There's a lot to digest in this presentation but my initial reaction is as follows...
Anything that gets engine oil up to normal operating temperature as soon as possible and importantly, keeps it there, is IMO a very good thing. And yes, I agree that such a measure would result in better fuel economy and lower emissions (although the degree of savings would rather depend on whether you lived in Finland or Singapore with the colder countries having most to gain).
Having said that, I would not rate the chances of this technology ever being widely adopted. My reasons for saying this have nothing to do with the technology itself and everything to do with the attitudes and collective psychology of the OEMs.
IMO, the OEMs have evolved into being 'problem shifters' rather than being the 'problem solvers' they should be. The truth is that the OEMs could have developed appropriate engine tech to control and maintain oil temperature decades ago. I'm a chemical engineer so I know this kind of thing isn't rocket science! However what we saw was the OEMs off-load the problem of improving fuel economy, more or less wholesale, onto the oil companies. The result was the trend to ever thinner oils. This way the OEMs minimise the manufacturing cost of their vehicles but shift the cost on to the customer by way of ever more expensive oils. They have also off-loaded the problems which can be caused by ever thinner oils onto customers in the sure and certain knowledge that these will occur out of the warranty period.
You could argue that they did similar things when it came to exhaust after-treatment. With gasoline three-way catalysts, rather than put a few more pennies worth of platinum on the substrate, they chose to (a) restrict the level of ZDDP (or Phosphorus to be more exact) in oil and then (b) impose a Phosphorus Volatility restriction on the Sequence IIIG which pushes oils to use a higher percentage of heavier ZDDP, adding cost to the oil at nil cost to the OEM. Likewise, when it came to reducing diesel emissions, rather than introduce tech that actually worked (like the stuff they're now being forced to introduce) and not third-rate DPF's which coke-up at 60,000 miles, they send the oil companies off to develop low SAPs oils in the vain hope that this will get them through.
Maybe I'm wrong. After Dieselgate, maybe the OEMs will start getting their own house in order and start figuring out 'proper' fundamental fixes to some of these issues. Maybe the tectonic plates are shifting...but I'm not holding my breath...
