Working on these cars for 13 years we never had an engine failure due to oil ... or low oil and the engine blew.
Interesting take on things, I wonder where the oil went and why. Low oil caused engine failure within 5000 miles of an oil change, that's either a pretty big leak that should've been caught or the engine was burning it due to rings or valve guides. Not sure how you can conclusively say oil wasn't a factor.
Today's oil no matter synth or not blows away the oils of yesteryear and if those oils could stand the punishment troopers give those engines, you will never see (ever) an engine related problem caused by todays oil. Use what you want as long as it meets the specs and be happy.
FWIW, I only use Mobil 1 in the SRT8 because 0w40 does not exist other than Mobil 1 and Pennzoil and Pennzoil 0w40 can only be purchased from dealers (in my area) so Mobil 1 wins.
I agree, proper maintenance with proper fluids and parts is the most important thing you can do for your car, but that doesn't mean there are no advantages to better lubes. There's a reason synthetic oils are called for by the manufacturer, be it for the engine, transmission, or diffs.
ATF+4 is synthetic
Our rear diffs call for synthetic gear oil
SRT vehicles come with synthetic engine oil from the factory
If conventional lubes worked just as well then they wouldn't be specifying synthetics. Fact is, our vehicles see higher internal operating temperatures and in many cases conventional oil would break down and not be able to protect at those temps.
My car gets Mobil 1 in the engine and diff, trans gets whatever ATF+4 is the cheapest since they're all the same.
