I know these euro 40's are borderline 30, but this crossed the border.
No in -situ problems if the HTHS is stout.
IN fact, its better.
but still a surprising failure.
Yeah it's definitely a thinner 5w40. Even the non SN Plus formulation was right there on the edge between 30 and 40. I like my oils thick since I live in a hot climate.
It's your vehicle oil temp reading in operation that matters, not the Climate.
Granted most will rise with higher ambients. But are you even pushing 205degF?
Also HTHS ( not tested or reported) is the "protection" not the KV100.
I would hazard a guess the Viscosity ERROR was on blackstone.
But it would be interesting to retest - or test somewhere else.
If it's out of spec range, its a FAIL; Personal feelings don't come in to that asssessment
If PQIA tested it out of range, it would get a red - or at least yellow flag.
