imploding...is that a new SAE standard or burden of proof ?
See the hyperbole that you people bring to any discussion is the childish part...
Find a single post where I have once suggested the
* pile of failed engines
* engines imploding left right and centre
* engines failing just outside of warranty...
All of which your team has placed in my mouth.
I am offering what the OEMS and legislator are saying.
They are trading off economy (or CO2, pick your market), while trying to make "acceptable" compromises in longevity (that's Honda)
That they put in performance management systems to neuter the engines when it's performance envelope outstretches the lube they put in (That's Subaru/Toyota in the BRZ/86 "sports car")
When they do so, they MUST make every reasonable effort to ensure that owners use those lubes (that's the EPA to Honda and Ford).
And if the car makes it to the junkyard with 100,000 miles left on the engine rather than 150,000 miles, it's a perfectly valid tradeoff.
