Nicely,
It is great to know that you stand firm by your believe.
As for me, I've seen too much of uncertainty in the engineering field in my career, especially regarding premature failures that cannot be explained.
I have a W124 in my family for 19 years, it has been feed on mobil 1 syn lub (changed every 10000km) and mercedes coolant since day1. 270000km later no. 1 cylinder lost compression. The engine was striped for a rebuilt. The internals of the head and chambers were in perfect condition but the culprit that caused cylinder 1 to loose compression was a bend valve. How and why beats me?
For my 4 months old Murano, I service it the same way as above.
It is temperature and pressure that kills a combustion engine. We all know that it just takes a few seconds of detonation to bust a motor, so there is no certainty that the oil will not break down prematurely under higher temperature environment of a boosted engine. I guess that race teams strip and rebuilt engines after every race for the same reason of not taking any risk, right?
It just does not make sense for many of us to fit oversize radiators and oil coolers as insurance to manage the engine temperature, yet take the risk over saving a few dollars on oil usage.
As for a 1.2bar boosted turbocharged SR20DET in my s15 that has a full aluminium head + block w/o steel sleve, I don't take my chances like the above.
