In Europe there are 2 oil regimes. 1 - Longlife 504.00 which is 5W-30 and is variable service intervals based on oil condition & distance *. 2 - Fixed 10K intervals, 502.00, which is 5W-40.
* - that's what the sensor in the sump is for. It's not just a level sensor, its also reads the opacity of the oil.
The Longlife stuff when it used to be Castrol was horrible. It varnished the internals that familiar goldish dark brown colour, and if not changed regularly, the excessive carbon and acidity wears the chain out and stiffens the valve guide seals into a plastic state.
Yeah that's the thing with oils like NanoDrive and other 'race' spec oils. They rarely, if ever, come with manufacturer approval because it doesn't meet particular standards which race engines don't need to be concerned with.
If Ester oil is your thing, then I would be using Fuchs Titan Pro-S (formerly known as Silkolene) or Motul Sport 5W-40, or 300V if you're really posh.
Quantum Platinum is plenty good enough these engines though. The frequency of change is more important than the quality of oil, especially on an engine that only has 1 very small chain and 1 tiny flat tappet, so cheap stuff is fine. There's hardly any friction and its operating temp range does not stress the oil at all. A twin turbo V8 revving to 8500rpm, then yep, I'd be using Motul 300V!
