There is a point i forgott:
Today, you can do one thing wrong: Use a modern Diesel or energy saving, low HTHS, low viscositiy oil in a classic highly tuned gasoline engine, like our S2000. Stay away from theses oils and read the label carefull.

Blackstone labs is right, most oils do a very good job. But, one point is missing: The Oil change intervall.
There is a dedicated oil forum in germany, too. In the used oil analysis posted there you see the trend that even the best full syn oil can just manage to go about 15.000 Km / 9000 Miles, then it´s sheared down, thin, just wasted and used. Otherwise, most oils do a very fine job.

Used Oil: https://oil-club.de/index.php?board/...raucht%C3%B6l/
Fresh Oil: https://oil-club.de/index.php?board/2-frisch%C3%B6l/

So: Use the weight according to the handbook, use you prefered brand, use a Group III / IV Oil, use a oil that carrys demanding OEM approvals and change it often. Done.

For everybody interested, there is a dedicated wonderfull Book:

"Which Oil? - Choosing the right oils & greases for your veteran, brass era, vintage, antique, classic or collector car
by Richard Michell"

This book explains everything. You will find it online. The book title is a little bit missleading, the book covers also the modern era up to the end of the 90s.

 

Thanks for the clarification man. I went and looked up Motul 8100 Xcess and found some conflicting arguments but for the most part it seems that it isn't purely group IV full syn. That being said it is proven to be a very good oil. I have no problem staying with it in my S2000 and Corolla. On the other hand I may even give Liqui Moly high tech 5W40 a go as it is available here in South Africa. Then again I want to upgrade to Motul 300V which is undoubtedly a group IV/V full synthetic ester core oil That price though... haha. Still I really don't mind and the placebo effect alone may be well worth it.
I read that Motul 8100 Xmax 0W40 is apparently a group IV oil... that is available here as well. Still researching Xclean 5W40...

At the end of the day I want an extreme oil for an extreme car

 

I hate it to say, but the X-cess 0w-40 also is Group III. Here are the screenshots from the german Motul Homepage.

 

And here are the Screenshots from the LM Hompegae, note the word "Vollsynthetisch", that means full syn= group IV. Only 5 from 43 different oils for cars in the LM product range are full syn.

 

@ Rolan THUNDER: What about the australian made Penrite Oils? They are clealry labeling their oils in terms of PAO / Group IV and they have some fine oils with genuine approvals.

 

Honda doesn't make motor oil. It's fine to use, but I personally prefer full synthetic and just use Mobil-1. But based on how often the oil is changed in these engines (my AP2 2006 calculates maintenance minder about ever 6K) it doesn't matter too much whether it's a synthetic blend or full synthetic. Yes, there are differences, but in the grand scheme of things, even regular dyno is fine. Keep it topped off, change it often and any mainstream brand works.

 

Never even heard of it until now. I was in Australia a few years ago but I didn't go looking for oil there to be honest.
Can we really trust LM when they say "Vollesynthetische"? What if they're also lying about it or its not 100%? I would imagine that German law is quite strict on the matter but still...

 

Things are getting heated in the oil fandom.

 

define good.

 

@ RolanTHUNDER: i just have looked at the Liqui Moly South Afrika HP, they have the same descriptioin as in germany. If they tell its "FullSynthetic", you could trust them. It´s Germanys Nr. 1 Oil brand, best selling, widely used. If you like it, go for it.

@ datadr: Mobil 1 + Fully Synthetic.. err..... not in Germany. But Mobil 1 0w-40 is a incredible good oil.


Real full synthetic PAO / Group IV oil is start to becoming a thing of the past, it seems. Group III oil today is almost as good, cheaper and easier available for the manufacturers, i think.
