More Challenges Loom For Engine Oil

Looks like Europe will be following North America rolling out 0W20/5W20 oils.. LOL so much for the needs of the Autobahn...
 
Challenges loom for engine oil or changes in oil choices in Europe (i.e. lower viscosity availability)?

CAFE = fuel consumed per mile traveled
Carbon Emissions = fuel burned per mile traveled

pressures are pressures, political, otherwise, or paid for

In face of the above, "needs of the Autobahn" entail sacrificing consumer costs (longevity of their purchase) for the greater good of pressures, political pressures, or paid for pressures.
 
Downsized turbocharged engines in 2-ton cars running 20 or 16-weight oils sounds like a recipe for disaster to me. The higher-stressed engines will need to be built to tighter tolerances on bearing clearances to maintain oil films at the high side of the tolerance range. Bearings will need to be made from higher-strength materials to withstand higher unit loading. Exhaust valves will need to be made from Inconel or better grades of material or be sodium-cooled to withstand higher combustion chamber heat and pressure.

So the downsized turbocharged engine will end up being more expensive, completely offsetting the 1% fuel economy gain that necessitated redesiging them to run the thinner oil in the first place. Doesn't sound like progress to me. Technically, it's all interesting. But it's not cost-effective for the end user.
 
A good quote from the article:

Quote:
Another area to consider is wear. Calder noted that "as we use thinner oils, we're going to get into lubrication regimes where wear will become more of a concern." More boundary lubrication occurs with lower viscosity oil, increasing the potential for higher levels of wear. "There are things we can do to change that," Calder said. "For instance, advanced detergents, dispersants and inhibitor packages are being investigated that can move the lubrication regime back into the hydrodynamic region, improving wear performance."
 
^ I noticed that too.

I didn't necessarily buy into that last sentence. How can a DI package move the lubrication regime from mixed back into hydrodynamic?
 
Lubrizol is just preparing for the challenge. There is nothing official yet, but the move makes sense considering the influences on the industry. If current tech could provide the benefits of our current North American low-HTHS oils and withstand the demands of European driving and drains in any sort of economical capacity, then it wouldn't be an impending challenge!

Whatever the reasons for all of these moves, this will spur the industry- yet again- to rapidly advance oil technology. Or at least get creative in making it economically viable. Can't complain about that

+1 also curious about this

+2

I think a more accurate statement would have been something along the lines of: advanced anti-friction/anti-wear packages can greatly limit the amount of wear in the event of boundary layer lubrication occurring. Something like that would make a lot more sense to me.
 
Okay, what will happen to prices when they introduce PAO in larger quantities. Was it 3 or 4 times the cost of Grp III. Especially in Europe where we already have to pay 50-80€ / 4L for these GrpIII, IV, V blends. Then they put some hyper uber new additive packages, ouh voila we pay like 30€/l.
