've been recommend by my engine builder and I'm sure others will chime in on this contentious subject. Penngrade (formerly known as Brad Penn) 20W-50 is what I use.

Interesting - a 20W50. I should have put a poll on here...
That brand seems to be quite popular but I'm not seeing it in Europe.

Likely not needed. This has been such a hot topic over the years with numerous threads. I'm going to hide now before I get stoned
Not having looked into this in the past I am interested in what people are choosing and why they might go for a 20W50 instead of a 10W60, for example. I guess 20W instead of 10W would be better for the engine on cold starts in colder climates? I've next to no idea other than what I have read in the last day or so.
I won't take the bait and start arguing about brands of oil. But as far as oil weight goes, I would suggest a good read of your owner's manual as an excellent starting point.

Well, I do not have an owner's manual and it was written over 30 years ago, so I thought asking the fine people of this forum would be a good idea. Things change over time - collective knowledge and oil technology, etc.
My question wasn't bait either - it was just a question, with no reason for any arguments and none in evidence thus far. Just people sharing their opinions and advice in a friendly and helpful manner. Mostly.
Well, I can see my attempt at humour has been an abysmal failure.
But asking about oil, is kind of like asking who has the best hockey or baseball team. It invokes strong feelings and often results in heated debates. This is why others in this thread have referred to it as a "hot" or "contentious" topic.
Anyway I had no idea you did not have an owner's manual. Here is an excerpt from the 964 manual that may be useful. Cheers!

Indeed it did, but a failed attempt at humour is better than what I thought you were doing (the old 'read the manual' comment).
I appreciate you taking the time to post that excerpt - I wonder if the recommendation has, or would have, changed over time as oil technology has (presumably) changed. Maybe it hasn't really changed as much as marketing would make us think? I've no idea. The recommendations in the manual are interesting. Based on my location I think 10W50 should be fine.
I guess also oil technology has come a long way since the handbook was written - not from a view of not relevant, but more the types/grades of oil that are now able to be 'modified' for types of use and engine mileage/hours (e.g. track vs road vs classic etc).

Agreed. The API designations evolve over time. I would also expect the owner's manual does not take into consideration a racing application.
Here is a brief history of API oil categories and classifications.
