Every time you post things like this, you torpedo your own position.
To wit: While sludge often results
from poor upkeep, notably not changing the oil at prescribed intervals, some engines appear
more prone to sludge buildup than others *If it was the oil as you like to claim, all of them would be, despite TLC.*
Engine failure due to sludge is a major problem for car owners, and automakers appear to have been slow to address it, generally linking it to poor maintenance rather than to
a problem with the engine *no mention of inferior oil here.*
Toyota staunchly maintained that any such "oil-gel" problems are attributable to
owners' abuse or poor maintenance habits *Note that Toyota doesn't blame the oil*.
I've already covered the class action suits...
And from one of your other links:
Industry experts say modern engines are even more prone to sludge build up than older ones. So what’s the cause, and why is it making a comeback?
There are several key reasons.
Crankcase Ventilation.
Oil vapour and combustion gasses must be removed, usually by being channelled through the combustion process.
If these gasses are not disposed of efficiently, sludge will form. Some modern breather systems are more successful than others.
Temperature.
Changes to the positioning of the Catalytic Converter have led to changes in temperature, hot and cold spots, in and around the engine. Hot spots bake oil, cold spots cause acid and sludge.
Crankcase Acidity.
Modern fuels produce much more acid when burnt. A proportion of this acidity enters the crankcase. Experts say that long term engine wear is now as likely to be down to acidity as friction.
Tighter Tolerances.
Engines are no longer manufactured down to Thousandths but Microns. Tighter tolerances mean engines are
using less oil, and as a result customers fail to check levels and miss oil changes
Poor Maintenance.
Drivers who miss recommended oil changes are without doubt contributing to the problem. Lease vehicle drivers especially are quoted as being among the worst for neglecting DIY level checks.
City Driving.
Constant stop/start city driving accelerates sludge formation. Drivers who spend most of their time in urban traffi c should be advised to book oil change services more regularly.
Don't see any blame on oil there either.
